Precision Brand 47820 Worm Gear Hose Clamp 3-piece

Product Description

The PRECISION BRAND 47820 is a heavy duty, 3-piece worm gear hose clamp designed for secure, reliable hose connections across a wide range of trade and industrial applications. The clamp features a 9/16 inch wide band, which provides a greater sealing surface area compared to standard narrow-band clamps. The clamping range spans 2-5/16 inches to 3-1/4 inches, making it suited for medium-to-large diameter hose connections. The one-piece housing is manufactured without spot-welds, reducing potential failure points and improving overall structural integrity under vibration and pressure.

This hose clamp is appropriate for automotive, plumbing, and heavy duty industrial service. It performs well in installations where a broad sealing footprint is needed to prevent hose slippage or leakage under pressure. The worm gear drive allows for incremental tightening and precise torque control during installation. This clamp is sold as a 3-piece pack, with a minimum order quantity of 10 packs, making it practical for shop stock or fleet maintenance operations.

Compatibility

Designed as a heavy duty worm gear hose clamp for hose outer diameters from 2-5/16 inches to 3-1/4 inches, suitable for automotive, plumbing, and heavy duty industrial hose connection applications.

Installation Notes

Installation is typically performed by plumbers, HVAC technicians, or mechanical tradespeople using a standard flat-head or hex-drive screwdriver. Ensure the hose is fully seated on the fitting before positioning the clamp and tightening the worm gear. Do not overtighten, as excess force can cut into the hose material and cause premature failure. Verify clamp position and hose integrity before returning the system to service.
