Precision Brand 47817 Worm Gear Hose Clamp 1-9/16 to 2-1/2 in

Product Description

The PRECISION BRAND 47817 is a heavy-duty, three-piece worm gear hose clamp designed for secure, reliable hose connections across a wide range of applications. The clamp features a 9/16-inch wide band that provides a greater sealing area compared to standard narrow-band clamps, reducing the risk of leakage under pressure or vibration. The housing is constructed as a single piece and is free of spot-welds, which eliminates weak points that can cause premature failure in demanding service conditions. Licensed tradespeople and experienced service techs working in automotive, plumbing, and industrial settings will find this clamp well-suited to their needs.

This clamp covers a clamping range of 1-9/16 inches to 2-1/2 inches, making it appropriate for medium-diameter hose connections in residential and commercial plumbing systems, automotive cooling and intake lines, and heavy-duty industrial fluid transfer applications. The worm gear drive allows precise tightening and easy adjustment during installation or service.

Key Features

• 9/16-inch wide band for increased sealing area compared to standard clamps

Compatibility

Designed for use with medium-diameter hoses in automotive, plumbing, and heavy-duty industrial applications where a clamping range of 1-9/16 inches to 2-1/2 inches is required.

Installation Notes

Installation is performed with a standard flat-blade or hex-drive screwdriver depending on the screw head type. Shut off fluid flow and relieve any system pressure before removing or installing hose clamps. Tighten the worm gear screw evenly to seat the band uniformly around the hose without over-compressing the hose wall. Follow applicable plumbing or mechanical codes for the installation environment.
