Parker 12 Pntx-ss Stainless Steel Flared Tube Plug 3/4 in

Product Description

The PARKER 12 PNTX-SS is a stainless steel flared tube plug designed to terminate or cap off a 3/4-inch OD tube line using a 37-degree flare end connection. It is rated for up to 6000 psi maximum dynamic working pressure, making it suitable for high-pressure hydraulic and instrumentation applications. The all-stainless steel construction resists corrosion and handles the demands of industrial fluid systems. Plumbers, pipefitters, and fluid power technicians install this fitting when a tube run must be sealed off cleanly without modifying the flared tube end.

This plug is used in industrial, commercial, and OEM fluid system applications where 37-degree flare fittings are standard. Typical installation scenarios include capping unused ports on hydraulic manifolds, instrumentation tubing networks, and process fluid lines. It is suited for both new construction and service work where a reliable, leak-free tube termination is required in corrosive or high-pressure environments.

Key Features

• Stainless steel construction for corrosion resistance in harsh fluid system environments
• 37-degree flare end connection for secure, leak-free tube termination
• Rated to 6000 psi maximum dynamic working pressure
• Designed for 3/4-inch OD tube lines
• Compact profile fits tight installation spaces

Compatibility

Designed as an OEM-style replacement plug for fluid systems using 37-degree flare tube fittings with 3/4-inch outside diameter tubing.

Installation Notes

Installation is typically performed by a licensed pipefitter, plumber, or fluid power technician. Depressurize and drain the fluid system completely before removing or installing any tube fitting. Use the appropriate flare nut and tube preparation tools to ensure the mating flare surface is clean and undamaged before torquing. Follow applicable system design standards and facility safety procedures when working on pressurized fluid lines.
