Parker 25C Pneumatic Hose Coupler 0.375 in Female Nptf

Product Description

The PARKER 25C is a female NPTF industrial pneumatic hose coupler designed for use in compressed-air distribution and pneumatic tool applications. Built from steel with a zinc chromate finish, this coupler features a 0.375-inch body diameter and a 1/4-18 NPTF threaded connection. The threaded interface provides a pressure-tight seal without the need for additional sealant on most applications. It is a standard industrial-interchange-style coupler installed by HVAC technicians, plumbers, pipefitters, and general maintenance professionals working with pneumatic systems.

This coupler suits residential, commercial, and light industrial compressed-air setups where a reliable female quick-connect fitting is required at an air hose, manifold, or tool drop point. The 1/4-18 NPTF female thread matches common male nipples and plugs used in standard industrial interchange pneumatic systems. The compact body diameter keeps installation straightforward in tight panel or manifold configurations.

Compatibility

Designed as an OEM-style replacement or service fitting for industrial pneumatic systems using standard 3/8-inch body industrial interchange couplers with 1/4-18 NPTF female threaded inlets.

Installation Notes

Depressurize and bleed the air line completely before removing or installing any pneumatic fitting. NPTF threads are self-sealing by design, but inspecting threads for damage before installation is standard practice. Use an appropriate wrench on the hex body to avoid deforming the coupler body. Follow applicable shop-air and pneumatic system codes for your jurisdiction when integrating into a compressed-air distribution system.
