Parker 97HC-12 Worm Gear Clamp 0.5 to 1.25 in Ss Band

Product Description

The PARKER 97HC-12 is a worm gear clamp designed for securing hose connections across a range of tube and hose diameters. It adjusts from 0.5 inches minimum diameter up to 1.25 inches maximum diameter, making it suited for a variety of pipe and hose sizes common in HVAC, plumbing, and fluid-handling installations. The band is constructed from stainless steel for corrosion resistance, while the worm drive housing is brass. The hex drive accepts a standard hex driver or nut driver, allowing fast tightening in tight spaces. This clamp is RoHS compliant and sold individually.

This clamp is used in residential and light commercial applications where hose-to-fitting or hose-to-pipe connections require consistent, reliable clamping force. Typical install scenarios include coolant lines, condensate drain lines, fuel lines, and general fluid-handling assemblies. The 0.5-inch band width distributes clamping load evenly across the hose surface, reducing the risk of cuts or blowouts on softer hose materials. Plumbers, HVAC technicians, and pipefitters regularly use worm gear clamps of this type when assembling or servicing flexible hose connections.

Key Features

• 0.5-inch band width for even clamping load distribution
• Hex drive size 0.31 inches — compatible with standard nut drivers and hex keys
• RoHS compliant

Compatibility

Designed as an OEM-style replacement or service clamp for flexible hose connections in the 0.5-inch to 1.25-inch outside diameter range, suitable for HVAC, plumbing, and general fluid-handling assemblies.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians using a standard nut driver or hex wrench matching the 0.31-inch hex drive. Shut off fluid flow and depressurize the line before removing or installing any hose clamp. Do not overtighten — apply only enough torque to seat the band firmly against the hose without deforming it. Ensure the hose is fully seated on the fitting barb before tightening the clamp.
