The Precision Brand QR-H series partial stainless steel quick release worm gear clamp has a stainless steel band and housing, a zinc-plated steel screw, and a mechanism that swivels to lock the clamp or disengage it for quick release. A worm gear mechanism adjusts the clamp’s diameter to precisely apply sealing pressure. The 1/2" band provides a secure sealing area. The band and housing are made of stainless steel that conforms to the Society of Automotive Engineers (SAE) 300 series standard and provides resistance to corrosion. The slotted, 5/16” hex-head screw allows installation using a blade screwdriver, nut driver, or socket wrench. The screw is made of steel that is zinc-plated for resistance to rust, and the bridge is made of SAE 400 series stainless steel for resistance to corrosion.
Hose clamps attach hoses to fittings to prevent flow leakage. They come in a variety of designs and distribute uniform pressure over the circumference of hoses to bind them to fittings.
