Parker 165CA-10 Brass Compression Tube Union

Product Description

The PARKER 165CA-10 is a brass compression tube union designed to join two compression-end tube lines in a single inline fitting. It provides a leak-resistant mechanical connection without soldering or threading the tube ends, making it a reliable choice for hydraulic, pneumatic, and fluid-transfer applications. The fitting handles working pressures up to 650 psi and operates across a temperature range of -65 degrees F to 250 degrees F. Both ends accept standard compression-style tubing. Licensed plumbers, HVAC technicians, and fluid-system technicians are the typical installers.

This union fitting is suited for residential and commercial installations where a straight inline tube connection is needed between two compression-end lines. Common applications include refrigeration lines, hydraulic circuits, fuel systems, and instrumentation tubing runs where a removable, pressure-rated union joint is preferred over a permanent brazed or soldered connection. The compression-by-compression configuration allows the fitting to be disassembled and reassembled during service without replacing the tubing.

Key Features

• Brass construction for corrosion resistance in fluid and gas service
• Compression x Compression end connections on both sides for tool-assisted tube retention
• Rated to 650 psi maximum working pressure
• Wide service temperature range of -65 degrees F to 250 degrees F
• Inline union design allows line disassembly during maintenance without cutting tubing
• NPTF thread standard where applicable

Compatibility

Designed as an OEM-style replacement or service fitting for compression-end tube systems requiring a straight union connection in plumbing, HVAC, refrigeration, and fluid-transfer assemblies.

Installation Notes

Installation of compression fittings is typically performed by licensed plumbers or HVAC technicians. Shut off all system pressure and depressurize the line before disassembly or installation. Ensure tubing ends are cut square and deburred before inserting into the compression sleeve to achieve a proper seal. Do not overtighten the compression nut, as brass fittings can distort the ferrule if excess force is applied.
