Description
The Mishimoto High-Torque Worm Gear Clamp, part number MMCLAMP-WG-51HTBK, is a black-finish, stainless steel worm gear clamp engineered to secure hoses, couplers, and pipes with an outer diameter between 1.06in and 2.01in (27mm to 51mm). Built with a premium-grade stainless steel band and a steel spring, this clamp is part of Mishimoto’s Fabrication category and is designed to handle the demands of engine bay heat, moisture, and vibration while keeping connections tight.
As a Mishimoto Fabrication product, this high-torque worm gear clamp uses a simple worm gear design that allows for quick, easy tightening with a standard driver, making it a practical solution for anyone assembling or servicing hose and coupler connections. The stainless steel construction is intended to resist corrosion longer than typical zinc-plated clamps, helping the clamp maintain a tight seal over time. Each unit is reusable, and the clamp has a recommended tightening torque of 35 in-lbs (4 NM) to help achieve a proper seal without over-tightening the band. Sold in a pack of 10, this clamp size is also available in natural and gold finishes for builders who need to match components or simply prefer a different look, and it carries the Mishimoto Lifetime Warranty.
Vehicle Applications
This clamp is a universal fabrication component rather than a vehicle-specific part, sized to fit any hose, coupler, or pipe with an outer diameter within the 1.06in-2.01in (27mm-51mm) range. That makes it suitable for a wide variety of automotive fabrication and hose-clamping projects wherever a connection in this diameter range needs to be secured, from custom hose runs to coupler installations.
