Midland Industries 39516 Emergency Swing Away Gladhand

Product Description

The MIDLAND INDUSTRIES 39516 is an emergency swing-away gladhand designed for use in air brake systems on commercial vehicles and trailers. The aluminum body keeps weight low while providing solid resistance to corrosion in road and weather conditions. A rubber seal ensures an airtight connection at the coupling face, and the 1/2 inch male pipe thread (MPT) inlet connects directly to the vehicle or trailer air line. The swing-away design allows the gladhand to pivot clear of the coupling position, protecting the seal and body from damage during coupling and uncoupling operations. This fitting is identified by its red body color and black seal, marking it as an emergency-circuit gladhand per standard air brake color coding.

This gladhand is used in the emergency air circuit of air brake systems on semi-trailers, flatbeds, and other commercial vehicle configurations that require DOT-compliant brake system connections. The emergency circuit maintains brake release pressure while the vehicle is in motion; a loss of pressure in this circuit causes the brakes to apply automatically. The swing-away bracket mount style suits applications where connection protection and ease of hookup are priorities in high-cycle fleet or over-the-road service environments.

Key Features

• Swing-away design pivots the gladhand body out of the coupling path to reduce wear and seal damage
• Aluminum body construction reduces overall fitting weight while resisting corrosion
• Rubber seal provides a reliable airtight face seal at the gladhand coupling interface
• 1/2 inch MPT inlet threads directly onto standard air line fittings and valve ports
• Red body color identifies the emergency air circuit per standard air brake color coding conventions
• Bracket mount configuration for fixed installation on trailer or vehicle frame

Compatibility

Designed as an OEM-style replacement or service fitting for emergency air brake circuit gladhand connections on commercial vehicles and trailers equipped with 1/2 inch MPT air line ports.

Installation Notes

Installation should be performed by a qualified commercial vehicle technician familiar with air brake system regulations and DOT requirements. Depressurize the air system completely before removing or installing any air brake fitting. Apply appropriate thread sealant to the MPT threads and torque to fitting manufacturer standards using a properly sized wrench. Verify the circuit is leak-free and the gladhand couples and releases correctly before returning the vehicle to service.
