Parker 60AB-4 Compression Tube Sleeve Brass 400 Psi

Product Description

The PARKER 60AB-4 is a brass compression tube sleeve designed to secure tubing in compression-style fittings across hydraulic, pneumatic, and fluid transfer lines. The sleeve seats against the fitting body as the nut is tightened, creating a leak-resistant mechanical connection without flaring or soldering. With a 0.255-inch inside diameter and a maximum working pressure of 400 psi, it suits a wide range of small-bore tubing applications. The part meets D.O.T. FMVSS571.106 and SAE J246 standards, confirming suitability for brake and fuel line service in mobile and industrial environments. Plumbers, hydraulic technicians, and fleet mechanics are the primary installers.

The 60AB-4 sleeve is used in residential and commercial plumbing, mobile equipment brake lines, and industrial fluid systems where compression-style tube connections are specified. Its rated temperature range of -65 degrees F to 250 degrees F makes it suitable for both outdoor mobile applications in cold climates and moderate-temperature fluid lines. Typical installations involve small-bore copper, nylon, or poly tubing routed in brake, fuel, or instrumentation circuits where a reusable, tool-free tube connection is preferred over flared or soldered joints.

• Wide temperature range: -65 degrees F to 250 degrees F
• Meets D.O.T. FMVSS571.106 and SAE J246 standards for mobile equipment service

Compatibility

Designed as an OEM-style compression sleeve for use with Parker and other compression-style tube fitting bodies sized to accept a 0.255-inch inside diameter sleeve in brake, fuel, and fluid transfer line applications conforming to SAE J246 and D.O.T. FMVSS571.106.

Installation Notes

Installation is performed by plumbers, hydraulic technicians, or fleet mechanics depending on the application. Depressurize and drain the line completely before disassembling any compression fitting. Ensure tubing is cut square and deburred before inserting through the nut and sleeve. Overtightening the compression nut can deform the sleeve and compromise the seal — hand-tighten, then follow fitting manufacturer torque guidelines for the specific fitting body.
