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.
