g. Pipe Thread Tightening Procedures.
WARNING
Adhesives, solvents, and sealing compounds can burn easily, can give off harmful vapors
and are harmful to skin and clothing. To avoid injury or death, keep away from open fire
and use in a well-ventilated area. If adhesive, solvent, or sealing compound gets on skin or
clothing, wash immediately with soap and water.
CAUTION
Use sealing compound sparingly and only on male threads. Do not apply compound on first
two threads to avoid contamination of system from compound. Do not apply compound to
hose connections or fittings with preformed packings. Damage to equipment may result.
(1) Coat threads of male fitting with sealing compound, sealant, or adhesive as indicated in each
maintenance task.
(2) Position male fitting on female fitting finger-tight.
(3) Scribe alinement mark on both fittings.
CAUTION
·
It may be necessary to tighten fitting slightly more or less than 2 1/2 turns to match
position noted prior to removal. Do not loosen fitting to arrive at proper position or
a leak may occur.
·
Over-tightening may cause pipe fitting to deform and damage to the joining fitting,
flange or component.
(4) Tighten male fitting 2 1/2 (3 maximum) full turns past hand-tight position.
