Company officials say their Klo-Shure insulation coupling reduces the time needed to install closed-cell, elastomeric insulation on copper tubing by up to 60%. It creates a 360-degree vapor barrier, and improves finished appearance by eliminating unsightly insulation bulges. The coupling is high-strength, using an internal design that supports and secures copper tubing and tubing insulation at clevis hangers and strut-mounted clamps. Couplings to support 1/4- to 2 1/8-in. diameter tubing and support 3/8- to one-in.-thick tubing insulation are available.
