Heat Shrink Coupler for HDPE Pipe Jointing
Heat Shrink Coupler joints sections of corrugated HDPE pipe with a hot-melt adhesive lining sealed to IP68, replacing butt welding, snap-fit or split couplers on water, sewer, drainage and underground cable-duct lines.
- Hot-melt adhesive lining seals to IP68
- ASTM D638
- ASTM D2671
- ASTM D2240
Dimensions & Drawings
Heat Shrink Coupler is a Tubing suitable to joint Corrugated HDPE pipes, used in Water management, Irrigation, Sanitary, Sewer and Drainage, Construction, Mining industries, Ducting and for underground Cable protection.
These tubes are manufactured from cross-linked polyolefin. Hot melt adhesive lining provides 100% sealing according to IP 68 (Ingress Protection).
It is feasible and the most economic jointing solution compared to Conventional Butt welding or using Snap Fit Coupler or Split coupler.

FAQs
Frequently Asked Questions
What is the Heat Shrink Coupler for HDPE Pipe Jointing used for?
It is used for:
- Water management and irrigation piping
- Sanitary, sewer and drainage lines
- Construction and mining industries

How is it installed?
Clean and degrease the surface, position the part, then shrink it with a gas torch or a hot-air gun: keep the heat moving round it with a smooth, brushing motion so it recovers evenly without scorching. Start at one end and work steadily along to the other.
Which standards and test methods are quoted for it?
These:
- ASTM D638
- ASTM D2671
- ASTM D2240
- ASTM D570
- ASTM D149
- ASTM D257
- ASTM D150
- IEC 216
- ESI 09-11
- IP68
