Parker 62HD-2 Brass Compression Tube Union 4300 Psi

Product Description

The PARKER 62HD-2 is a brass compression tube union designed to join two compression-end tube lines in a single, inline fitting. It creates a secure, leak-resistant connection without soldering or brazing, making it a practical choice for high-pressure fluid and gas line work. Constructed from brass, the 62HD-2 is rated to 4300 psi working pressure, placing it in the heavy-duty class suitable for demanding hydraulic, pneumatic, and instrumentation service. Licensed plumbers, HVAC technicians, and instrumentation mechanics install this fitting where a removable, reusable tube connection is required.

This union fitting is used in residential and commercial applications wherever two compression-end tubes must be joined end-to-end. Common install scenarios include refrigeration and instrumentation tubing runs, compressed air distribution lines, and hydraulic control circuits. The compression-by-compression configuration allows the technician to make field connections without specialty tooling beyond standard wrenches, and the union design allows the line to be broken and re-made during service or future modifications.

Key Features

• Brass construction provides corrosion resistance and compatibility with a broad range of fluids and gases
• 4300 psi maximum working pressure rated for heavy-duty service
• Compression x compression end connections on both sides eliminate the need for soldering or brazing
• Union design allows the connection to be broken and re-made without cutting tubing
• Compact inline form factor suits tight plumbing and instrumentation installations

Compatibility

Designed as an OEM-style inline union for compression-end tubing in hydraulic, pneumatic, instrumentation, and plumbing systems where the tube outside diameter matches the fitting series.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or instrumentation mechanics following applicable codes such as IPC or ASME B31 piping standards. Depressurize and isolate the line completely before disassembly or installation. Use two wrenches when tightening compression fittings to prevent tube rotation and avoid over-tightening, which can deform the ferrule and compromise the seal. Confirm tube end is cut cleanly and squarely and deburred before inserting into the fitting body.
