Covalence HTTE

Quick Overview

Heat-shrinkable molded part for the corrosion protection of house connection tees. HTTE House Tap Tee. Construction: Two-layer system First layer: Copolymer adhesive Second layer: Thick walled, radiation cross-linked, high density polyethylene. HTTE is a heat-shrinkable molded part, pre-shaped to encapsulate house connection weldon tees. The thick-walled, highly expanded molded part is coated with a specially formulated hot-melt adhesive for this application. The adhesive melts during installation and, under pressure from the shrinking sleeve, is forced into surface irregularities, thus providing an excellent seal. The HTTE part can be delivered with or without a cap. To prevent corrosion of the service pipe where the house connection is made, the use of a compatible PERP patch or WPC heat-shrinkable wraparound sleeve is recommended. HTTE is installed using regular propane gas torches. The installation is carried out directly on the cleaned and preheated substrate. The part is positioned on the branch-off pipe and slid over the tee-piece to be protected. Using a torch, the HTTE is then shrunk in place. During recovery, the adhesive softens and flows to form a tight bond with the substrate. The bond strength builds up during cool down and is fully retained after completion of the job. Benefits and features of the product include no primer required: no drying time and easy application, pre-shaped mold system: makes installation easy and provides accurate protection, controlled high wall thickness: provides accurate & reliable protection, and HTTE-kit available: an all-in-one product to protect the house tap tee. HTTE type products are available: as a molded part with or without cap and as a kit (P-kit and G-kit). P Kit contains PERP patch + S1052 mastic strip and G Kit contains WPC-C30 unisleeve.
