Parker 30KAIN17SPN Pneumatic Hose Coupler 3/8 in 300 Psi

Product Description

The PARKER 30KAIN17SPN is a brass pneumatic hose coupler designed for compressed air and industrial fluid systems. It features a 3/8-18 female NPSF threaded connection and a 3/8-inch body diameter, making it a standard fit for Industrial Interchange pneumatic lines. The coupler is rated to 300 psi maximum working pressure and operates across a temperature range of -4 degrees F to 212 degrees F. At 0.264 pounds, it is a compact, single-piece fitting installed by HVAC technicians, pipefitters, and maintenance mechanics working on pneumatic tool lines, compressed air distribution, or industrial process systems.

This coupler is suited for residential and commercial pneumatic applications where Industrial Interchange compatibility is required. It threads directly onto female NPSF ports and is commonly installed at tool connections, manifold drops, and air compressor outlet lines. The brass construction makes it appropriate for dry air and many compatible compressed gas services. It is sold and packaged individually, making it a practical replacement or spare fitting for service vans and maintenance stock.

Key Features

• Female NPSF 3/8-18 threaded connection for secure, leak-resistant fitment
• Industrial Interchange series for broad pneumatic tool and equipment compatibility
• 300 psi maximum working pressure rated for demanding compressed air service
• Brass construction resists corrosion in typical pneumatic system environments
• Wide operating temperature range: -4 degrees F to 212 degrees F
• Compact overall length of 2.33 inches for tight installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for Industrial Interchange pneumatic systems using 3/8-18 female NPSF threaded connections.

Installation Notes

Install and service by qualified pipefitters or mechanics familiar with compressed air systems. Shut off and bleed down all system pressure before removing or installing any coupler. Apply appropriate thread sealant compatible with the service medium and follow applicable codes such as ASME B31.1 for pressure piping. Do not exceed the rated 300 psi working pressure or the maximum temperature of 212 degrees F.
