The Draper D572 Brake and Air Line Seal cures due to the absence of air between close fitting metal surfaces. Prevents loosening and leakage from shock and vibration. Good chemical/solvent resistance to ethanol, motor oil, unleaded petrol and brake fluid.

The Draper D542 for metal threaded fittings especially useful on hydraulic pipes. Used on low, medium and high-pressure lines and cures to form a tough high-pressure seal.
