Midland Industries 620116 Worm Gear Clamp 5-3/4 in Ss

Product Description

The MIDLAND INDUSTRIES 620116 is a worm gear clamp from the 620 Series, designed for secure, adjustable clamping in plumbing, HVAC, and general mechanical applications. Built with a stainless steel band, housing, and screw, this clamp resists corrosion in wet and high-humidity environments. It covers a clamping range from 5-3/4 inches minimum to 7-3/4 inches maximum diameter, making it suitable for a wide range of hose and fitting sizes. The 1/2-inch-wide band and single 5/16-inch bolt drive provide controlled, even compression. Rated to SAE 116 specifications, this clamp meets industry standards for worm-drive hose clamp performance and dimensional consistency.

The 620116 is used in residential and light commercial installations wherever a reliable hose-to-fitting seal is required. Typical applications include ductwork connections, coolant hose assemblies, drain line fittings, irrigation lines, and general-purpose piping. The stainless steel construction makes it appropriate for outdoor, wet, or corrosive environments. Plumbers, HVAC technicians, and general mechanical contractors commonly install this clamp type on flexible hose, rubber couplings, and similar connections requiring adjustable compression.

Key Features

• Clamping range from 5-3/4 inches to 7-3/4 inches in diameter
• Stainless steel band, housing, and screw for corrosion resistance
• 1/2-inch-wide band for even load distribution across the clamping surface

Compatibility

Designed as an OEM-style and general-purpose replacement worm gear clamp for hoses and fittings with an outside diameter in the 5-3/4 inch to 7-3/4 inch range across plumbing, HVAC, and mechanical systems.

Installation Notes

Installation is typically performed by plumbers, HVAC technicians, or general mechanical trades using a standard flat-head or nut driver sized for a 5/16-inch bolt head. Always ensure the hose or fitting is fully seated before tightening the clamp. Do not overtighten, as excessive torque can cut into rubber or flexible hose material and compromise the seal. Power down or depressurize any system before removing or replacing a clamp on an active line.
