Precision Brand 47949 Collared Screw Hose Clamp

Product Description

The PRECISION BRAND 47949 is a collared screw hose clamp designed for secure, damage-free hose connections in plumbing, HVAC, and general mechanical installations. The safety-collared, hex-head screw is the defining feature: it prevents the screwdriver from slipping off and gouging the hose during tightening. The clamp fits hose outside diameters from 1-9/16 inches to 2-1/2 inches and is sold in packs with a minimum order quantity of 10 units. Licensed tradespeople and experienced installers working with flexible hose connections will find this clamp straightforward to apply with standard hand tools.

This clamp is suited for residential and light commercial applications where a reliable, vibration-resistant hose connection is required. Typical use cases include HVAC condensate drain lines, plumbing supply connections, and equipment hose fittings within the 1-9/16-inch to 2-1/2-inch diameter range. The dual-drive design makes it practical in tight spaces where tool access is limited.

Installation Notes

Hose clamp installation on pressurized systems should be performed by a licensed plumber or HVAC technician following applicable IPC or IFGC guidelines. Shut off water or fluid flow and relieve system pressure before removing or replacing any clamp. Use a properly sized nut driver or socket wrench on the hex-head screw to achieve even clamping force without over-tightening, which can deform the hose. Inspect the hose surface for cracks or wear before installing a new clamp.
