Parker 62AB-4 Compression Tube Union Brass 400 Psi

Product Description

The PARKER 62AB-4 is a brass compression tube union designed to join two compression-end tubing runs in a single inline fitting. It provides a leak-resistant mechanical connection without soldering or flaring, making it a fast, reliable choice for brake line, fuel line, and fluid system repairs in mobile and stationary applications. The fitting is rated to 400 psi maximum working pressure and carries both D.O.T. FMVSS571.106 and SAE J246 certifications, confirming it meets federal and industry standards for automotive and fluid-transfer service. Licensed plumbers, fleet mechanics, and hydraulic technicians are the typical installers.

The 62AB-4 is suited for residential, commercial, and fleet applications where a union connection is needed in a compression-style tubing system. Its temperature range of -65 degrees F to 250 degrees F makes it viable in both cold-climate outdoor installations and under-hood or mechanical-room environments. The brass construction resists corrosion in wet or humid conditions, and the compression-by-compression end configuration allows it to be installed on existing tubing without cutting threads or applying heat.

Key Features

• Compression x compression ends for tool-accessible, no-solder installation
• Rated to 400 psi maximum working pressure
• Operates across a wide temperature range: -65 degrees F to 250 degrees F
• Brass construction for corrosion resistance in fluid and brake line service
• Certified to D.O.T. FMVSS571.106 and SAE J246 standards
• Inside diameter of 0.189 inches for accurate tubing fitment

Compatibility

Designed as an OEM-style replacement or service fitting for compression-end tubing systems meeting D.O.T. FMVSS571.106 and SAE J246 specifications.

Installation Notes

Installation is typically performed by licensed mechanics, plumbers, or fluid-system technicians. Shut off all pressure and depressurize the line before disassembly. Ensure tubing ends are cut cleanly and squarely and are free of burrs before seating compression ferrules. Do not overtighten compression nuts, as brass fittings are susceptible to ferrule deformation under excessive torque.
