2.8.5 Assembly Instructions for 45° SAE Flare
Fittings
1. Inspect the flare for obvious visual squareness and
concentricity issues with the tube OD. Ensure that
surface is smooth, free of rust, weld and brazing splatter,
splits, dirt, foreign matter, or burrs. If necessary, replace
fitting or adapter.
NOTICE
DO NOT force a misaligned or short hose/tube into
alignment. It puts undesirable strain onto the joint
eventually leading to leakage.
2. Align tube to fitting.
3. Tighten fitting by hand until hand tight.
NOTICE
The torque method should NOT be used on lubricated or
oily fittings. No lubrication or sealant is required. The
lubrication would cause increased clamping force and
cause fitting damage.
Torque fitting to value listed in below table while using the
Double Wrench Method outlined in this section.
