Durlon® iGuard™ CS

Durlon® iGuard™ flange Isolation and sealing systems consist of all the necessary components to seal and electrically isolate between flanges, from general service to severe service applications. Gaskets are available in Raised Face (Type F), Full Face (Type E) and RTJ (Type D) flanges from NPS 1/2” (DN15) to NPS 144” (DN 3600) or equivalent, to meet all international piping sizes.

iGuard™ CS: The iGuard™ CS style isolation gasket is manufactured from 3mm (1/8”) thick Nema grade G-10 glass epoxy material bonded to a 316 stainless steel internal core with a spring energized PTFE sealing element to prevent cold flow in critical service applications under continuous reciprocation movement or internal pressure surges at elevated temperatures. This design makes the iGuard™ CS ideal for API Class 15,000 and ANSI Class 600, 900, and 2,500 flange applications. This kit comes standard with one iGuard™ CS gasket, two isolating Nema grade G-10 washers, two SAE zinc plated steel backup washers, and one Nema grade G-10 sleeve tube for every bolt/stud. Maximum pressure class - 2,500# ANSI, 15,000#API.
