Value Collection BDNA--24127-1 Worm Gear Clamp Sae 72

Product Description

The VALUE COLLECTION BDNA--24127-1 is a worm gear clamp designed for securing hoses, ducting, and flexible tubing in HVAC, plumbing, and general mechanical applications. Built to SAE Size 72 standards, it accommodates a clamping range of 4-1/8 inches minimum diameter to 5 inches maximum diameter. The band is 1/2 inch wide and constructed from stainless steel throughout, providing corrosion resistance in wet and outdoor environments. This clamp is installed by HVAC technicians, plumbers, and pipefitters who need a reliable, adjustable fastening solution for round pipe and hose connections.

This worm gear clamp is suited for residential and light commercial applications where a secure, adjustable band clamp is required on hose or duct connections in the 4-1/8 to 5 inch diameter range. Common install scenarios include connecting flexible drain lines, coolant hoses, HVAC duct collars, and exhaust tubing where vibration resistance and a tight seal are needed. The stainless steel construction makes it appropriate for installations exposed to moisture, mild chemicals, or elevated temperatures.

Key Features

• SAE Size 72 worm gear clamp with a clamping range of 4-1/8 to 5 inches
• Stainless steel band and housing for corrosion resistance in wet or outdoor environments
• 1/2 inch wide band distributes clamping force evenly across the hose or duct surface
• Worm drive mechanism allows precise torque adjustment with a standard screwdriver or nut driver
• Reusable and adjustable for repositioning or removal during service calls

Compatibility

Designed as a standard worm gear clamp for hose, duct, and tubing connections with an outer diameter between 4-1/8 inches and 5 inches, conforming to SAE Size 72 specifications.

Installation Notes

Installation is performed with a flat-blade screwdriver or a 5/16 inch hex nut driver. Ensure the hose or duct is fully seated on the fitting before tightening the clamp. Do not overtighten, as excessive torque can damage the hose material or deform thin-wall tubing. Follow applicable codes such as the International Mechanical Code or manufacturer hose assembly guidelines for the specific application.
