100% pure expanded PTFE Sealants with self-adhesive film. It's an idea sealant for most pipe fitting and equipments flanges sealing
Extremely wide range of uses in:
* Low stress to seal requirements help protect flagile flange and delicate assemblies.
* Higher resistant to creep and cold flow when sealing of heat exchanger and no need to retight after installatioin.
* No precutting and no wasteful scrap saves time and money when sealing large equipment flanges.
* Since It's so versatile and inert to most chemicals. It's perfect for the most challenging chemical application.
* Ideal for large, complex or damages sealing surfaces due to its strong yet conformable nature.
* TOP SEAL is a UNICERSAL sealing material for valves; It servers as a flange gasket and box packing.
