Precision Brand 47814 Worm Gear Hose Clamp 3/4 to 1-3/4 Inch

Product Description

The PRECISION BRAND 47814 is a heavy duty, three-piece worm gear hose clamp designed for secure, leak-resistant connections across a wide range of fluid-handling applications. The 9/16-inch band width delivers a larger sealing footprint compared to standard-width clamps, reducing the risk of bypass leaks under pressure or vibration. The one-piece housing is manufactured without spot-welds, eliminating a common failure point found in lighter-duty alternatives. Licensed plumbers, HVAC technicians, and industrial mechanics reach for this clamp where a standard duty unit is not sufficient for the load or environment.

This clamp fits hose outside diameters ranging from 3/4 inch to 1-3/4 inches, making it suitable for coolant lines, radiator hoses, PVC fittings, compressed-air connections, and general plumbing tie-ins in both residential and commercial settings. The design also suits automotive and heavy-duty industrial assembly work where vibration resistance and a positive seal are required. The clamp is sold in a minimum pack quantity of 10 units.

Key Features

• 9/16-inch band width provides greater sealing area than standard narrow-band clamps
• One-piece housing construction with no spot-welds for improved structural integrity
• Clamp range spans 3/4 inch to 1-3/4 inches for versatile fitment across hose sizes
• Heavy duty rating suitable for automotive, plumbing, and industrial applications
• Three-piece worm gear design allows precise, tool-driven tightening

Compatibility

Designed for use on hoses with an outside diameter between 3/4 inch and 1-3/4 inches. Suitable for automotive coolant and radiator hose, plumbing supply and drain fittings, and general-purpose heavy duty industrial hose connections.

Installation Notes

A flat-blade or hex screwdriver is used to drive the worm gear screw to the required clamp tension. Shut off fluid supply and depressurize the line before removing or installing any hose clamp. Do not overtighten to the point of hose deformation, and confirm the band is seated squarely on the hose before final tightening. Follow applicable plumbing or mechanical codes for the jurisdiction and application type.
