Tightening High-Pressure Fittings
1. Use your fingers to tighten the fitting bolt as tight as you can.
2. After finger-tightening, use a wrench to tighten the fitting an additional
three-quarter turn (270 degrees).
3. If leaks occur, replace the fitting bolt (P/N 074449), ferrule (P/N 074373),
and tubing.
1.6.3
Cutting Non-Capillary Tubing
If a connection does not require precision cut capillary tubing, you can use a
tubing cutter to cut tubing to the required length. Make sure the cut is at a
right angle to the length of the tubing and there are no nicks or burrs on the
end. A tubing cutter (P/N 049584) is included in the DC Ship Kit
(P/N 072011, standard DC; P/N 22171-62000, low-temperature DC). Refer to
the instructions provided with the cutter.
