Polyethylene threaded fittings are divided into three types: threaded, welded, and compression. Threaded fittings connect to the female ends of pipes using threads inside or on the fittings and are used for small projects and small pipes. These polyethylene threaded fittings come in various types, which we will discuss below. Threaded fittings (threaded connections) are used to connect two polyethylene pipes without the need for welding. These fittings consist of different parts and are mainly used in water supply systems and irrigation of agricultural and farmland. Threaded fittings are made of polyethylene and produced by injection molding. Polyethylene Threaded Fittings Types of Polyethylene Threaded Fittings Polyethylene fittings include female fittings, male fittings, flanged fittings, polyethylene couplings, equal tees, equal elbows, female elbows, male elbows, female tees, male tees, end caps, and reducing tees. Female Fitting This type of fitting is used to connect to valves and male threaded polyethylene fittings. For a more secure and reliable connection, it is better if both fittings are of the same material and family. Male Fitting This fitting has one end as a coupling and the other end threaded. This type of polyethylene threaded fitting is used to connect polyethylene pipes to threaded valve fittings. Flanged Fitting This type is also threaded and is used to connect polyethylene pipes to cast iron valves or any flanged connection. The flange is made of steel and can be easily opened and closed using bolts and nuts. It is used in pressure vessels, compressors, pumps, and more. Polyethylene Coupling This complex fitting is used to connect two ends of polyethylene pipes and can increase the pipes' resistance to stretching, expansion, and contraction. Equal Tee This fitting is used to take a branch and comes in various sizes. It is used in water supply, irrigation, and gas distribution industries. Since all three connections are equal and identical, it is called an equal tee and is used as a divider, connector, changer, and joiner. Applications of Polyethylene Threaded Fittings Fittings are available in various sizes and qualities for fields such as agriculture, household and construction uses, urban and industrial sewage, fisheries, and more. They are also widely used in the transmission of gas and chemicals. Polyethylene threaded fittings have high resistance to weather changes, corrosion and abrasion, pressure, and impact. Additionally, their non-scaling, ease of installation, long lifespan, reasonable price, and flexibility make them among the most commonly used fittings. Urban and rural water supply systems Non-potable water networks (such as green spaces and parks) Industrial installations for transferring acidic and alkaline chemicals Drip and sprinkler irrigation networks in agriculture (under pressure) Use in transporting wastewater and industrial sewage Advantages of Using Polyethylene Threaded Fittings Durability and Longer Lifespan These fittings have a longer lifespan and durability compared to similar metal, steel, and cast iron fittings. Depending on the application, design model, and installation location, their average lifespan is estimated between 50 to 100 years. High Corrosion Resistance A common problem in metal piping is corrosion (both internal and external), which affects hydraulic efficiency and incurs high costs for consumers. Using polyethylene threaded fittings ensures very high resistance to corrosion. No Need for Specialized and Heavy Tools To create connections with polyethylene threaded fittings, you do not need specialized or heavy tools and can install fittings using basic tools. No Need for Protective Coatings Many fittings require protective coatings to resist rust and other issues, but threaded fittings do not need special protection. Low Cost These fittings are much more cost-effective compared to others. The impact and pressure resistance and flexibility of polyethylene pipes and fittings are sufficiently high, eliminating the need for anti-impact equipment. Minimal Space Required for Installation Threaded fittings can be installed in very limited spaces without needing large areas. No Expertise Required Unlike welded fittings that require skilled specialists, threaded fittings can be installed without any special expertise. Speed of Work Installation of threaded fittings is much faster compared to other types, allowing completion in minimal time. Advantages of Threaded Fittings Long Lifespan: Since threaded fittings are made of polyethylene, they can be used with confidence due to their long lifespan. Easy Installation: Due to their threaded nature, they do not require high technical knowledge, additional equipment, or skilled labor for installation. Easy Repairs: As installation is easy, replacement and repairs are also simpler compared to other models. High Temperature Resistance: These fittings can withstand temperatures even above 80°C. High Pressure Resistance: Threaded fittings can tolerate pressures up to 10 bar, making them popular in industries. Minimal Leakage: Due to their structure, threaded fittings have the lowest leakage rates. Components of Polyethylene Threaded Fittings 1- Split Ring The split ring prevents the pipe from coming out of the fitting under pressure. It is made of polyacetal, which can withstand high pressure. 2- Bushing The bushing is placed between the O-ring and the split ring and presses the O-ring during connection to enhance sealing. 3- O-ring Made of rubber, the O-ring must be highly flexible and pressure-resistant. Its function is to seal the connection. 4- Body and Nut The body and nut of threaded fittings are made of polypropylene, which has higher resistance to pressure, temperature, and UV rays compared to polyethylene. The ends of the pipes to be connected must be clean in all respects, and the fitting parts are installed on the pipe. The handle length for these fittings is no more than 46 cm; otherwise, Teflon tape is required. The list below includes types of polyethylene threaded fittings: Equal Elbow Male Elbow Reducer Tee Female Tee Male Tee Tee (Equal Tee) Saddle Reducer Nipple Polyethylene Flange Adaptor Female Polyethylene Threaded Adaptor Male Adaptor Threaded End Cap Reducing Coupling Coupling Female Elbow Due to their unique features, polyethylene pipes and fittings are used in very large industrial projects.

