K-Packers are designed to provide a sand tight seal between the well screen and casing and are typically used on the top of telescope size screens in the water well, construction and environmental drilling industries.
K-Packers eliminate contamination of underground water sources from intrusion of surface pollutants by effectively sealing the casing to the bore hole.
They also eliminate cross contamination of underground water source by sealing out zones of mud, high mineral content water, or other pollutants.
