BRASS COMPRESSION FITTINGS

BRASS COMPRESSION FITTINGS - ASA, ASME, SAE

Compression Fitting Thread Diagram

TYPICAL APPLICATION: Use with copper, aluminum and thermoplastic tubing. Not recommended for steel tubing. Manufactured for low and medium pressure tubing connection work where excessive vibration or tube movement is not involved. Not recommended for application using gaseous media.

MATERIAL: CA360 Brass for barstock fittings. CA377 Brass for forged fittings.

CONFORMANCE: Meets specifications and standards of ASA, ASME and SAE.

TEMPERATURE RANGE: 65F to +250F (-53C to +121C) range at maximum operating pressures. (Refer to tubing temperature range.)

VIBRATION RESISTANCE: Fair resistance - use long nut when greater vibration resistance is needed.

PRESSURE: For working pressures at 73F

LIGHT PATTERN "L" FITTINGS: 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.

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.
