FLANGE INSULATION KITS
FOR CATHODIC PROTECTION

INSULATION KIT TYPES

TYPE E (FULL FACE GASKET)

TYPE F (RING GASKET)
This gasket kit provides complete protection of both flange faces. The gasket has same outside diameter of flanges. This feature will prevent collection of foreign matter between the flange faces to ensure complete cathodic isolation.

This gasket is manufactured to fit only the raised face surface of the flanges. Outside diameter of the gasket is designed to be slightly less than the inside diameter of the bolt circle. It is recommended that the flanges be wrapped to prevent foreign material from "shorting out" the flanges.

 

TAG-SEAL TYPE D (Gaskets)
This gasket has a sealing element bonded in both faces of the gasket and can be furnished in Type E full face Gasket or Type F ring gasket. TAG-SEAL gives the resilience of an O-ring and maintains constant contact with the flange face. Gaskets are offered in any of the materials listed on specification sheet with Nitrile, Viton, Silicone, Teflon or expanded Teflon as the sealing element. To fit RTJ flanges, we offer CE and LE grade phenolic and glass filled Teflon.
