Connect hose (disconnected from C-5) to threaded end of adapter. Hand-tighten.
Check gasket removed from C-6 for damage. If gasket damaged, notify your supervisor. Apply thin coat of
silicone lubricant (item 5, appendix D) to gasket lips and outside of gasket.
Place gasket over other end of adapter, being sure it doesn't overhang end of connection.
Align end of high pressure hose with adapter. Slide gasket to center position between adapter groove and
hose groove. No portion of gasket should overhang grooves.
Place grooved pipe coupling halves over gasket. Make sure grooved pipe coupling half keys are in grooves
on adapter and hose.
Install two bolts. Place nuts on bolts and hand-tighten.
Overtightening nuts may cause gasket to pinch. Tighten nuts only until grooved pipe coupling halves are
firmly together (metal-to-metal).
Tighten nuts alternately and equally until grooved pipe coupling halves are firmly together.
