Parker 23KAIN13MPN Pneumatic Hose Coupling 1/4 Inch Brass

Product Description

The PARKER 23KAIN13MPN is a brass pneumatic hose coupler designed for industrial compressed-air systems. Part of the 23 Series, this coupler features a 1/4-18 female NPSF threaded connection and a 1/4 inch body diameter. It is rated for a maximum working pressure of 300 psi and handles temperatures from -4 degrees F to 212 degrees F. The all-brass construction provides corrosion resistance suitable for demanding shop-floor and industrial service environments. Installation requires no special tools beyond standard wrenches sized for its 0.81 inch hex. HVAC technicians, pipefitters, and industrial maintenance mechanics are the typical installers.

This coupler is suited for residential and commercial compressed-air distribution lines, pneumatic tool connections, and industrial automation plumbing where an Industrial Interchange-style quick-connect fitting is required. The female NPSF thread is a common interface on air compressor outlets, manifolds, and pneumatic control lines. At 2.19 inches overall length and 0.20 pounds, it is compact enough for tight service spaces. It follows the Industrial Interchange standard, making it widely compatible across pneumatic tool and fitting systems that share that interchange profile.

Key Features

• Industrial Interchange coupler standard for broad pneumatic tool compatibility
• Brass construction resists corrosion in compressed-air and light fluid service
• 300 psi maximum working pressure rating
• Operating temperature range: -4 degrees F to 212 degrees F
• 1/4-18 female NPSF threaded connection for secure, leak-resistant fit
• Compact 2.19 inch overall length suits confined plumbing spaces

Compatibility

Designed as an OEM-style replacement coupler for Industrial Interchange pneumatic systems using 1/4 inch body, 1/4-18 female NPSF threaded fittings.

Installation Notes

Installation should be performed by a qualified pipefitter or pneumatic systems technician. Depressurize and isolate the air line fully before removing or installing any coupler. Apply thread sealant appropriate for pneumatic service to the NPSF threads per the fitting manufacturer guidance. Do not overtighten; use the hex flats and a properly sized wrench to achieve a snug, leak-free connection without distorting the brass body.
