HDPE Pipe Coupler

The HDPE pipe coupler boast outstanding material performance features: they operate stably within a temperature range of -20℃ to 60℃ without cracking under frigid conditions, are non-toxic and safe for direct contact with drinking water, making them suitable for potable water supply systems.The following four common types.

Electrofusion Coupler

Built-in heating wire creates fully leak-proof molecular fusion. Straight, reducing and slip repair types available, OD20–OD630, PN10/PN16.

Butt Fusion Coupler

Suitable for large-diameter solid HDPE pipes OD75–OD1000. Joined via butt welding machines, they feature outstanding pressure resistance for municipal main pipelines, landfill leachate pipes and industrial recycled water systems.

Compression Coupler

Fits OD20–OD63 small HDPE pipes. Push-fit with rubber seals, weld-free, reusable. Ideal for domestic water and small greenhouse irrigation.

Layflat Hose Straight Coupler

Special for flexible flat irrigation layflat hose and PVC coated water belt. 3 anti-slip outer ribs, hose wraps outside the fitting and fixed by hose clamps. Working pressure 0.4-0.6MPa.

Product Advantages

the fittings deliver powerful resistance against corrosion caused by fertilizers, sewage, weak acids and alkalis. They also offer an impressively long service lifespan, lasting 5 to 8 years for outdoor farm irrigation projects and up to 50 years when buried underground

Leak-Free Reliability This HDPE pipe coupler locks pipes together into one solid piece. No weak spots at all, so you’ll never have leakage issues.

Corrosion & Chemical Resistance These couplers never rust like metal ones. They work perfectly in acidic soil, chemical factories and salty coastal areas.

Flexibility These couplers combine outstanding flexibility with robust toughness. They withstand ground subsidence and sustained vibrations without cracking, maintaining the full integrity of your pipeline.

Quick & Easy Installation Lightweight for easy transport and quick assembly.Only one worker is needed without professional tools; each pipe connection can be finished within 60 seconds.

Shuoxin® HDPE pipe coupler is core fittings for joining HDPE solid-wall pipes. They see extensive use in municipal water supply, gas delivery, sewage discharge, agricultural irrigation and industrial fluid conveyance.

It is crafted from virgin HDPE, our couplers deliver superior corrosion resistance and cold resistance.
