IsoJoint is a true monolithic isolating joint. The most up-to-date, patented joint on the market, IsoJoint does not depend on the use of isolating sleeves and washers for bolts nor isolating gaskets or O-rings between flanges. Why? These isolating gasket kits require a critical, even surface and proper placement of a sealing element to provide regular and variable crushing and must be maintained over the life of the isolator. External pressure causing an uneven load on the flange area can result in loss of isolating properties as well as the transported fluid.
