Isomate by Lamons

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.

CONFIGURATIONS FOR GASKET TYPE AND SLEEVE AND WASHER SETS


Type "E" Gasket Fits over the bolt holes and extends to the O.D. of the flange to assist contractors as the bolt holes automatically center the gasket. Provides excellent protection against shorting out of the corrosion mitigation hardware.	Type "F" Gasket Fits within the bolt hole circle of the flange and extends to the I.D. of the bolt circle providing good protection against shorting out of the corrosion mitigation hardware.	"E" or "F" Type Gaskets The Isomate gasket is available in a Type "E" or "F" configuration to accommodate all your sealing/isolating needs.
