Product Description
Heat-shrinkable End Cap
Heat-shrinkable reducer sleeves
Reducer sleeves also called End Cap, it is a heat-shrinkable, end cap for pre-insulated pipes operating up to 90°C (194°F).
Water proof end cap is made from a specially formulated cross-linked polymer and is fully lined with a high performance, mastic adhesive. This combination provides a high quality, reliable system for the sealing protection of pre-insulated pipes.
• Designed to provide a water tight seal and prevent water access to the exposed insulation at the weld joint area
• Shrinks to conform to the profile of the insulated pipe
• Protects the insulation during storage and transportation
• Available in a full range of sizes
• Tubular configuration for quick and easy installation
• Excellent bonding compatibility to common pipe coatings
