Cushion clamps specifically for metric pipe sizes, the Hydra-Zorb clamps guard against shock, vibration and corrosion and they are made in-house in the U.S. These clamps are available in the U.S. and Canada in sizes supporting piping from 6 mm to 160 mm, and can be supplied with mild-plated steel, aluminum or 304/316 SS clamp straps. The cushion material is rated -65 to 275 F, and the clamps are UL flame/smoke 25/50 certified for use in plenums. High-temperature cushion material is available upon request. Aquatherm.
