Fitting clamps in three styles — ear, worm gear, and double bond — attach tubing and hoses to other components. The Oetiker ear clamp comes in stainless steel and zinc-plated carbon steel. They adapt to expansion and contraction, yet remain secure and tamperproof. Sizes range from 5/32 to 19/16-in. nominal OD. Worm-gear clamps tighten with a screwdriver. Stainless-steel construction provides durability, and a lined version is available for use with soft tubing such as silicone. Worm-gear clamps come in a wide range of sizes — from 3/8 through 6 in., nominal diameter. Double-bond clamps are made from UL-listed, black nylon 6-6 and will not rust or corrode and are nonconductive. Two rows of teeth ensure a strong bond that will not vibrate loose. No tools are needed for installation, and the clamps are reusable. Sizes range from 1/4 to 4 1/4 in. nominal OD.
