Parker 62NBH-4 Compression Tube Union Brass 150 Psi

Product Description

The PARKER 62NBH-4 is a brass compression tube union designed to join two compression-end tube lines in a single, inline connection. Rated to 150 psi maximum working pressure and capable of handling temperatures from -40 degrees F to 200 degrees F, this fitting suits a wide range of fluid and gas plumbing applications. The all-brass construction provides corrosion resistance and durability in both residential and light commercial environments. Plumbers, HVAC technicians, and refrigeration mechanics install this type of fitting where a reliable, leak-resistant tube-to-tube union is required without soldering or welding.

This fitting is suited for use in potable water lines, refrigeration tubing runs, pneumatic control lines, and general fluid transfer systems where compression-style end connections are specified. Its compact form factor makes it practical in tight spaces or panel installations. The 0.137-inch inside diameter accommodates standard small-bore tubing in residential and commercial plumbing and HVAC control applications.

Key Features

• Compression x compression end connections for tool-accessible, no-solder installation
• Brass construction offers corrosion resistance for water, air, and compatible fluid service
• Rated to 150 psi maximum working pressure
• Operating temperature range: -40 degrees F to 200 degrees F
• 0.137-inch inside diameter for small-bore tubing applications
• Lightweight at 0.1 pounds — practical for overhead or confined installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for small-bore compression tube systems in residential and commercial plumbing, HVAC, and pneumatic control applications.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician following applicable IPC or IFGC requirements. Shut off and depressurize the line before disassembly or fitting installation. Ensure tubing ends are cut cleanly and deburred before seating the compression ferrule to prevent leaks. Do not overtighten compression nuts — hand-tight plus a controlled turn with a wrench is the standard approach for brass compression fittings.
