Precision Brand 47951 Collared Screw Hose Clamp

Product Description

The PRECISION BRAND 47951 is a collared screw hose clamp designed for secure, damage-free clamping across a wide range of hose diameters from 1-1/8 inches to 3 inches. The defining feature is its safety-collared, hex-head screw, which prevents the screwdriver from slipping and cutting into the hose during installation or removal. This clamp is suited for plumbing, HVAC, and general fluid-handling applications where a reliable, tool-versatile fastener is required. It is installed by licensed plumbers, HVAC technicians, and mechanical contractors working on hose connections in both residential and light commercial settings.

This clamp is appropriate for use on rubber hoses, silicone hoses, and flexible tubing in fluid transfer, coolant, and ventilation applications. The combination collared and hex-head screw design allows the clamp to be driven with a flat-blade screwdriver, a nut driver, or a socket wrench, making it adaptable to confined spaces and varying tool access conditions. It is sold in packs with a minimum quantity of 10 units per order.

Compatibility

Designed as an OEM-style replacement or aftermarket hose clamp for residential and light commercial plumbing, HVAC, and fluid-handling systems where a collared screw clamp in the 1-1/8 inches to 3 inches range is specified. Also referenced as part CS40H.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified mechanical contractors. Shut off fluid flow and relieve system pressure before removing or replacing any hose clamp. Use the appropriate hex driver or socket to avoid rounding the screw head. Torque the clamp only to the point of a firm, leak-free seal without over-compressing the hose.
