Parker 62C-4 Compression Tube Union 1/4 in Od Brass

Product Description

The PARKER 62C-4 is a brass compression tube union designed to join two lengths of 1/4-inch OD tubing in a straight-line, inline configuration. It uses compression-style end connections on both sides, eliminating the need for flared ends or soldering during assembly. Rated to 300 psi maximum working pressure and suitable for temperatures ranging from -65 degrees F to 250 degrees F, this fitting is built for reliable service in refrigeration, hydraulic, and pneumatic tubing runs. It conforms to SAE J-512 standards, making it a recognized option for trade professionals who need a verified, spec-compliant union fitting.

This fitting is used in residential and light commercial applications where 1/4-inch OD tubing must be joined or extended. Common install scenarios include refrigeration line repairs, instrument tubing connections, and low-pressure hydraulic or pneumatic circuits. The compression-by-compression configuration suits field repairs where disassembly and reassembly may be required. Licensed HVAC technicians, plumbers, and refrigeration mechanics are the primary installers of this fitting type.

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 1/4-inch OD compression tubing, conforming to SAE J-512 specifications.

Installation Notes

Installation is performed by licensed HVAC technicians, refrigeration mechanics, or plumbers depending on the application. Always depressurize and isolate the tubing circuit before disassembling or installing compression fittings. Use the appropriate tubing cutter to ensure a clean, square tube end before seating the compression nut and ferrule. Do not overtighten compression nuts, as this can deform the ferrule and cause leaks.
