Parker 25SFIN13SXZ High Flow Plug Coupling 1/4 Fnpt

Product Description

The PARKER 25SFIN13SXZ is a high flow pneumatic plug coupling designed for use in compressed air systems requiring fast, reliable connections. Built from steel, this threaded plug accepts a 1/4-inch FNPT connection and is rated for a maximum working pressure of 300 psi. The coupler body measures 23/32 inches in diameter with a hex size of 0.62 inches, making it compatible with standard hand and power tools for installation and removal. It handles operating temperatures from -4 degrees F to 212 degrees F, covering the full range of typical shop and industrial pneumatic service. Licensed HVAC technicians, plumbers, pipefitters, and mechanical contractors install this type of fitting as part of air supply, tool-drop, or process pneumatic circuits.

This plug coupling is suited for residential shop environments, light commercial facilities, and industrial compressed air distribution systems. It threads directly into female NPT ports on manifolds, tool inlets, or hose assemblies. The high flow design minimizes pressure drop across the connection, which is particularly important in systems running air tools, blow guns, or actuators that are sensitive to supply pressure loss. It ships individually and is sold as a single unit, making it a practical choice for single-point replacements or service calls where only one coupling needs to be swapped out.

Key Features

• High flow design reduces pressure drop for air tool and actuator applications
• 1/4-inch FNPT thread connects directly to standard female NPT ports
• Rated to 300 psi maximum working pressure
• Steel body provides durability in shop and industrial environments
• Operating range of -4 degrees F to 212 degrees F suits most compressed air service conditions
• 23/32-inch body diameter with 0.62-inch hex for wrench installation

Compatibility

Designed as an OEM-style replacement or service plug coupling for pneumatic compressed air systems using standard high flow interchange fittings with 1/4-inch FNPT threaded connections.

Installation Notes

Installation is performed by qualified pipefitters, HVAC technicians, or mechanical contractors working on compressed air systems. Depressurize and lock out the air supply before removing or installing any pneumatic coupling. Apply thread sealant appropriate for compressed air service to the FNPT threads before tightening with a wrench to the hex flats. Do not overtighten; inspect for leaks after restoring system pressure.
