Description:
Casing end seal is is a heat-shrinkable, wrap-around sleeve with a very high shrink ratio, specially developed for casing/service pipe sealing.The special adhesive inside the thick-wall assures an excellent bond between the sleeve and bare or pre-coated pipes.
Construction: Two-layer system:
First layer: Visco-elastic waterproof sealant.
Second layer: Radiation cross-linked, polyethylene backing.
Product features/benefits:
• 60% shrinkage ratio – conforms to high transitions Reduces inventory & logistics costs.
• Resists a wide range of environmental and mechanical forces Reliable, moisture-proof seal!
• Specially formulated sealant Ensures a strong bond & tight seal to virtually any substrate. Maintains its elasticity and sealing characteristics over a wide temperature range.
• Sealing adhesive automatically flows and repairs minor mechanical damages .Saves time.
• Usable also when service pipe is not concentric with the casing. Highly versatile.
• No special equipment required Makes installation fast and easy. Keeps installation costs low.
