Parker 6BLEN6-316 Compression Tube End Cap 3/8 Ss

Product Description

The PARKER 6BLEN6-316 is a stainless steel compression tube end cap designed to terminate a 3/8-inch OD tube line in high-pressure fluid or gas systems. The fitting accepts a 3/8-inch NPT thread and seals via compression, eliminating the need for welding or brazing at the termination point. Rated to 6600 psi maximum working pressure, this end cap handles demanding service conditions, including cryogenic environments down to -425 degrees F and high-temperature applications up to 1200 degrees F. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting in instrumentation, process, and utility systems.

This end cap is suited for residential and commercial applications where a compression tube run must be capped off cleanly and securely. Typical use cases include shutting off a branch line during system modifications, blanking an unused port on a manifold, or protecting an open tube end during staged construction. The stainless steel 316-grade construction makes it appropriate for corrosive media, marine environments, and sanitary process lines where carbon steel or brass fittings are not acceptable.

Key Features

• Stainless steel construction resists corrosion in aggressive media and outdoor environments
• 6600 psi maximum working pressure rated for high-pressure instrumentation and process lines
• Compression end connection eliminates soldering or brazing at the cap point
• 3/8-inch NPT thread standard for compatibility with standard pipe fittings and manifolds
• Extreme temperature range from -425 degrees F to 1200 degrees F suits cryogenic and high-heat service
• Compact 1.01-inch overall length minimizes protrusion in tight installations

Compatibility

Designed as an OEM-style compression tube end cap for 3/8-inch OD tubing with 3/8-18 NPT thread, suitable for use in standard instrumentation and process piping systems that accept compression-style fittings.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable IPC and system-specific pressure codes. Depressurize and isolate the line completely before removing or installing any compression fitting. Do not over-tighten the compression nut, as stainless ferrules can gall; follow the fitting manufacturer's standard turn-past-finger-tight procedure. Confirm all connections are leak-tested at working pressure before returning the system to service.