. Introduction The monopump stator is the fixed rubber part of progressive cavity pumps that, alongside the metal rotor, enables continuous transfer of thick, viscous fluids or those containing solid particles. Choosing the appropriate elastomer and stator structure type (with or without cover) plays a decisive role in service life, efficiency, and maintenance costs in industries such as foam concrete, olive oil extraction, food, and steelmaking. 2. Technical Definition of Monopump Stator The stator is a rubber liner with a double helical internal cavity, usually molded and cured inside an outer metal tube (cover). The metal rotor with a simple helical geometry rotates inside this cavity, and the moving cavities transfer fluid without noticeable pulsation. The quality of rubber adhesion to the cover (in covered types), dimensional accuracy of the cavity, and uniform rubber thickness are key performance factors. 3. Technical and Engineering Review Stator performance depends on several parameters: Dimensional fit with the rotor: improper interference fit causes pressure drop or premature rubber wear. Chemical resistance of the elastomer against the process fluid (oil, water, alkaline substances, grease). Thermal resistance and compression set: loss of rubber elasticity at continuous operating temperatures. Abrasion resistance against solid particles suspended in the fluid. Quality of rubber adhesion to the metal cover (in covered design) to prevent rubber delamination during operation. Materials and Raw Materials Review Elastomer Oil Resistance Water/Alkali Resistance Operating Temperature Suitable For NBR High Medium Medium (grade dependent) Steelmaking, Oil EPDM Low High Medium to High Foam Concrete Food Grade Rubber Depends on base (NR/EPDM/Silicone) High Medium Food, Olive Oil Extraction HNBR High Medium Higher than NBR Steelmaking, Heavy Abrasive Environments Exact temperature values, hardness (Shore A), and chemical resistance must be confirmed from the datasheet of the used formulation or reference standards (like ASTM D2000); no elastomer is absolutely superior for all fluids. Types and Classification of Stators Standard Stator (with metal cover): rubber is cured inside a steel tube; offers higher structural strength and resistance to internal pressure. Coverless Stator: rubber is formed without an outer metal tube; lighter weight and lower material cost, suitable for specific designs and connection types. Stator with NBR Elastomer: for oily fluids and petroleum/steel processes. Stator with EPDM Elastomer: for water-based slurries like foam concrete. Stator with Food Grade Elastomer: for direct or indirect contact with food and olive oil. Industrial Applications Foam Concrete: pumping air-entrained cement slurry with fine particles; EPDM is commonly chosen due to water and alkali resistance. Olive Oil Extraction: requires hygienic compatibility and no odor/taste transfer; food grade rubber is preferred. Food Industry: strict hygiene requirements and frequent washing; selection of grades with food contact approval is essential. Steelmaking: abrasive and sometimes oily slurries at higher temperatures; NBR or HNBR are generally more suitable. Stator Selection Criteria Fluid type and chemical compatibility with elastomer (oily, water-based, food) Continuous operating temperature and pressure Solid particle content and fluid abrasiveness Hygiene requirements or food contact approvals (if needed) Pump installation and connection type, to decide between covered or coverless stator Production and Custom Manufacturing Process Jam Rubber Manufacturing produces monopump stators for foam concrete, food, olive oil extraction, oil, and steelmaking industries, both standard with metal cover and coverless. Elastomer type, precise helical cavity dimensions, and structure type (with/without cover) are finalized based on customer fluid specifications or technical drawings. Technical Comparison: Covered vs. Coverless Feature Covered Stator Coverless Stator Structural strength against internal pressure Higher Medium (design dependent) Weight and material cost Higher Lower Ease of installation in some designs Common standard May be simpler Selection between the two types should be based on actual system working pressure and pump connection type in consultation with technical teams. Common Errors in Selection or Use Using EPDM in oily fluids, causing swelling and rapid rubber degradation. Ignoring proper interference fit between rotor and stator, leading to pressure drop or premature wear. Choosing coverless stator for operating pressures exceeding its design capacity. Frequently Asked Questions Is one elastomer type suitable for all industries? No; elastomer selection must match fluid type (oily, water-based, food) and each industry's operating conditions. When is a coverless stator recommended? Usually for specific designs and operating pressures where lower weight and cost are important; suitability should be reviewed with technical teams. What is the main difference between NBR and EPDM in stators? NBR has higher oil resistance, EPDM has higher water and alkali resistance; selection depends on the dominant fluid type in the process. Summary and Conclusion Choosing monopump stator material — NBR, EPDM, food grade rubber, or HNBR — and its structure type (with or without cover) must be based on fluid type, temperature, pressure, and industry hygiene requirements (foam concrete, olive, food, steel). Jam Rubber Manufacturing has experience producing both stator types for these industries; sending fluid and system technical specifications to the technical team is the most accurate way to select appropriately. Sources and References ASTM D2000 (classification of industrial elastomers), general food contact standards for elastomers, and technical datasheets from rubber compound manufacturers; exact temperature, hardness, and chemical resistance values must be verified from the formulation technical documents.
