Flexible Joints  
   
 

Fluid Conveying Products

 
 

Flexmaster joints are available in both standard and self restrained styles. The self restrained style has a stainless.steel gripping ring inside each gasket. This feature allows the joint to maintain a firm grip on the pipe or tube, preventing movement along the pipe or tube.

The barrelled, straight-through Flexmaster joints accommodate angular misalignment up to 4° per end. Tees, elbows, and crosses accommodate angular misalignment up to 2° per end.Flexmaster joints are designed for up to 300 psi (2.07 MPa) service, depending on application and size.

Flexmaster joints absorb vibration and are ideal for making quick connections and disconnections when repairing or dissembling a system. They can be furnished with several types of gasket compounds and sleeve material, including stainless steel for marine and corrosive applications.

Flexmaster joints are currently in use in thousands of applications throughout the world.
