2.3.5 Flat-Face O-ring Fittings
When the vehicle leaves the factory, it is equipped only
with straight thread o-ring fittings. Customer-added
accessories may differ; therefore, consult the manufac-
turer's product literature for information.
Improper assembly of this type of joint will result in a leaking
joint. Under tightening will result in the joint loosening dur-
ing normal use. Foreign material on either sealing surfaces
will cause damage to one or both mating parts when the
joint is tightened, resulting in a leaking joint. The absence
of the fitting o-ring will cause the joint to leak.
1. Verify that both threads and sealing surfaces are
free of burrs, nicks, scratches, and any foreign
material.
2. Inspect the male fitting for the presence of the o-ring
seal. Replace the o-ring if missing or damaged.
3. Place the flat surface of the female connector in full
contact with the o-ring in the male connector.
4. Finger tighten the nut onto the fitting.
5. Hold the fitting in the desired position, for hoses and
swivel fittings, use a second wrench to keep the
female connector from moving during tightening.
