Product Description

The PRECISION BRAND 47953 is a collared screw hose clamp designed for secure hose connections across a range of plumbing, HVAC, and mechanical applications. The clamp features a safety-collared, hex-head screw that prevents the screwdriver from slipping during installation, reducing the risk of hose or fitting damage. The hex-head design accepts blade-type drivers, nut drivers, and socket wrenches, giving technicians flexibility on the job. The clamp adjusts to fit hose diameters from 1-5/8 inches to 3-1/2 inches, covering a broad range of common hose sizes encountered in the field.

This hose clamp is suited for residential and light commercial use in HVAC, plumbing, and general mechanical service work. It is appropriate for securing coolant hoses, drain lines, condensate lines, and similar flexible hose connections. The 1-5/8-inch to 3-1/2-inch adjustment range makes it a versatile choice for technicians who need one clamp style to cover multiple hose sizes on a single service call. Sold in packs, with a minimum order quantity of 10 units.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified mechanical contractors.
