Precision Brand 47818 Worm Gear Hose Clamp 1-13/16 to 2-3/4 in

Product Description

The PRECISION BRAND 47818 is a heavy duty, 3-piece worm gear hose clamp designed for secure, leak-resistant sealing across a broad range of trade and industrial applications. The clamp features a wide 9/16-inch band that distributes clamping force over a greater surface area, reducing the risk of hose deformation and improving seal integrity. The housing is one-piece construction and is completely free of spot-welds, which eliminates common weak points found on lighter-duty clamps. This makes the 47818 well suited for demanding service environments where vibration, pressure fluctuation, or temperature cycling are factors. Plumbers, HVAC technicians, and mechanical contractors reach for this style of clamp when standard-duty hardware is not adequate for the job.

The PRECISION BRAND 47818 covers a clamping range of 1-13/16 inches to 2-3/4 inches, making it compatible with hose and fitting sizes commonly encountered in automotive cooling systems, plumbing supply and drain connections, and heavy duty industrial fluid transfer lines. The worm gear drive allows precise torque adjustment with a standard screwdriver or nut driver. Sold in a minimum quantity of 10 per pack, this clamp is a practical stocking item for service vans and shop inventory.

Compatibility

Suitable for use in automotive cooling and fluid systems, plumbing connections, and heavy duty industrial hose assemblies where a clamping range of 1-13/16 inches to 2-3/4 inches is required.

Installation Notes

Worm gear hose clamps of this type are installed by plumbers, HVAC technicians, and mechanical contractors using a standard flat-blade screwdriver or 5/16-inch hex nut driver. Relieve system pressure and shut off fluid supply before removing or replacing any hose clamp. Position the clamp band at least 1/4 inch from the end of the hose to ensure full seating on the fitting bead. Do not overtighten, as excessive torque can cut into hose material and compromise the seal.
