      Product Description

      Heat Shrink Coupler is a Tubing used for jointing the posttensioning ducts to ensure leak tightness of connections between two consecutive portion of duct.

      These tubes are manufactured from high quality Cross-linked Polyolefin material. Hot melt adhesive lining provides 100% sealing according to IP 68 (Ingress Protection). Heat Shrink Couplers ensure a tight seal around the pre-stressing duct connections.

      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.
