Parker 265AB-10 Compression Tube Union Brass 400 Psi

Product Description

The PARKER 265AB-10 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 and suited for service from -65 degrees F to 250 degrees F, this fitting handles a wide range of fluid and gas transfer applications. The 0.533-inch inside diameter accommodates standard half-inch tubing. Plumbers, HVAC technicians, and mechanical contractors install this type of union when a removable, leak-tight tube joint is needed without soldering or threading the line.

This compression union is appropriate for residential and light commercial plumbing, refrigeration, and pneumatic tubing runs where both ends of the line accept a compression-style connection. The all-brass construction resists corrosion in water, air, and many common fluid service environments. It is a practical choice for equipment connections, instrument lines, and process tubing where periodic disassembly may be required.

Key Features

• Compression x compression end connections on both sides for tool-accessible disassembly
• 400 psi maximum working pressure suits a broad range of plumbing and pneumatic service
• Operating temperature range of -65 degrees F to 250 degrees F
• 0.533-inch inside diameter sized for standard half-inch tubing
• Brass construction provides corrosion resistance across common fluid and gas media

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compression tube systems requiring an inline union connection at standard half-inch tubing size.

Installation Notes

This fitting is installed by licensed plumbers or qualified mechanical technicians. Always depressurize and drain the line completely before removing or installing any compression fitting. Hand-tighten the compression nut first, then advance with a wrench — do not overtighten, as brass compression fittings are susceptible to sleeve deformation. Verify installation compliance with applicable local plumbing codes and IPC guidelines.
