IsoGuard™ is NSF 61 Certified for use with potable water.

The ISOGUARD™ sealing/isolating gasket system is designed for applications where electrical flange isolation and corrosion control are required on pipes containing potable water up to 302°F(150°C). Available for flat face, raised face and ring type joint flanges from 1/2” to 120” (and corresponding API and DN diameters), ANSI 150-1500#, API 2-5K and PN 20-250, the ISOGUARD™ gasket is an engineered value added solution for trouble free operation. The ISOGUARD™ sealing/isolating gasket system consists of a retainer with an incline-plane seal groove geometry and rectangular sealing element “Quad” ring. This design guarantees low bolt load requirements and high sealing reliability. In fact, it´s based on an industry proven design that has been used successfully for over 30 years for a wide variety of applications including sealing volitale fluids in high pressure pipelines.
