Midland Industries 28512 Auto Interchange Male Plug 3/8 in

Product Description

The MIDLAND INDUSTRIES 28512 is a steel automotive interchange male plug designed for pneumatic quick-connect applications. It features a 3/8-inch body with a male automotive interchange profile on one end and a 1/4-inch male NPT thread on the other, allowing direct connection between air lines and pneumatic tools or fittings. Rated to 300 psi maximum operating pressure, this plug is built for reliable service in shop air systems and mobile equipment pneumatic circuits. Licensed tradespeople and service technicians install this type of fitting when connecting air hoses to manifolds, valves, or tool inlets that require an NPT-threaded entry point.

This plug is suited for use in residential, commercial, and industrial pneumatic systems where Parker or automotive interchange-style quick-connect couplers are in service. It fits into shop compressor setups, service truck air systems, and equipment requiring a standard automotive interchange interface. The 3/8-inch body size is a common specification in light-duty and medium-duty air tool applications across automotive service, general manufacturing, and HVAC service environments.

Key Features

• Male automotive interchange profile mates with standard Parker and Tru-Flate compatible couplers
• 1/4-inch male NPT thread for direct installation into NPT-tapped ports or fittings
• 300 psi maximum operating pressure rating
• 3/8-inch body size fits common automotive interchange quick-connect systems
• Steel construction for durability in shop and mobile service environments

Compatibility

Compatible with Tru-Flate connectors and Parker automotive interchange-style couplers. Designed for pneumatic systems using the standard automotive interchange quick-connect profile with 1/4-inch NPT-threaded ports.

Installation Notes

Depressurize and bleed down the air system completely before removing or installing any pneumatic fittings. Apply thread sealant tape to the male NPT threads per standard practice before threading into the receiving port. Hand-tighten first, then wrench-tighten to avoid cross-threading steel NPT connections. Installation should follow applicable OSHA and local compressed air safety guidelines.
