A Service Brake Tube Assembly carries high-pressure brake fluid from the brake slack adjuster to the wheel brakes. It consists of a rigid metal tube with an ORFS (O-Ring Face Seal) sleeve and an ORFS nut at each end. The ORFS sleeve is permanently attached to the tube, providing a secure connection point for the hydraulic fittings. The ORFS nut is threaded onto the sleeve, allowing for easy connection and disconnection of the brake line.Attributes:• Withstands 19750 kPa of Relief Valve Pressure• Manufactured to precise specifications and is built for durability and reliabilityApplications:A Service Brake Tube Assembly acts as a secured pathway to conduct the hydraulic brake fluid from the brake adjuster to the rear axle without any leaks for secure braking.
