Midland Industries 595320C Dot Push-to-connect Plug 5/32 in

Product Description

The MIDLAND INDUSTRIES 595320C is a D.O.T.-rated push-to-connect plug designed to seal off open ports in compressed air and pneumatic brake line systems. Constructed with a plastic composite body, this plug accepts a 5/32-inch plug-in stem connection and provides a secure, tool-free closure. It is commonly installed by fleet maintenance technicians and commercial vehicle service professionals working on DOT-compliant air brake circuits. The lightweight design keeps the part easy to handle during service, and the push-to-connect mechanism allows fast port sealing without additional fittings or threading tools.

This plug is suited for use in D.O.T. composite body push-to-connect pneumatic systems, typically found in commercial trucking, trailer air brake assemblies, and related compressed air plumbing. Its compact profile makes it a practical choice for plugging unused or capped ports during system modifications, repairs, or pressure testing. The 5/32-inch stem size targets smaller-diameter port applications common in instrument air lines and control circuits.

Compatibility

Designed as an OEM-style replacement plug for D.O.T. composite body push-to-connect pneumatic systems requiring a 5/32-inch plug-in stem port closure.

Installation Notes

Installation is performed by qualified fleet or pneumatic system technicians. Before servicing any air brake or compressed air circuit, depressurize the system completely and verify zero pressure with a gauge before handling fittings. Push-to-connect plugs should be inserted straight and fully seated until the retention mechanism engages. Follow all applicable DOT and SAE regulations governing air brake system repairs on commercial vehicles.
