Parker 6ECR6-316 Compression Tube Union Stainless Steel

Product Description

The PARKER 6ECR6-316 is a stainless steel compression tube union designed for high-pressure fluid and gas line connections in demanding industrial and mechanical systems. This fitting uses all-compression end connections, eliminating the need for soldering, welding, or threaded preparation on the tube ends. It is rated for a maximum working pressure of 6600 psi and handles a wide temperature range from -425 degrees F to 1200 degrees F, making it suitable for cryogenic through high-heat service environments. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting in instrumentation, process piping, and specialty fluid systems.

This compression union is appropriate for residential and commercial applications where stainless steel corrosion resistance and pressure integrity are required. Typical install scenarios include instrument tubing runs, hydraulic lines, refrigeration-adjacent systems, and chemical process piping where tube-to-tube union connections must be made without heat or threading. The all-compression design speeds up installation and allows the connection to be disassembled and remade when service access is needed.

Key Features

• All-compression end connections on both sides — no soldering or welding required
• 316 stainless steel construction for corrosion resistance in harsh or wet environments
• Maximum working pressure of 6600 psi for high-pressure service
• Wide temperature range: -425 degrees F to 1200 degrees F, covering cryogenic through high-heat applications
• Union configuration allows in-line tube-to-tube joining with the ability to disconnect for service

Compatibility

Designed as an OEM-style replacement or direct-use compression union fitting for stainless steel tubing systems operating within rated pressure and temperature limits.

Installation Notes

Installation is typically performed by licensed pipefitters or plumbers working on instrumentation or process piping systems. Depressurize and isolate the line completely before removing or installing any compression fitting. Use appropriate tube cutters and deburring tools to ensure a clean, square tube end before seating the ferrule. Follow applicable codes such as ASME B31.1 or B31.3 for process piping when selecting and installing high-pressure compression fittings.
