Standard Nylon Ratchet Hose Clamps are based on the original design for this type of fastener. An overlapping tapered ring of nylon is fastened around the hose or tubing desired and secured to the required tightness by compressing interacting grooves in a ratcheting fashion, creating a tight sealing application. Clamps are reusable. They can be removed by separating the clamping halves in a perpendicular direction at the seal.
