PE Threaded Fittings for HDPE Pipe Connections
Our PE threaded fittings are precision-molded from high-quality polyethylene material, designed to meet international standards for HDPE pipe systems. These fittings offer excellent sealing performance, dimensional accuracy, and long-term aging resistance, making them ideal for water supply, gas distribution, irrigation, and industrial pipeline transitions.
Unlike fusion fittings, PE threaded fittings provide a quick and convenient mechanical connection solution, suitable for both new installations and repair works without the need for heating or fusion equipment.

How They Work?
PE threaded fittings use precision-cut threads to connect with pipes, adaptors, or other threaded components. When properly tightened, the threads compress and lock with the HDPE pipe interface, creating a secure, leak-resistant mechanical seal. This design eliminates the need for welding or fusion equipment, making installation fast, convenient, and suitable for confined spaces or field repairs.

FAQ
Q1: What is a PE threaded fitting?
A: A PE threaded fitting is a polyethylene connector with molded threads designed for HDPE pipe systems, providing leak-free connections without welding.
Q2: What pressure rating do PE threaded fittings support?
A: Depending on size and design, most fittings are rated up to PN16 or PN20 for water and gas applications.
Q3: Can PE threaded fittings be used for gas lines?
A: Yes. They are widely used in low- and medium-pressure gas distribution systems, provided they meet relevant local standards.
Q4: How do I install PE threaded fittings?
A: Ensure the pipe is clean and aligned, then screw the fitting into place using the correct torque. No fusion machine is required.
Q5: Are PE threaded fittings resistant to aging and UV?
A: Yes. They are designed to withstand outdoor conditions with strong resistance to UV radiation and material aging.
Q6: Can these fittings be used underground?
A: Yes. With proper installation and protection, PE threaded fittings can be safely used in buried pipelines.
Q7: What are the main applications of PE threaded fittings?
A: They are widely applied in water supply, gas distribution, irrigation, municipal, and industrial pipelines.
