Precision Brand 47809 Worm Gear Hose Clamp 3/8-7/8 in

Product Description

The PRECISION BRAND 47809 is a heavy duty worm gear hose clamp built for reliable, high-strength hose sealing across a wide range of service applications. Featuring a 9/16-inch band width, this clamp delivers a greater sealing area than standard narrow-band designs, reducing the risk of hose slippage or leakage under pressure. The one-piece housing is free of spot-welds, eliminating weak points that can lead to clamp failure in demanding service conditions. At 0.04 pounds, the 47809 is compact and easy to handle. It is designed for technicians and tradespeople who need a dependable, reusable clamp that installs quickly with common hand tools.

This worm gear hose clamp is suited for automotive, plumbing, and heavy duty industrial applications. Its clamping range of 3/8 inch to 7/8 inch makes it appropriate for small-diameter hose connections found in coolant lines, fuel lines, low-pressure water supply lines, and light pneumatic fittings. Residential and commercial plumbers, HVAC technicians, and automotive service professionals all use this style of clamp as a go-to fastener for securing flexible hose to barbed or slip fittings. This product is sold in a minimum quantity of 10 per pack.

Installation Notes

Worm gear hose clamps of this type are typically installed by HVAC technicians, plumbers, and automotive service professionals using a flat-blade or hex-drive screwdriver. Before installation, shut off fluid flow and relieve any pressure in the line being serviced. Position the clamp over the hose before seating the hose on the fitting, then tighten the screw evenly to achieve a uniform seal without overtightening, which can damage soft hose materials.
