Parker 62VL-6 Compression Tube Union 3/8 in Brass 400 Psi

Product Description

The PARKER 62VL-6 is a brass compression tube union designed to join two compression-end tube lines in a single inline connection. Rated to 400 psi maximum working pressure, this fitting handles a 3/8 inch outside diameter tube and is built from brass for reliable sealing in fluid and pneumatic systems. The union configuration allows two compression fittings to mate without requiring a wrench on the tubing itself, making it a practical choice for tight plumbing and instrumentation runs. HVAC technicians, plumbers, and fluid-systems installers use this type of fitting where a leak-free, repositionable tube joint is required.

This fitting is suited for residential and light commercial applications involving tubing runs in refrigeration, instrumentation, fuel, or hydraulic systems where working pressures remain at or below 400 psi. The compression-by-compression end configuration makes it appropriate for in-line repairs or extensions of existing tubing without soldering or flaring. Temperature service range extends from -30 degrees F to 275 degrees F, covering most standard HVAC and plumbing operating conditions.

Key Features

• Compression x Compression end connections — no soldering or flaring required
• 3/8 inch outside diameter tube sizing
• 400 psi maximum working pressure rating
• Wide temperature range: -30 degrees F to 275 degrees F
• Meets ISO 6149 and SAE J1926 standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/8 inch outside diameter compression tubing in plumbing, HVAC, refrigeration, or instrumentation applications.

Installation Notes

Installation is performed by qualified plumbers or HVAC technicians following applicable IPC and IFGC guidelines. Shut off and depressurize the system fully before removing any existing fittings or tubing. Ensure tube ends are cut square and deburred before seating into the compression fitting to achieve a proper seal. Do not overtighten compression nuts, as this can deform the ferrule and compromise the joint.
