Rounded edges, polished surfaces, and concealed threads limit bacteria growth on these hangers. Use them to hold pipe in environments with frequent washdowns, such as food and pharmaceutical plants. They resist corrosion in wet environments and stand up to frequent washdowns with harsh cleaners and sanitizers. The FDA compliant cushion is safe for direct contact with food. It fits tightly around lines to damp vibrations that cause disruptive noises or damage to equipment. It also prevents corrosion caused by metal-to-metal contact. Mount these pipe hangers by twisting a threaded rod through the threaded hole on top.
