Heat Shrinkable Coupler
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 high quality Cross-linked Polyolefin material. 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.
Features & benefits :
- Easy & Quick Installation. No special skill required.
- High resistance to Impact & Abrasion.
- Suitable for Wet and Dry underground conditions.
- Joint in-line with pipe.
- Superior elastomeric characteristics allows better conformance over irregular contours.
- High Shrink ratio (3:1) helps to reduce the stock requirements with few sizes covering greater pipe application range.
- Resistant to Heat, UV rays, Vibration, Sand-blasting & Harsh Industrial conditions.
- Customized dimensions, length & colour available.
