Parker 8ECR8-316 Compression Tube Union Stainless Steel

Product Description

The PARKER 8ECR8-316 is a stainless steel compression tube union designed for high-pressure, wide-temperature-range fluid and gas line connections. Built from 316 stainless steel with all-compression end connections, this union provides a reliable, leak-resistant joint without welding or threading. It is rated for a maximum working pressure of 6300 psi and handles temperatures from -425 degrees F to 1200 degrees F, making it suitable for demanding industrial, chemical, and instrumentation applications. Licensed plumbers, pipefitters, and instrumentation technicians are the primary installers of this fitting type.

This compression tube union is suited for use in high-pressure process lines, instrumentation tubing systems, hydraulic circuits, and industrial fluid handling systems where stainless steel construction and broad temperature tolerance are required. The all-compression design makes it appropriate for applications where permanent connections are not practical or where tube lines require periodic disassembly and reassembly. It is commonly found in commercial and industrial settings rather than standard residential plumbing installations.

Key Features

• 316 stainless steel construction resists corrosion in aggressive media and wet environments
• All-compression end connections eliminate the need for welding or threaded joints
• Maximum working pressure of 6300 psi supports high-pressure process and instrumentation lines
• Temperature range of -425 degrees F to 1200 degrees F covers cryogenic through high-heat service
• Union configuration allows tube lines to be disconnected and reconnected without cutting tubing

Compatibility

Designed as an OEM-style compression tube union fitting for use in industrial instrumentation and high-pressure fluid handling systems that require all-compression stainless steel connections.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified instrumentation technician familiar with compression fitting procedures. Shut off and depressurize the line completely before disassembly or installation. Ensure tubing is cut cleanly and squarely and is free of burrs before inserting into the compression fitting. Follow applicable codes including ASME and local piping standards when working in pressurized systems.
