Polywater® GrandSlam™ Pipe Joint Lubricant

Polywater® GrandSlam™ Pipe Joint Lubricant

Minimizes Broken Bells in Concrete Pipe Joining

Pipe manufacturers and contractors know too well the reason for damaged and “blown” bells in concrete and gasketed PVC pipe joining. Improperly lubricated gaskets too often loop out from their grooves during pipe joining (“fish mouthing”) and cause bells to split. Field people want to properly lubricate pipe joints and gaskets; but with smelly lubricants that drip, melt, freeze, and wash off in water, sometimes it’s impossible to do the job properly.

Polywater® GrandSlam™ Pipe Joint Lubricant for concrete, ductile iron, PVC pipe, and boxes eliminates the problems with other pipe joint lubricants. It is an odor-free, easy-to-apply, soft paste material. GrandSlam™ Pipe Joint Lubricant is subaqueous and clings to both wet and dry surfaces on concrete, ductile iron, and plastic pipes. It doesn’t wash off, even with flowing water. GrandSlam™ Pipe Joint Lubricant is compatible with rubber gasket materials. It provides maximum lubricity of the rubber gasket against the concrete bell for damage-free pipe joints.

GrandSlam™ Pipe Joint Lubricant comes in two grades: Regular Grade GSQ and Winter Grade GWQ (for cold weather use in temperatures as low as -0°F/-18°C).
