Description
25-pack of universal black polyurethane gladhand seals for tractor-trailer air brake couplers. The polyurethane compound resists drying, tearing, and brake-line oil better than rubber, sealing the service and emergency air glands between tractor and trailer to prevent supply leaks at the coupling face.
