How to Install Compression Type Fittings

Special Instructions

WARNING

A sudden release of air pressure can cause personal injury or damage to equipment. To prevent injury or equipment damage, exhaust the vehicle air tanks

Small air lines are available in 1/8" or 5/32" sizes. Make sure 1/8" air lines are used with 1/8" fittings and 5/32" air lines are used with 5/32" fittings. Mixing sizes can cause air leaks or damage to fittings.

Procedure -

1. Check the threads of the fitting for thread sealant. If no sealant is present, apply Eaton® Fuller® thread sealant #71205 or equivalent.

2. Install the fitting.

Note: Do not overtighten the nut. Overtightening can compress the collet too much and cause an air line restriction.

3. Install the air line, collet, and nut. If installing a new fitting, place the collet in the fitting and loosely install the nut. (Do not tighten the nut yet.) Insert the air line through the nut and into the collet. Tighten the nut as usual.

4. Enable the vehicle air system. Allow the air tanks to pressurize, and check for leaks. Repair as necessary.
