E.
Dry with air as described in previous caution or by heating at a temperature of 250° to 300° F for one
half hour.
— Note —
Solvents can be reused provided they do not become excessively contaminated with
oil. This condition can be determined by thoroughly evaporating 100 milligrams of the
liquid in a glass dish of a determined weight. Evaporation may be accomplished by
heating the dish at 20°F for one hay hour. If after evaporation and cooldown, the
residue exceeds 100 milligrams in weight, the solvent shall not be reused
3. Method 111.
A.
Flush with hot inhibited alkaline cleaner until free from oil and grease.
B.
Rinse thoroughly with fresh water.
C.
Dry thoroughly with a stream of clean air as described in the previous caution, or by heating 250° to
300° F for one half hour minimum.
4.
After cleaning. all tubing must be protected by caps, plugs, and/or plastic bags.
— CAUTION —
DO NOT USE ADHESIVE TAPE ON OXYGEN COMPONENTS FOR
AT TACHING OR SECURING PROTECTIVE COVERINGS. USE LUDLOW
NO. 6 WAXED LACING TWINE OR TIE WRAPS
5. Before reinstallation make sure fitting, tube, and fixture threads are in good condition and that the cones do
not exhibit pitting or disfigurement.
SWAGELOC FITTING INSTALLATIONS. (Refer to Figure 35-5.)
— Note —
The high pressure line fitting at the regulator should be tightened until it bottoms
Make sure to use teflon tape on all male pipe threads.
1. For swageloc fittings not preswaged or for in-aircraft installation, proceed as follows:
A.
Turn the fitting nut onto the fitting finger tight, and insert the tube until it bottoms firmly on the
shoulder in the fitting.
B.
Tighten the nut with a wrench until the tube will not turn by hand.
C.
Mark the nut at the six o'clock position.
D.
Hold the fitting body steady with a backup wrench and tighten as follows:
(1). On tubing with a diameter bigger then 3/16 inch, tighten 11/4 turns (to the nine o'clock position).
(2). On tubing of 1/16, 1/8, and 3/16 inch diameter tighten only 3/4 turn.
E.
If nut and tube must be disconnected from the fitting reconnect by seating the tube on the shoulder of
the fitting and tightening the nut finger tight. Follow up by tightening the nut with a wrench, one-
quarter turn (if absolutely necessary the original 11/4 or 3/4 tight position) and then snug with wrench.
