Parker 30KAAN13SPN Pneumatic Coupler 3/8 in Brass 300 Psi

Product Description

The PARKER 30KAAN13SPN is a brass pneumatic hose coupler designed for compressed air and industrial fluid systems. Part of Parker's 30 Series, it features a 3/8 inch body diameter and a 1/4-18 male NPTF threaded connection. It is rated for a maximum working pressure of 300 psi and handles temperatures from -4 degrees F to 212 degrees F. The coupler mates with Industrial Interchange-style pneumatic fittings and plugs, making it a widely compatible choice for shop air lines, pneumatic tooling circuits, and general-purpose compressed air distribution. Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians working on compressed air systems.

This coupler is suited for both light industrial and commercial compressed air applications. It is commonly installed on air compressor outlets, pneumatic tool connections, hose assemblies, and manifold drop lines. The brass body construction provides corrosion resistance appropriate for dry or lightly lubricated compressed air service. The male NPTF thread form creates a pressure-tight seal on contact, reducing reliance on thread sealant alone. The Industrial Interchange configuration ensures broad compatibility with standard pneumatic quick-disconnect systems found across manufacturing, automotive, and maintenance environments.

Key Features

• 300 psi maximum working pressure for demanding compressed air service
• 1/4-18 male NPTF threaded connection for pressure-tight engagement
• 3/8 inch body diameter in Parker 30 Series Industrial Interchange configuration
• Brass construction for corrosion resistance in compressed air and light fluid service
• Rated from -4 degrees F to 212 degrees F for broad temperature range coverage
• Overall length of 2.49 inches with 0.94 inch hex for standard wrench installation

Compatibility

Designed for use with Industrial Interchange-style pneumatic quick-disconnect systems. Compatible with Parker 30 Series plugs and other Industrial Interchange-standard components sharing a 3/8 inch coupler size and 1/4-18 NPTF thread entry.

Installation Notes

Shut off and bleed all compressed air pressure from the line before installing or replacing any pneumatic coupler. Use an appropriately sized open-end or adjustable wrench on the 0.94 inch hex — do not grip the body. Apply PTFE thread tape or an appropriate thread sealant to male NPTF threads per system requirements and local codes. Verify working pressure of the installed system does not exceed the 300 psi rating of this coupler.
