Parker 165C-10 Compression Tube Union Brass Sae J-512

Product Description

The PARKER 165C-10 is a brass compression tube union designed to join two compression-end tube lines in a single in-line connection. Rated to 150 psi maximum working pressure and a temperature range of -65 to 250 degrees F, this fitting suits demanding fluid and gas plumbing applications where a leak-free, tool-assisted tube connection is required. The 13/16-18 thread size follows SAE J-512 standards, ensuring dimensional conformity with compatible compression fittings across the trade. Plumbers, HVAC technicians, and fluid-systems installers will find this union appropriate wherever a permanent or serviceable in-line tube connection is needed.

This compression union is suited for residential and light commercial fluid or refrigerant-line installations where two tube ends must be joined without flaring or soldering. The compression-by-compression end configuration makes it practical for retrofit or repair work, including tight-access installations where torch work is restricted or not permitted. Systems operating within the rated pressure and temperature envelope are the intended application.

Key Features

• Brass construction provides corrosion resistance suitable for water, refrigerant, and pneumatic service
• Compression x Compression end connections eliminate the need for soldering or flaring at both ends
• 13/16-18 thread size per SAE J-512 for dimensional interchangeability with mating hardware
• 150 psi maximum working pressure suits typical low-to-medium pressure plumbing and HVAC lines
• Wide service temperature range of -65 to 250 degrees F supports both refrigeration and hot-fluid applications

Compatibility

Designed as an OEM-style replacement or service fitting for compression tube union applications conforming to SAE J-512 with a 13/16-18 thread size.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians. Shut off and depressurize the line completely before disassembly or fitting installation. Hand-tighten the compression nut onto the fitting body, then tighten with a wrench per standard compression-fitting practice — do not overtighten, as brass compression fittings can deform the ferrule. Verify no leaks under system operating pressure before returning the system to service.
