Parker 25KAAN17MPN Pneumatic Hose Coupling 1/4 in High Flow

Product Description

The PARKER 25KAAN17MPN is a brass pneumatic hose coupler designed for compressed air and pneumatic tool applications. It features a 3/8-18 MNPT threaded connection and a 1/4-inch body diameter, matching the High Flow interchange standard for broad tool compatibility. Built from brass, this coupler handles working pressures up to 300 psi and temperatures from -4 degrees F to 212 degrees F. It belongs to the Parker 25 Series and is intended for use by HVAC technicians, industrial maintenance crews, and pneumatic system installers who require a reliable, high-flow coupler in demanding service environments.

This coupler is suited for residential and light commercial pneumatic systems, compressed air distribution lines, and pneumatic tool hookups where a High Flow interchange coupler is specified. The 3/8-18 MNPT thread makes it compatible with standard NPT-threaded ports on air hoses, manifolds, and pneumatic equipment. It is a single-piece replacement component sold individually and fits into systems requiring the 25 Series High Flow coupler standard.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic system service. Depressurize and bleed the air line completely before disconnecting or installing any coupler. Apply thread sealant appropriate for pneumatic service to the MNPT threads before making connections. Follow applicable OSHA and local compressed air safety guidelines during installation and pressure testing.
