Description
The Mishimoto Constant Tension Worm Gear Clamp, part number MMCLAMP-CTWG-54, is a 1.26in-2.13in (32mm-54mm) stainless steel worm gear clamp built specifically to handle high-temperature clamping duties. Unlike a standard worm gear clamp, this one uses a spring-loaded adjustment bolt that keeps exerting pressure as temperatures cycle up and down, so the seal you set on install day doesn’t loosen over time.
This is a piece of practical Mishimoto Fabrication hardware designed to secure pipes, couplers, and hoses in demanding under-hood environments. The constant tension spring on the adjustment bolt is what sets it apart from ordinary clamps: as materials expand and contract with heat, the spring compensates and maintains steady clamping force instead of letting the band go slack. Add in a worm gear design for quick, controlled tightening and a stainless steel band and housing that resist corrosion far better than zinc-plated alternatives, and you get a clamp built to hold up season after season in coolant lines, intake pipes, and similar fabrication applications.
Vehicle Applications
This clamp is a universal-fit fabrication component rather than a model-specific part – it’s built to secure any hose, pipe, or coupler with an outer diameter between 1.26in and 2.13in (32mm-54mm), making it suitable for coolant lines, intake pipes, and comparable engine bay plumbing across a wide range of vehicle builds and custom fabrication projects.

Frequently Asked Questions
What size hoses or pipes does this clamp fit?
This Mishimoto constant tension worm gear clamp fits outer diameters from 1.26in to 2.13in (32mm to 54mm).
What is this clamp made of?
It is made from stainless steel with a steel spring, offering corrosion resistance longer than zinc-plated clamps.
Why use a constant tension worm gear clamp instead of a standard clamp?
The spring on the adjustment bolt allows the clamp to exert continuous pressure through a wide range of temperatures, helping keep parts clamped as strong as the day they were installed.
Is this clamp reusable?
Yes, according to Mishimoto’s specifications this clamp is reusable.
What is the recommended tightening torque for this clamp?
Mishimoto recommends a tightening torque of 14 lb-ft (20 Nm) for this clamp.
Does this clamp include a warranty?
Yes, it is backed by the Mishimoto Lifetime Warranty.
