Face Seal Fittings Assembly & Installation - All Pressure Applications
Face Seal O-Ring to Stud End Installation
1. Inspect the fitting surfaces. They must be free of dirt and defects.
2. Inspect the O-ring. It must be free of damage and defects.
3. Lubricate the O-rings and install them into the groove using petroleum jelly to hold them
in place.
4. Push the O-ring into the groove with petroleum jelly so that the O-ring is not displaced
during assembly.
5. Index any angle fittings and tighten by hand, pressing the joint together to ensure that the
O-ring remains in place.
6. Tighten the fitting or nut to the torque value shown on the chart per dash size stamped on
the fitting. DO NOT allow hoses to twist when tightening fittings.
