Parker 62AB-6 Compression Tube Union Brass 400 Psi

Product Description

The PARKER 62AB-6 is a brass compression tube union designed to join two compression-end tubing runs in a single inline fitting. It creates a leak-resistant, removable connection without soldering or flaring, making it a practical choice for plumbing, refrigeration, pneumatic, and fluid-transfer lines where service access may be needed. The fitting is rated to 400 psi maximum working pressure and carries DOT FMVSS571.106 and SAE J246 certifications, confirming it meets federal motor vehicle safety standards and SAE hydraulic fitting specifications. Licensed plumbers, HVAC technicians, and fleet-maintenance professionals install this fitting in both new construction and repair applications.

This union is suited for residential and commercial plumbing, HVAC refrigerant tubing, pneumatic control lines, and automotive or fleet brake and fuel line repairs where DOT-rated compression fittings are required by code or specification. The 0.314-inch inside diameter accommodates standard tubing sizes used across these trades. The brass construction resists corrosion in wet and mildly corrosive environments and handles a wide service temperature range from -65 degrees F to 250 degrees F, making it viable in both indoor mechanical rooms and under-vehicle routing.

Key Features

• Compression x compression end connections — no soldering, brazing, or flaring required
• 400 psi maximum working pressure rating
• Brass construction for corrosion resistance and durability
• DOT FMVSS571.106 certified for use in motor vehicle brake and fuel line systems
• SAE J246 compliant for hydraulic and fluid-transfer fitting applications
• Wide temperature range: -65 degrees F to 250 degrees F

Compatibility

Designed as an OEM-style replacement or new-install compression union for tubing lines with a 0.314-inch inside diameter in plumbing, HVAC, pneumatic, and DOT-regulated automotive fluid systems.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified fleet-maintenance mechanics depending on the application. Shut off system pressure and bleed lines before disassembling or installing any compression fitting. Ensure tubing ends are cut square and deburred before seating into the fitting body to achieve a proper seal. Verify that applicable codes — such as IPC for plumbing or DOT FMVSS571.106 for vehicle systems — are met for the specific installation environment.
