XLDS Flashcards
The O‐ring sealed fittings that connect the HP air supply to the RDC are designed to provide an air‐tight seal with minimal tightening of the fitting. Fittings should be installed hand‐tight and then lightly snugged using the effort of two fingers on a wrench (no more than a ___ turn past hand‐tight).
