Parker 12 Pnbz-ss Compression Tube Plug 3/4 in 5800 Psi

Product Description

The PARKER 12 PNBZ-SS is a stainless steel compression tube plug designed to seal the open end of a compression fitting or tubing line. It accepts tubing with a 3/4-inch outside diameter and holds a maximum working pressure of 5800 psi, making it suitable for demanding fluid and gas system applications. The compression-style end connection provides a positive, leak-resistant seal without welding or soldering. This plug is used by plumbers, pipefitters, and industrial maintenance technicians to terminate or cap off active or inactive lines during installation, maintenance, or system modification.

This plug is commonly used in hydraulic, pneumatic, instrumentation, and process piping systems where stainless steel construction is required for corrosion resistance or compatibility with aggressive media. Typical installations include industrial process lines, high-pressure fluid systems, and instrumentation tubing runs where a clean, reliable tube end termination is needed. It is sold in a package quantity of one.

Key Features

• Single-piece plug design terminates tubing lines cleanly and securely

Compatibility

Designed as an OEM-style compression fitting plug for use with 3/4-inch OD tubing in compression fitting systems requiring stainless steel construction.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified instrumentation technicians. Depressurize and isolate the line completely before installing or removing any compression fitting. Use a properly sized tubing cutter to ensure a clean, square tube end before seating the fitting. Follow applicable codes such as ASME B31.3 or system-specific pressure ratings when selecting and installing compression fittings.
