Durlon® iGuard™ 9000

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™ 9000: The iGuard™ 9000 style isolation gasket is manufactured from 3mm (1/8”) thick genuine Durlon® 9000 glass filled PTFE gasket material to improve sealability in critical service chemical environments from pH 0-14 and other aggressive media and from temperatures between -73°C (-100°F) to 232°C (450°F). This design makes the iGuard™ 9000 ideal for cryogenic, petrochemical, pharmaceutical, semiconductor manufacturing, and food and beverage manufacturing applications in ANSI Class 150 and 300 or international equivalents and comes in sizes from NPS ½” (DN 25) to NPS 144” (DN 3600) in Type E (full face) or Type F (raised face) configurations. These kits come standard with one iGuard™ 9000 gasket, two isolating PTFE washers, two SAE zinc plated steel backup washers, and one PTFE sleeve tube for every bolt/stud.

Durlon® iGuard™ flange Isolation Kits are available for the following applications: Oil & Gas, Pulp & Paper, Petro Chemical, Refining, Water & Wastewater, Food & Beverage, Marine, Aerospace and LNG.
The standard iGuard™ kit consists of a gasket, isolating washers and isolating bolt/stud sleeves. The gasket/carrier can be constructed of plain phenolic, neoface phenolic, epoxy glass (G-3, G-10 or G-11), epoxy glass (G-10) bonded to 316SS core, Durlon® 8400, Durlon® 8500 or even Durlon® 9000. In gaskets with phenolic or glass carrier rings, the double-ogre sealing element provides a reliable concentrated unit load on the flanges using the lowest torquing conditions possible. For other styles, a spring energized PTFE sealing element is used.
