Murphy's 1950, 1 Gal Concentrated Extra Slippery Tire And Tube Mounting Compound is a blend of natural polymers, surfactants, corrosion inhibitors, and stabilizers. It does not soften or swell most rubber formulations. Murphy's 1950 can be used in any application where the rubber needs to be lubricated relative to its dry state. It provides low friction to prevent twisting and cracking; therefore, parts will not grab or seize the metal and seat readily and smoothly. Murphy's Concentrated Extra Slippery Tire And Tube Mounting Compound have been used in the tire industry for many years to assure seals with minimum distortion. It dries to a low slip residue that helps prevent slippage under high loads and high torque.
