Precision Brand 47045 Worm Gear Hose Clamp 9/16 in 4 Pack

Product Description

The PRECISION BRAND 47045 is a worm gear hose clamp sold in a 4-piece pack, designed for securing hose connections in plumbing, HVAC, and general mechanical applications. The BAND ALL 300 series uses a worm-drive screw mechanism to apply even radial clamping force around a hose or fitting. The 9/16-inch band width provides a broad seating surface that distributes load and reduces the risk of hose deformation under torque. These clamps are a standard go-to for techs working on coolant lines, drain connections, flexible ducting, and similar soft-hose assemblies where a secure, adjustable seal is required.

These clamps are suited for residential and light commercial installations where flexible hose connections need a reliable mechanical seal. Typical applications include HVAC condensate drain lines, plumbing supply and drain hose fittings, hydronic system flexible connectors, and equipment coolant lines. The 4-piece pack format makes this a practical choice for service calls where multiple connections are being made or replaced in a single visit. The model designation HD6SN corresponds to the BAND ALL 300 product family within the PRECISION BRAND clamp line.

Key Features

• Worm gear drive mechanism provides adjustable, even clamping pressure around the hose circumference
• 9/16-inch band width distributes clamping load to reduce hose damage risk
• BAND ALL 300 series construction suited for general-duty mechanical and trade applications
• Sold as a 4-piece pack, minimizing per-unit cost on multi-connection jobs
• Compatible with standard worm gear clamp installation tools and drivers

Compatibility

Designed as an OEM-style replacement or standard-fitment worm gear hose clamp for use on flexible hose connections in HVAC, plumbing, and general mechanical systems where a 9/16-inch band-width clamp is specified.

Installation Notes

Worm gear hose clamps are installed by plumbers, HVAC technicians, and pipefitters using a standard flat-head or hex driver. Before replacing or repositioning a clamp on a pressurized or fluid-carrying line, shut off the relevant supply valve and relieve system pressure. Do not overtighten the screw drive, as excessive torque can cut into soft hose material or strip the worm gear. Installations on potable water or gas-adjacent flexible connectors should comply with applicable IPC or IFGC requirements for the jurisdiction.
