Description
The Mishimoto Constant Tension Worm Gear Clamp, MPN MMCLAMP-CTWG-105, is a 3.27in–4.13in (83mm–105mm) stainless steel worm gear clamp built with a steel spring on the adjustment bolt so it keeps pushing back against heat cycling instead of loosening off over time. It’s part of Mishimoto’s Fabrication lineup, engineered for shops and DIY installers who need a dependable clamp that holds its bite through repeated temperature swings.
Unlike a standard worm gear clamp, this constant tension design uses its integrated spring to maintain steady clamping pressure even as the hose or pipe underneath expands and contracts with heat, which helps keep couplers and connections sealed as tightly as the day they were installed. The stainless steel band resists corrosion longer than zinc-plated clamps, making it a solid choice for coolant lines, intake pipes, and other fabrication tasks where a durable, reusable, high-quality clamp matters. The worm gear mechanism allows for quick, easy tightening with a standard tool, and because it’s rated Premium grade and reusable, it can be removed and reinstalled as needed during service work.
Vehicle Applications
This is a universal Mishimoto Fabrication clamp rather than a vehicle-specific part, so no particular make, model, or year is required for fitment. It’s sized to clamp any hose, coupler, or pipe with an outer diameter between 3.27in and 4.13in (83mm–105mm), making it suitable for coolant lines, intake pipes, and similar fabrication or repair jobs across a wide range of engine bays. Mishimoto also offers this constant tension worm gear clamp in other sizes to cover smaller or larger diameter lines.
