Your cart is empty. Just like our high-torque worm gear clamps, Mishimoto’s Constant Tension Worm Gear Clamps are an effective solution to a wide range of clamping needs. Where this 1.26” – 2.13” (32mm – 54mm) constant tension worm gear clamp excels, however, is in high-temperature applications. The spring on the adjustment bolt allows the clamp to exert continuous pressure through a wide range of temperatures to ensure your parts stay clamped as strong as the day you installed them.
This 1.26” – 2.13” (32mm – 54mm) constant tension worm gear clamp is made from stainless steel to weather any environment and ensure a tight seal for years to come. Our constant tension worm gear clamps are also available in a wide variety of other sizes to suit everything from coolant lines to intake pipes. Like all Mishimoto products, this 1.26” – 2.13” (32mm – 54mm) constant tension worm gear clamp is backed by our Mishimoto Lifetime Warranty.

It's a gold clamp gains atleast 20+ HP as opposed to the boring silver/chrome ones. All jokes aside. Does what it's advertised to do. My silicone hose attached to my turbo popped and the clamp stayed in place without losing tension.

These are the best quality worm clamps in the market that I have come across so far. Mishimoto truly manufactures components like OEM. They are sturdy. With the zinc-plating they don't rust. And the belleville springs maintain constant tension in hot and cold.My master mechanic likes them, because they don't need to be periodically checked for tension (like the spring-less ones do). Since I installed these last year, the intercooler pipes never had any vacuum leaks (knock on wood!).

The picture indicates a constant spring tension clamp at a price that about half of what it should be. But when the box of 4 arrived it was a stacked set of washers that looks like a spring clamp. But I needed them right now so I tried to use tone but the mechanism is so bound it was impossible to turn by hand, I had to use a power tool. I finally got it on, looked at it and realized two things: If I ever had to remove it away from the shop I couldn't do so without a power tool- and second it looked idiotic on the hose, a gold colored hose clamp with a stack of thick washers between the nut and the clamp. Once again inoperative imitative inexpensive junk from China. Back it goes. This time I learned my lesson.

Used for car coolant hoses. Application was irritating at first. If you remove the clip from the center, you have to turn the bolt to loosen before re-inserting it and the teeth will catch that way. Leaks are gone and these are very heavy duty. Amazing.

Holds well and feels secure, recommend you use with a lower torque impact as using a wrench may be tough

They did cut down on leak from rad hose but there is still a small leak

Pretty sturdy, by far one of the best worm clams only second to T bolt clamp. But it is pretty expensive and also bulky.

I bought one of those chinese knockoff aluminum radiators, and the outlet pipe is a little too small for the radiator hose and no matter what style clamp I used it still leaked. I bought this one because it looked heavy duty, and so far no leak! I've tried regular clamps, crimp clamps, t-bolt clamps.. nothing worked. So hopefully we don't have any more leaks, because I really didn't want to change the radiator again!

No matter how I adjust this clamp it leaks. The backside of the worm housing is too thick and creates two gaps between the clamp and the hose and an incomplete seal. As you can see pink coolant is seeping out of the hose. Input from Mishimoto is welcome! Otherwise these were a waste on hard earned money.

Many moons fighting with non adjust spring clamps on opv but if possible always use these type on my own. Why? Unless you have an older open bay engine you will encounter situations where it’s near impossible to get fancy tools to work and yes got knipex, got lisle, so, all good tools but when it s 100 above or 25 below and you need it done, with out lifts, wherever, its mighty convenient to turn that 10 mm screw . Tighten up ,look for clamp indent on hose and your good. Thesetypes tend to adjust for expansion contraction . Used other brands and I’ll give these a try. Just look for the hose S you never ever want to fight with. A Note on old worm clamp wo tension adjust , still ok for rubber to metal fitting but these type are necessity if any plastic fittings are involved . Easy access areas just leave Oem stuff they come off easy even with channel locks. I’ll edit if any issue. Edit! no info on torque settings !, these need 7-8 lb torque ,place screw for easy access above below etc. Because Had to do in stages . May be ok product but this is a bit much 3 star . Indicate torque on install etc or don’t sell these . Breeze Carr,gates, neverhad issues like this. This aggravation negates benefit for ordinary customers at best! at worst? Update year on: you will need to re tighten 1-2 turns they will weep. Always Ensure you have easy access on rad hose to check and snug up. On the vehicle involved a long access extention set up from the top to lower rad hose allows easy checks and is a good idea for all installs of screw on clamps and constant tension alike with plier use also . But as noted have not seen this in other brands. Might consider change out doin this way too long so if constant maintenance is your bag these are for you! But if your old like me or just want to do things right once maybe look elsewhere. A final note: this is especially annoying when I occasionally see other past change outs done that are still going strong after 5-10 years different brands min you and you wonder , hmm.
