NOTE:
Ensure the threads and sealing surfaces are free from nicks, burrs, scratches or any for-
eign material. Lubricate the o-ring with a light coat of oil. To tighten adjustable o-ring fit-
tings, hold the fitting and tighten the nut. To tighten non-adjustable o-ring fittings, tighten
the fitting. When tightening together fittings with dissimilar coatings, torque to 115% of
maximum recommended torque value for a given size.
