PSI FlangeMate® Non-Isolating Sealing Gasket
With a metal retainer, the FlangeMate® provides superior hoop strength and positive assurance against gasket blowout. In addition, the FlangeMate® metal-to-metal contact between flange faces and the metal retainer makes it impossible to damage the gasket by over-torquing during installation. This also eliminates the need for gauge rings and other devices and methods to assure the correct torque for a positive seal.
The FlangeMate® gasket concentrates the total compressive load of a flange face on the sealing elements to produce a seal with a higher sealing load per square inch than any other gasket. Sealing elements may be made from any compressible material while retainers may be fabricated from any formable metal.

How The Seal Functions
The flange faces come into contact with both the sealing elements and the metal retainer. This initiates the sealing process, and results in the highest possible compressive load on the seals after the flange has been fully tightened.
The flange faces have reformed the metal retainer to encapsulate the sealing elements within grooves which controls the cold flow characteristics of the sealing material. The high compressive load developed by the tightened flange is concentrated on the seals. Over-torquing is impossible because of the metal-to-metal contact between the retainer and the flange faces.
The gasket retainer extends out to the I.D. of the bolt circle.
The FlangeMate® is available only as an “F” style gasket.
