Description
The Isomate™ sealing/isolating gasket is designed for basic applications where electrical flange isolation and corrosion control are required on pipes containing water/wastewater, gas, natural gas, oil and other hydrocarbon based medias up to 175ºF(79ºC). Available for flat face and raised face joint flanges from 1/2" to 24", ANSI 150-300#. The Isomate gasket is an economical solution for basic performance. Isomate sealing/isolating gasket consists of a Phenolic retainer faced on both sides with Nitrile rubber material.

Temperature - Operating |
-65°F (-54°C) to +175°F (+79°C) |
NOTE: Operating Temperature for Gaskets and Flange Isolation Kits is based off the Gasket Retainer Temperature. Seal element temperature does not dictate the min. and max. gasket operating temperature.
Features
The industry has improved sealing technology in retainer type gaskets with engineered seal elements and groove designs. Defender™ and IsoGuard™ sealing systems should be reviewed, specified and used when a long-term maintenance-free solution is necessary.
