Compression Fittings

•Typical Application

Instrumentation, hydraulic and pneumatic systems.

•Pressure

Working pressure up to 2000 PSI with a 4:1 safety fac-

tor depending on tube size. When using plastic tubing,

use the working pressure for type used.

•Vibration

Fair resistance - use long nut when greater vibration

resistance is needed.

•Temperature Range

-65

operating pressures. (Refer to tubing temperature

range.)

•Material

CA360 Brass for barstock fittings.

CA377 Brass for forged fittings.

•Used With

Aluminum, copper, brass and plastic tubing. Plastic tub-

ing requires insert. Not recommended for steel tubing.

•

Tolerance

+/- .02 on all dimensions. Dimension data can change

without notice. Please call us when dimensions are

critical.

• Conformance

Meets specifications and standards of ASA, ASME and

SAE.

•Assembly Instructions

1- Cut tubing to desired length.

2- Slide nut and then sleeve on tube. Threaded end

“A” of nut must face toward fitting.

3- Insert tubing into fitting body. Be sure tubing is

bottomed on fitting shoulder.

4- Lubricate threads and assemble nut to fitting body.

5- Tighten nut hand tight. From that point, tighten

with a wrench the number of turns indicated in the

chart below.

•

“L” at the end of a Part#means Light Pattern

-These

fittings are completely interchangeable with full pattern

fittings, but have been modified in some way. This

modification is usually in the length of the pipe threads.

Used in plumbing and light industrial applications.
