Precision Brand 47819 Worm Gear Hose Clamp 2-1/16 to 3 in

Product Description

The PRECISION BRAND 47819 is a heavy-duty, three-piece worm gear hose clamp designed for secure, leak-resistant connections on hoses and fittings. It features a 9/16-inch-wide band that provides a greater sealing surface area compared to standard narrow-band clamps, reducing the risk of liner damage and improving load distribution across the hose. The clamp spans a clamping range of 2-1/16 inches to 3 inches, making it suitable for medium-to-large diameter hoses. The one-piece housing eliminates spot-welds, which are a common failure point in lower-grade clamps. Technicians in automotive, plumbing, and heavy industrial settings install this clamp where vibration, pressure, or demanding service conditions require a more robust fastening solution.

This clamp is appropriate for use in a wide range of applications including automotive cooling and intake systems, residential and commercial plumbing connections, and heavy-duty industrial hose assemblies. The wider band and spot-weld-free housing make it a preferred choice in installations where standard duty clamps have historically failed under sustained load or temperature cycling. It is sold in minimum quantities of 10 per pack, which suits service shops and contractors stocking for recurring installation needs.

Key Features

• 9/16-inch-wide band increases sealing area and reduces hose liner stress

Compatibility

Designed as a heavy-duty worm gear hose clamp for general use across automotive, plumbing, and industrial applications requiring a clamping range of 2-1/16 inches to 3 inches with a 9/16-inch band width.

Installation Notes

Worm gear hose clamps are installed by plumbers, HVAC technicians, and automotive mechanics using a standard flat-blade or hex-head screwdriver or nut driver. Before installation, ensure the hose is fully seated on the fitting and the system is depressurized and drained as appropriate for the application. Tighten the screw evenly to secure the clamp without over-torquing, which can deform the hose liner. Follow applicable codes such as IPC or IFGC for plumbing and gas-line hose connections.
