Containment System Leaks
• Always leak check the system after servicing it. Use a leak-check liquid solu-
tion, or apply pressure and check for any drop over time – indicating a leak. Do
not apply more than 45 psig or component damage could result.
• Before disconnecting a compression fitting, first mark the fitting to show the
alignment of the fitting body and nut(s). When re-assembling, tighten the fitting
back to this original orientation, and then tighten slightly more to ensure a good
seal.
• If installing a new compression fitting, follow the Swagelok guidelines below:
o Ensure that tube end is pushed all the way to the stop inside the fitting
body.
o Tighten finger-tight.
o For 1/8” fittings, wrench-tighten an additional ¾ turn.
o For ¼” and 6 mm fittings, wrench-tighten 1-1/4 turns past finger-tight.
• When reassembling a sample cell, ensure than all screws are tightened suffi -
ciently to bring the cell pieces into contact (bottom out).
