It connects the trailer’s gladhand to the tractor’s air supply, delivering air to release the spring brakes. Replace it when the nylon tubing shows cracks, abrasion, or leaks, when the brass ends or swivel fittings are damaged, or if the hose no longer holds pressure. The heavy-duty design with plated steel spring guards and thread sealant helps prevent kinking and ensures a secure, long-lasting connection.
