Precision Brand 47955 Collared Screw Hose Clamp

Product Description

The PRECISION BRAND 47955 is a collared screw hose clamp designed for secure, damage-free hose clamping across a wide clamping range of 2-1/8 inches to 4 inches. The safety-collared, hex-head screw is the defining feature: it prevents the screwdriver from slipping off and gouging the hose during tightening. The combination collar and hex-head design accepts both blade-type and nut drivers as well as socket wrenches, giving technicians flexibility in tight or awkward installation spaces. Sold in packs of 10, this clamp is a practical choice for plumbing, HVAC, and general mechanical service work.

This hose clamp is suited for residential and light commercial applications where a reliable, reusable hose clamp is needed. Typical uses include securing radiator hoses, coolant lines, duct connections, and similar flexible hose assemblies. The wide clamping range of 2-1/8 inches to 4 inches makes it adaptable across multiple hose sizes without stocking multiple clamp sizes. Plumbers, HVAC technicians, and mechanical service professionals will find the hex-head drive particularly useful when working in confined areas where a standard flat-blade clamp is difficult to turn.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or qualified mechanical service professionals. Before installing or replacing a hose clamp, shut off fluid or air flow to the line being serviced and relieve any system pressure. Use a nut driver or socket wrench on the hex-head screw for controlled, even tightening without over-torquing the clamp band. Inspect the hose for wear or cracking before re-clamping to ensure a proper seal.
