Rotor Clamp, Inc. produces a line of self-compensating hose clamps for low-pressure applications in single wire, double wire, and constant tension band (CTB) and light band configurations. These clamps expand and contract with the hose in response to temperature changes in the application. They cannot be over- or under-tightened, and are installed and removed easily using either manual or pneumatic tools. Clamps also are a good alternative to gluing hoses to manifolds, providing extremely effective clamping without the use of messy glues that could potentially clog the hose line. The following guidelines should be considered when choosing a clamp style for an application.
Single wire clamps have the most effective holding force and clamping strength. The single wire concentrates the clamping force in one specific area around the hose. Single wire clamps can be used on such applications as household appliances (laundry machines, dishwashers, etc.), heating and air-conditioning systems and utility vehicles (lawn tractors, golf carts, etc.).
Double wire clamps are used where a lower clamping force than offered by single wire clamps is sufficient and aesthetics are important. The double wound wire spreads out the clamping force around the hose, and are more cost effective than single wire clamps. Applications include spa fixtures, appliances, heating and air-conditioning, and utility vehicles.
CTB clamps are used in applications where a lower clamping force than offered by single wire clamps is sufficient, but a higher clamping force than produced by double wire clamps is needed. CTBs are found in spa applications.
Other factors to take into consideration when choosing a clamp style include the size of the hose and fitting, whether gas or liquid will flow through the hose, and at what pressure. One should also take clearance into account to determine whether a clamp style will fit into the application. Products certified to ISO/TS 16949:2002.
