Flared Fittings Tightening Procedure
1. Screw the ttings together nger tight. Then, using the
proper size wrench, rotate the tting 2-1/2 hex ats.
IMPORTANT
Flare seat MUST NOT rotate when
tightening. Only the nut should turn.
2. Back the tting off one full turn.
3. Again tighten the ttings nger tight; then using a
wrench, rotate the tting 2-1/2 hex ats. This will
complete the tightening procedure and develop a
pressure tight seal.
CAUTION
Overtightening will damage tting resulting in
uid leakage.
