Parker 62CA-4-3 Brass Compression Tube Union

Product Description

The PARKER 62CA-4-3 is a brass compression tube union designed to join two compression-end tubing runs in a single inline fitting. It accepts compression connections on both ends, creating a secure, leak-resistant joint without soldering or welding. Rated to 1900 psi maximum working pressure, it handles demanding fluid and pneumatic service across a wide temperature range of -65 degrees F to 250 degrees F. Plumbers, pipefitters, and fluid-system technicians install this fitting in hydraulic, pneumatic, and fluid-distribution lines where a reliable tube-to-tube union is required.

The 62CA-4-3 is suited for use in residential and commercial plumbing, HVAC refrigerant-adjacent fluid lines, pneumatic control circuits, and hydraulic distribution systems. Its brass construction makes it compatible with water, air, and a broad range of compatible media. The compression x compression end configuration allows field installation without specialty tooling, making it a practical choice for service and retrofit work where tubing must be joined or rejoined in tight spaces.

Key Features

• Compression x compression end connections on both ends for tool-free, solder-free assembly
• 1900 psi maximum working pressure for high-demand fluid and pneumatic service
• Wide operating temperature range: -65 degrees F to 250 degrees F
• Brass construction for corrosion resistance and durability in wet and pneumatic environments
• Union configuration allows tubing sections to be separated and rejoined without cutting
• NPTF thread standard where applicable for pressure-tight connections

Compatibility

Designed as an OEM-style replacement or direct-install compression tube union for fluid, pneumatic, and plumbing systems requiring a compression x compression inline union fitting.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or qualified fluid-system technicians. Shut off system pressure and depressurize all lines before disassembly or installation. Ensure tubing ends are cut square and deburred before seating into the compression fitting to achieve a leak-free joint. Verify that tubing material and outside diameter are compatible with the fitting before final assembly.
