WaveSeal 360 provides unique expansion and contraction to create a steady 360° seal in response to changing temperatures and works well with non-uniform hoses. Two inward pointed ridges form points of high pressure and between them a low pressure center that creates an O-ring effect. This stainless steel clamp has a 5/16 inch hex head screw and the 9/16 inch band width offers a greater sealing area. Commonly used with hydraulic, cooling and charged air systems.
