Assembly instructions for Adjustable Port End
(BSPP) Fittings
1. Inspect components to ensure that male and female
threads and surfaces are free of rust, splits, dirt, foreign
matter or burrs.
2. If o-ring is not pre-installed, install proper size, taking
care not to damage it. See O-ring Installation (Replace-
ment) for instructions.
CARE TO BE TAKEN WHEN LUBRICATING O-RING. AVOID ADDING OIL TO THE
THREADED CONNECTION OF THE FITTING. THE LUBRICATION WOULD CAUSE
INCREASED CLAMPING FORCE AND CAUSE FITTING DAMAGE.
3. Pre-lubricate the o-ring with Hydraulic Oil.
4. For Non-Adjustable Fittings and Plugs, thread the fitting
by hand until contact.
5. For Adjustable fittings, refer to Adjustable Stud End
Assembly for proper assembly.
