Parker 3BLEN3-316 Compression Tube End Cap Ss

Product Description

The PARKER 3BLEN3-316 is a compression tube end cap manufactured from stainless steel for use in high-pressure fluid and gas line applications. It seals the open end of a compression tube fitting assembly, blocking flow at a termination point without requiring a threaded closure on the tube itself. Rated to 10,300 psi maximum working pressure and capable of handling temperatures from -425 degrees F to 1,200 degrees F, this end cap is engineered for demanding service conditions where corrosion resistance and pressure integrity are both critical. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers.

This end cap is suited for residential, commercial, and industrial piping systems that require a reliable compression-style tube termination. Typical applications include instrumentation lines, hydraulic circuits, pneumatic systems, and process piping where stainless steel fittings are specified for corrosion resistance or high-temperature exposure. Its NPT thread standard makes it compatible with standard North American pipe thread installations across a wide range of system configurations.

Key Features

• Maximum working pressure of 10,300 psi for high-pressure line applications
• Wide service temperature range: -425 degrees F to 1,200 degrees F
• Compression-style fitting for secure, leak-resistant tube termination without welding
• NPT thread standard for compatibility with standard North American pipe thread systems
• Single-piece package quantity for individual replacement or repair use

Compatibility

Designed as an OEM-style compression tube end cap for use in high-pressure instrumentation, hydraulic, and process piping systems requiring stainless steel NPT-thread fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with compression fitting assembly procedures. Depressurize and isolate the line completely before removing any existing fittings or installing this end cap. Do not over-tighten the compression nut, as excessive force can damage the ferrule and compromise the seal. Follow applicable codes including ASME B31.1 or B31.3 for pressure piping systems as required by your jurisdiction.
