Hose clamps

Are there any good hose clamps out there? Put some brand new ones on from Autozone and they keep backing off. Total garbage anymore. I talked to a mechanic recently and he they sometimes double up on the clamps because of this problem.

I'm talking about radiator hose clamps.

I have not been making/maintaining hoses for the last five years but before that I made hundreds with Tridon hose clamps without having that problem. Most were hot water or air at 50-100psi but most were not subjected to extreme vibration. The better choice is the "lined" stainless steel clamps. A lined hc is the only choice for silicone hoses as the slots damage the hose.



For radiator hoses I have been replacing hose clamps with factory spring clamps as they are much wider. This is what they are trying to copy when:

If the spring clam is undamaged it seems to hold without leaks or adjustment. They have been trouble free on my truck for over 25 years and 22+ on some daily drivers.(Tougher than the radiator)

Agree with Z09. Factory spring clamps are the best because they apply equal pressure
all the way around the hose whereas a screw clamp applies most pressure on the screw side
of the clamp. Screw type clamps also tend to dig into and tear up the hose.

Agreed! worm gear clamps suck and even worse nowadays with all cheapnese ones that are really bad.
When I replaced all the hoses on mine after buying it I put spring clamps back on every connection. Had to hit the boneyard for some donors but not a single leak.
Have even removed/reinstalled a few for opti work and still no leaks/problems.

I never use the worm clamps on anything unless in a pinch.

They've got heat shrink hose clamps out for a while now - Something else to consider

I use stainless steel T-Bolt clamps and have never had an issue with them. Be sure to get the 100% stainless ones, not the ones with steel nut/bolt that rust together.

I've found that Silicone Intakes have full stainless ones for reasonable cost

I'm going to try what Fix has shown here.^^^^^^^^^ The Gates clamps. There have been past posts about them and they seem to be a good deal. They just have a cleaner look about them too.

Can't say I've heard of worm gear clamps loosening up on their own before but there are some cheap clamps out there. When going with Green hoses, I spent some money on quality Stainless Lined Clamps I got from MSC catalog. Little pricey compared to the parts store crap but never an issue with them. You can tighten worm gear type clamps too much which can cause the clamp to come apart and they don't clamp good after that.

'95 Caprice SS conversion - Bonny Buckets - 96 Column, Shifter and Console - 3.73 Gear and Herter tune - Z/28 Cluster - Blazer OH Console - Green/Pink bushings - Chromed Impala Wheels - Eibach Springs and Bilstein Shocks - Corvette Engine Dress - the list goes on and still more to do...it never ends.

Thanks for the replies! These are just standard hoses not the green hoses. Going to check the boneyards this weekend and if nothing, going to buy the ss t-clamps.

spring type clamps

When I first started working on cars I hated spring clamps, now I'm liking them, and was thinking about getting an assortment box from Amazon. Anyone have any experience with any particular brand? And am trying to figure out sizing, like, what size works best for 5/8 heater hose?

It's been my experience for awhile that auto part store clamps are cheap chinesium junk, even if they're stainless only the band is and the screw mechanism is not and will still rust. If you want good stainless worm gear clamps, just hit your local hardware store (lowes, menards, etc.) and meander on back to the plumbing section, you should have no problem finding any size you could want in 100% stainless and they come in convenient bags of 10 or 20 or something like that. I keep a medium plastic tote full of them on hand so I never have to run and get one if I need it. So far I've had zero issues with them.


If you want to stick with the spring clamps, get a decent pair of spring clamp pliers, they're worth their weight in gold. There are two versions, I recommend the extended cable version, you can get that into darn near any place they stuck them and release them with ease. I found a pair that are made in France, so hooray for not being chinesium junk. On a side note, anyone know if those gates compression things are single use or can they be reused? I've seen them before but I thought they were single use only and for as often as I'm taking stuff apart to fix other things, I'd probably go through a ton of them.

This is this frenchie set that I bought, but I've literally never used the standard pliers looking one. Even if the clamp is easily accessible, inevitably it'll be clocked such that you can't get on them with that one anyways. The cable one works beautifully every time, so if that's available by itself I'd recommend it. I think it was also branded and sold under the Craftsman name at one time, because I came across some on ebay that were craftsman, looked identical and said made in France.

Something witty.
