Ideal 6420 Hy-gear Hose Clamp 3/4 to 1-3/4 in Series 64-0

Product Description

The IDEAL 6420 is a Series 64-0 Hy-Gear worm-drive hose clamp designed for secure hose and tube connections in plumbing, HVAC, and general mechanical applications. The clamp features a 9/16-inch-wide band constructed from 200-series stainless steel and a 3/8-inch hex head screw machined from 410 stainless steel. The worm-gear drive mechanism provides consistent radial clamping force across the full adjustment range. This type of clamp is routinely installed by plumbers, HVAC technicians, and pipefitters wherever a reliable, corrosion-resistant band clamp is required.

The IDEAL 6420 suits residential and light commercial installations involving hoses, flexible connectors, and tubing with an outside diameter between 3/4 inch and 1-3/4 inches. Typical applications include coolant hoses, drain connections, HVAC flex duct collars, and general fluid-transfer lines. The all-stainless construction makes it appropriate for wet or corrosive environments where carbon-steel hardware would degrade over time.

Key Features

• Adjustment range: 3/4 inch minimum to 1-3/4 inches maximum clamp diameter
• 200 stainless steel band resists corrosion in wet and outdoor environments
• 9/16-inch band width distributes clamping load evenly across the hose surface
• 410 stainless steel 3/8-inch hex head screw for use with standard hex drivers or nut drivers
• Series 64-0 Hy-Gear worm-drive design maintains torque and resists loosening under vibration
• Size 20 designation consistent with standard clamp sizing conventions

Compatibility

Designed as an OEM-style replacement or new-installation hose clamp for any application requiring a worm-drive band clamp with a clamping range of 3/4 inch to 1-3/4 inches.

Installation Notes

Install using a 3/8-inch hex driver or nut driver; a torque-limiting driver is recommended to avoid over-tightening and damaging the hose or band. Ensure the hose is fully seated on the fitting before positioning the clamp and tightening. Shut off fluid supply and relieve system pressure before removing or repositioning any existing clamp. Follow applicable plumbing or mechanical codes for the jurisdiction when used in permanent fluid-carrying systems.
