Product Details | HOSE CLAMP
4730-00-278-0427 A clamp in which the body (band or wire) completely encircles an item and distributes a relatively even amount of pressure throughout the entire 360 degrees (6.282 radians) of the periphery of the item to be compressed. Its compression quality is dependent upon an integral screw mechanism, (screw, bolt spring compression and the like mechanical fasteners), or it may be applied by a device not integral with the clamp itself. It is specifically designed to prevent leakage between a hose and its attaching connection(s) when the body of the clamp is round or circular. For square, rectangular, or irregularly shaped items, see CLAMP, HOSE, SPECIAL-SHAPED. Excludes CLAMP, ELECTRICAL; CLAMP, LOOP; CLAMP, FIRE HOSE, SHUTOFF; FERRULE (as modified); and HAND SCREW.

What Our Customers Say
Thank you very much for the excellent service and professional customer care.
The service was excellent. I can think of no improvements to date that you can make regarding internet sales.
The representative for WBParts was efficient & handled our request in a timely & professional manner.
Tried two other sources, neither of them responded, was all done online, never spoke to anyone.
The response is quick and the price is often very good. We are completely satisfied.
