SAE Flange

The four-bolt flange is a proven leak-free connection, especially suited for larger sizes. As a result, it has achieved worldwide acceptance. The connection's success is in its simplicity. It is a static face seal using a high durometer O-ring for the seal and clamps and bolts for the holding power.

This simple design provides several advantages over threaded port connections, such as NPT, SAE, BSPP, ISO 6149, etc., in larger sizes:

  • Ability to connect up to 5 inch O.D tube (code 61 only).
  • Up to 6000 psi capability through 2" size (code 62 only).
