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.
