Stepless® Ratchet Clamps with a 360º Seal provide a superior seal on hose or tubing through their patented interlocking design by eliminating the leak path created by the over-lapping ring design hose clamps. As interlocking grooves are ratcheted together, the sealing diameter of the fastener is aligned in parallel, creating a uniform clamping surface. They are removable and reusable, with easy installation on most liquid, gas, or vacuum lines.
