Assembly Instructions for Ensuring Leak-Free O-ring Face Seal Fittings

- Jan 18, 2019 -

No matter what type of port, tube or hose ends your fittings have, it's important to know and use the proper assembly and installation steps. Today we are talking about O-ring Face Seal (ORFS) fittings. The face of the ORFS tube end has a soft seal in the captive o-ring groove (CORG). When the fitting is assembled properly this seal is compressed in the CORG, which is a precision machined groove in the fitting body face, to form a leak tight seal. This makes proper assembly key to ensuring leak-free O-ring face seal connections in your system.

Step 1: Inspect the tube end for a O-ring. 
Start by inspecting the ORFS fittings to make sure that the O-ring is properly installed in the groove (CORG). If an O-ring is not present, you will need to properly install one before moving to the next step. 

Step 2: Mate the fitting face and connection.
Place the flat face of the mating connection against the fitting face so that it makes complete contact with the O-ring. 

Step 3: Thread and torque.
Thread the nut onto the fitting body by hand. Then tighten it to the recommended torque values.
