Parker 30KAAN21SPN Pneumatic Hose Coupler 3/8 in Brass Nptf

Product Description

The PARKER 30KAAN21SPN is a brass pneumatic hose coupler in the Parker 30 Series, designed for industrial interchange pneumatic systems. It features a 3/8 inch body diameter and a 1/2-14 male NPTF threaded connection, making it a reliable choice for connecting air lines and pneumatic tools in demanding shop and industrial environments. Rated to 300 psi maximum working pressure, this coupler handles the pressure ranges common to industrial compressed air systems. The brass construction offers good corrosion resistance and durability for general-purpose pneumatic service. Licensed HVAC techs, pipefitters, and industrial maintenance professionals install this type of fitting as part of compressed air distribution and pneumatic tool hookups.

This coupler is suited for industrial interchange pneumatic applications where a 3/8 inch body, male NPTF threaded coupler is required. The industrial interchange configuration is one of the most widely used coupler standards in North American shops and production facilities, compatible with industrial interchange nipples and plugs across most tool brands. It is appropriate for both light manufacturing and heavy-duty maintenance environments where reliable, leak-free connections are critical. The operating temperature range of -4 degrees F to 212 degrees F makes it suitable for a broad range of indoor and outdoor compressed air applications.

Installation Notes

Installation should be performed by a qualified pipefitter or industrial maintenance technician familiar with compressed air systems. Depressurize and lock out the air supply before removing or installing any pneumatic fitting. Apply thread sealant appropriate for NPTF connections per the fitting manufacturer's guidance, and confirm all connections are leak-free before returning the system to service. Follow applicable facility safety codes and OSHA compressed air guidelines during installation.
