Using the correct lube when installing a shaft seal can mean all the difference. Since a lubricant of some form is almost always required to properly seat a shaft seal and during the installation chances lubricant will come in contact with sealing faces. Once a PTFE or silicone based product touches the seal faces, it is nearly impossible to remove. Once the pump is started, the PTFE or silicone draws the carbon from the primary ring, and smears this material on the face of the mating ring, causing a build-up which eventually destroys the seal.
U.S Sealube is a waterbased formula specifically designed to lubricate rubber, making the installation of mechanical seals fast and easy. Being waterbased evaporation takes place leaving the seal dry to the touch. The lubricity is gone and will not return, even in the presence of moisture. Your seal is now locked in place.
