Precision Brand 47815 Worm Gear Hose Clamp 1-1/16 to 2 Inches

Product Description

The PRECISION BRAND 47815 is a heavy duty worm gear hose clamp designed to secure hose connections across a broad range of service environments. The clamp features a 9/16-inch-wide band that provides a greater sealing area than standard narrow-band clamps, reducing the risk of leakage under pressure or vibration. The one-piece housing is free of spot-welds, which eliminates common failure points found in lighter-duty clamp designs. Sold in a 3-piece pack, this clamp suits plumbers, HVAC technicians, and mechanical contractors who need reliable, repeatable clamping performance on fluid and air lines.

This clamp accommodates hose outside diameters from 1-1/16 inches to 2 inches, making it suitable for a wide range of hose sizes used in automotive, plumbing, and heavy duty industrial applications. The worm gear drive allows precise tightening with a standard screwdriver or nut driver, and the wide band distributes clamping force evenly around the hose circumference to prevent deformation or blowout at connection points.

Compatibility

Designed as a heavy duty worm gear hose clamp for use on hoses with outside diameters between 1-1/16 inches and 2 inches across automotive, plumbing, and industrial applications.

Installation Notes

Installation is typically performed by plumbers, HVAC technicians, or mechanical tradespeople using a flat-head screwdriver or 5/16-inch hex nut driver. Depressurize and drain the line before removing or installing hose clamps. Position the clamp band fully over the hose and fitting before tightening to ensure even seating. Do not overtighten, as excessive torque can damage the hose or strip the worm gear housing.
