TUF-LUBE ™ Grooved Coupling Gasket Grease

Tuf-Lube is a mixed fatty acid soap dispersed in glycols and water solvents with a clay pigment filler. It resists evaporation and will not freeze. Mating of abutting pipes forces the gel into the cavity, thus providing the needed lubrication to complete coupling and seal the joint.

    The soap lubricant does not dry out when gaskets are stored in sealed plastic containers or bags.
