Uniquely designed fasteners in an extensive new line of double-grip hose clamps feature a double-tooth interlocking jaw for exceptional strength. Quick and easy to install with sizes ranging from ¼ to 2 ¾ in. (6.35–69.85 mm) to accommodate most applications, they are molded in durable black Nylon 6/6, making them corrosion-resistant with good chemical resistance. An overlapping tapered ring is fastened around the hose or tubing and secured to the required tightness by compressing the double-gripping interacting graves in a ratcheting fashion, creating a tight sealing application. Clamps can be removed by separating the clamping halves in a perpendicular direction at the seal. The manufacturer recently released its 270-page catalog #38 featuring 19 new product lines with 359 new items added.
