Parker 30KAIN13SPN Pneumatic Hose Coupler 3/8 in Brass

Product Description

The PARKER 30KAIN13SPN is a threaded pneumatic hose coupler designed for industrial compressed-air systems. Built to the Industrial Interchange standard, this coupler features a 3/8-inch body diameter and a 1/4-18 Female NPSF threaded connection for reliable, leak-resistant attachment to air lines and tools. Constructed from brass, it handles working pressures up to 300 psi and operates across a temperature range of -4 degrees F to 212 degrees F. It belongs to the Parker 30 Series and is sold individually. HVAC technicians, plumbers, and industrial maintenance personnel routinely use couplers of this type to connect pneumatic tools and equipment to shop-air or portable compressor systems.

This coupler is suited for light to moderate industrial pneumatic applications where an Industrial Interchange-style quick-connect fitting is required. The Female NPSF thread mates with standard male threaded nipples on air hoses, manifolds, or tool inlets. The brass construction makes it a practical choice in environments where corrosion resistance and moderate-pressure service are priorities. It is appropriate for use on portable compressors, stationary shop-air systems, and pneumatic tool lines in residential, commercial, and light industrial settings.

Key Features

• Industrial Interchange coupling standard for broad tool and hose compatibility
• Brass body construction for corrosion resistance and durability
• Maximum working pressure of 300 psi for compressed-air service
• Operating temperature range of -4 degrees F to 212 degrees F
• 1/4-18 Female NPSF threaded connection for secure, leak-resistant fit
• 3/8-inch body diameter for consistent airflow through the coupling

Compatibility

Designed as an OEM-style Industrial Interchange replacement coupler compatible with standard 1/4-18 Female NPSF threaded air hose assemblies and pneumatic tool connections in the Parker 30 Series.

Installation Notes

Installation is typically performed by qualified maintenance technicians or HVAC service professionals. Depressurize and bleed down the air system completely before removing or installing any pneumatic fitting. Apply an appropriate thread sealant to the Female NPSF threads in accordance with the fitting manufacturer guidance and local mechanical codes. Do not exceed the rated 300 psi working pressure or the 212 degrees F maximum temperature limit during service.
