Klo-Shure Co. has introduced Insulation Couplings that are designed to support copper tubing while securing elastomeric insulation. They are molded from high strength DuPont plastic, and have a patented design to support 1/4" to 2 1/8" diameter copper tube and secure 3/8" to 1" thick tubing insulation. Two versions are available. The basic version can be used to connect two lengths of insulation, or to act as a support in a suspension system. The other version is for use in strut systems. Installation involves slipping the Coupling around copper tubing, inserting the mating sections of tubing insulation into the coupling and securing the device with a provided metal clip. Klo-Shure Co.
