E. Identification of Fluid Lines (Refer to Figure 4, page 20-5)
Aircraft fluid lines are identified by color code markers, words and geometric symbols. The markers
identify each line`s function, content, primary hazard, and the direction of fluid flow.
Most fluid lines are marked with 1 inch tape or decals. Paint is used on lines in the engine induction
system.
Certain lines may also be identified as to the specific function within a system. For example: DRAIN,
VENT, PRESSURE or RETURN.
Lines conveying fuel may be marked FLAM. Lines containing toxic materials are marked TOXIC.
Line containing physically dangerous materials, such as oxygen, nitrogen, or freon, are marked
PHDAN.
The aircraft and engine manufacturer is responsible for the
original
installation of identification
markers, Aircraft maintenance personnel are responsible for their replacement when it becomes necessary.
Tapes, paint, tags and decals are placed on both ends of a line and at least once in each compartment
through which the line runs. Identification markers are also placed immediately adjacent to each valve,
regulator, filter or other accessory within a line.
F, Flareless Tube Assemblies.
The use of flareless tube fittings eliminates all tube flaring. An operation, referred to as presetting, is
necessary prior to installing a new flareless tube assembly. Presetting is performed as follows:
(1) Cut tube to correct length. Ensure ends are perfectly square. Deburr inside and outside of tube.
Slip nut, then sleeve, over the tube. (refer to Figure 5, step 1, page 20-6)
(2) Lubricate fitting and nut threads as specified in table contained in Figure 5, page 20-6.
(3) Place fitting in a vise (refer to Figure 5, step 2, page 20-6). Hold tubing firmly and squarely on
seat in fitting. (Tube must bottom firmly in the fitting.) Tighten nut until cutting edge of sleeve
grips tube. This point is determined by slowly turning tube back and forth while tightening nut.
When tube no longer turns, nut is ready for final tightening.
(4) Final tightening depends upon type and size of tubing. On aluminum alloy tubing up to and includ-
ing half inch outside diameter, tighten nut from 1 to 1-1/6 turns. On aluminum alloy tubing over
half inch outside diameter, or steel tubing, tighten nut from 1-1/6 to 1-1/2 turns.
(5) After presetting the sleeve, disconnect tubing from fitting and check the following points (refer to
(a) Tube extends 3/32 to 1/8 inch beyond sleeve pilot to prevent blow off.
(b) Sleeve pilot contacts tube. A maximum clearance of 0.005 inch for aluminum alloy tubing, or
0.015 inch for steel tubing, is acceptable.
(c) A slight collapse of tube at sleeve cut is permissible. No movement of sleeve pilot, except
rotation, is permissible.
