Parker 8SC8-316 Compression Tube Union 6300 Psi Ss

Product Description

The PARKER 8SC8-316 is a stainless steel compression tube union designed to join two compression-end tube lines in a single inline fitting. It accepts compression connections on both ends, making it suitable for high-pressure instrumentation, fluid transfer, and process piping applications. Rated to 6300 psi maximum working pressure, this union is built for demanding service environments where leakfree, vibration-resistant connections are required. Licensed plumbers, pipefitters, and instrumentation technicians typically specify this fitting where stainless steel corrosion resistance and high-pressure integrity are essential.

This compression union fits into residential and commercial plumbing, industrial process lines, pneumatic systems, and hydraulic instrumentation tubing runs. Its compression-by-compression end configuration allows connection without welding or threading, making it well suited for field installation in confined spaces or where flame-free work is required. The stainless steel construction handles aggressive media and elevated pressures that would degrade brass or carbon steel alternatives.

Key Features

• 6300 psi maximum working pressure for high-pressure process and instrumentation service
• Compression x compression end connections on both ends — no threading or welding required
• 316 stainless steel construction for corrosion resistance in harsh or wet environments
• Inline union design for straight tube-to-tube joining
• NPT thread standard reference for system compatibility
• Compact, lightweight profile at 0.21 pounds

Compatibility

Designed as an OEM-style compression fitting for use in high-pressure tubing systems requiring stainless steel construction and compression-style end connections on both ports.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or instrumentation technicians. Before installation, depressurize and isolate the tubing line completely and verify tube OD is clean, cut square, and free of burrs. Follow the fitting manufacturer torque sequence and ferrule seating procedure — hand-tighten then advance with a wrench per standard compression fitting practice. Confirm all connections are leak-tested at system operating pressure before returning the line to service.
