Red Emergency Gladhand Seal for Semi Trucks & Trailers

Gladhand couplers connect the tractor's air brake lines to the trailer. The red gladhand identifies the trailer emergency or supply air line connection, while the blue gladhand identifies the service or control line connection.

Gladhand seals help maintain the connection between the mating couplers and reduce compressed air leakage during operation.

The Power Products emergency seal is intended for compatible red gladhand fittings used on:

• Heavy-duty semi trucks
• Commercial truck tractors
• Dry van trailers
• Refrigerated trailers
• Flatbed trailers
• Commercial freight trailers
• Vocational trucks and trailers
• Other compatible tractor-trailer air brake connections

Polyurethane vs. Rubber Gladhand Seals

Polyurethane gladhand seals provide a durable alternative to conventional rubber gaskets for compatible commercial vehicle applications.

The resilient polyurethane material is designed to handle regular coupling and uncoupling while maintaining a sealing surface against the mating gladhand.

Replace seals showing cracks, cuts, deformation, excessive wear, or leakage. Always use the correct seal design for the installed gladhand coupling.

Helps Maintain Tractor-Trailer Air Brake Connections

A damaged gladhand seal can allow compressed air to leak from the tractor-to-trailer connection. Maintaining these seals helps support proper air system operation and prevent connection-related air loss.

Common signs that a gladhand seal needs replacement include:

• Audible air leakage at the gladhand connection
• Cracked, split, or hardened sealing material
• Flattened or deformed sealing lips
• Loose or improperly seated seals
• Visible wear from repeated coupling
• Missing or damaged gladhand gaskets

Air leaks should be diagnosed and repaired before operating the vehicle.

Gladhand Seal Installation & Maintenance

Before replacing a gladhand seal, safely park and secure the vehicle and follow the manufacturer's air brake system maintenance procedures.

Inspect the gladhand coupling for damage, corrosion, contamination, or worn mating surfaces. Remove the damaged seal and install the correctly sized replacement according to the coupling manufacturer's instructions.

Verify that the seal is properly seated and check the reconnected air system for leakage before returning the vehicle to service.

Important: Use this red seal for the applicable emergency/supply gladhand connection. Confirm the correct seal profile and dimensions before installation. Commercial vehicle air brake systems are safety-critical and should be maintained by qualified personnel.
