Description
The Mishimoto MMCLAMP-CTWG-117 is a 3.74in – 4.61in (95mm – 117mm) constant tension worm gear clamp built from stainless steel and engineered with a spring-loaded adjustment bolt that keeps exerting pressure even as temperatures swing. Part of the Mishimoto Fabrication lineup, this clamp is designed for the moments when a standard worm gear clamp can’t keep up with heat cycling, ensuring your pipes, couplers, and hoses stay sealed as tightly as the day you installed them.
Where many clamping solutions rely purely on band tension, this constant tension worm gear clamp uses a steel spring on the adjustment bolt to maintain continuous clamping force through a wide range of temperatures — a key advantage in high-heat environments where metal expands and contracts. Its worm gear design allows for quick, easy tightening, while the stainless steel construction is built to resist corrosion longer than typical zinc-plated clamps. As part of Mishimoto’s broader family of constant tension worm gear clamps available in multiple sizes, this 3.74in – 4.61in (95mm – 117mm) option is suited for a variety of clamping needs, from coolant lines to intake pipes, and is backed by the Mishimoto Lifetime Warranty.
Vehicle Applications
This is a universal-fit Fabrication component rather than a vehicle-specific part, sized to secure pipes, couplers, and hoses with an outer diameter between 3.74in and 4.61in (95mm-117mm). It’s intended for builders and technicians working on coolant lines, intake pipes, and similar plumbing where a durable, heat-tolerant, reusable clamp is needed, regardless of make or model.
