The Isoguard sealing/isolating gasket system is designed for general 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 392ºF (200ºC). Available for flat face, raised face and ring type joint flanges, this system consists of a retainer with an incline-plane seal groove designed to optimize each seal’s elastic memory, in conjunction with a proven rectangular sealing element (“Quad” ring). This design guarantees low bolt load requirements and high sealing reliability. IsoGuard systems are available with a variety of retainers and seal elements.
The Isoguard kit also includes sleeves and washers to streamline the ordering process of parts needed for a fully isolated flanged connection.
