Parker 62AB-8 Compression Tube Union 1/2 Inch Brass

Product Description

The PARKER 62AB-8 is a brass compression tube union with compression fittings on both ends, designed to join two sections of 1/2-inch OD tubing in a single inline connection. It carries a maximum working pressure of 400 psi and handles temperatures from -65 degrees F to 250 degrees F, making it suitable for a wide range of fluid and pneumatic line applications. This union meets D.O.T. FMVSS571.106 and SAE J246 standards. It is installed by licensed plumbers, HVAC technicians, and fluid-system mechanics who need a reliable, leak-free tube connection without soldering or flaring.

The 62AB-8 is suited for use in hydraulic brake lines, pneumatic control lines, refrigeration tubing runs, and general fluid transfer systems where a straight union connection between two 1/2-inch OD compression tubes is required. Its brass construction resists corrosion in both wet and dry service environments. The fitting is appropriate for residential and light commercial applications and is commonly used in mobile equipment, HVAC refrigerant lines, and plumbing utility connections where DOT and SAE compliance is required.

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 1/2-inch OD compression tubing that require a straight union connection compliant with D.O.T. FMVSS571.106 and SAE J246.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanic. Depressurize and isolate the line completely before disassembling any fitting. Hand-tighten the compression nuts first, then snug with a wrench — do not overtighten brass compression fittings, as excess torque can deform the ferrule and cause leaks. Verify the tubing end is cut square and deburred before seating it in the fitting body.
