Parker 23KAAN13MPN Pneumatic Coupler 1/4 in Brass 300 Psi

Product Description

The PARKER 23KAAN13MPN is a brass pneumatic hose coupler designed for compressed-air and pneumatic tool lines in industrial environments. Part of the Parker 23 Series, it features a male NPTF threaded connection at 1/4-18 and a 1/4 inch body diameter. The coupler is rated to 300 psi maximum working pressure and handles temperatures from -4 degrees F to 212 degrees F, making it suitable for a wide range of shop-floor and field pneumatic service conditions. HVAC technicians, plumbers, and industrial maintenance trades install this type of fitting to connect pneumatic hoses and tools to air supply lines with a reliable, leak-resistant threaded interface.

This coupler suits residential and commercial pneumatic systems where Industrial Interchange-style quick-connect components are standard. The 1/4-18 male NPTF thread seals on the threads themselves, reducing the need for additional thread sealant in many applications. Typical install scenarios include air compressor outlet manifolds, pneumatic tool drop lines, and general-purpose shop-air distribution headers. The 0.81 inch hex size accommodates standard open-end or combination wrenches for installation and removal.

Key Features

• 300 psi maximum working pressure rated for demanding pneumatic service
• Brass construction resists corrosion in compressed-air environments
• Operating range of -4 degrees F to 212 degrees F covers most shop and field conditions
• Compact 2.34 inch overall length for use in tight installation spaces

Compatibility

Designed as an OEM-style replacement or direct-install coupler for pneumatic systems using Industrial Interchange style quick-connect fittings with 1/4-18 male NPTF threaded connections.

Installation Notes

A licensed or qualified trades professional should depressurize and lock out the air supply before removing or installing any pneumatic fitting. Use a proper-sized open-end or combination wrench on the 0.81 inch hex to avoid rounding the fitting body. NPTF threads are designed to seal on the thread form, but inspect threads for damage before installation and apply thread sealant per shop or job-site standards if required. Do not overtighten, as brass fittings can crack under excessive torque.
