EXPANDED PTFE TUBES 70 % PTFE & 30% GRAPHGITE (On Depend).

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 refight after installation.
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.
