• Heavy Duty: The buckle of our hose clamps is welded to increase breaking torque by 60%. The non-perforated band prevents deforming and stripping if over-torque. Our worm drive hose clamps provide superior clamping force and safe sealing. Failure torque: 65 lb-in, recommended installation torque: 40-45 lb-in.
• SAE Standard: These embossed hose clamps, designed by German, meet USA SAE J 1508 standards. The hex size of slotted screw head is 5/16" for nut driver fast installation! The British diameter range is stamped on band.
• Protect Your Hoses: The design of roll-up band edge and non-perforated band prevents soft hoses from cutting and extruding through the notches, especially for rubber and silicone hoses. The service life can be increased. Band width is 1/2"(12mm).
• All 304 Stainless Steel: The screw, band and buckle are made of premium 304 SS. To keep smooth worm drive, the stainless screw should be plated with a thin layer of zinc to prevent metal grinding and micro welding when hose clamp is torqued by electric screwdriver at high speed and heat is generated.
• Applications: Our heavy duty hose clamps are popular general purpose for garden sprinkler, pool, pond, drip irrigation water line, HVAC ductwork and engineered to prevent hose damage so ideal for auto, fuel injection line, gas line, heater and radiator hose.
