hose clamps

Ellis Kinney · Jul 26, 2020

I am trying to order some T bolt hose clamps and do not know whether to use the inside or outside diameter of the hose. On some websites the measurements go
from say 2.1 to 2.25 which isn't much. I am specifically looking for a clamp for a 2 inch hose which is 2.25 outside dia. Thanks, Ellis

Go by the outside diameter of the hose with the hose on the fitting.

Try to get clamps that are in the middle of that measurement.

I'm switching over to using wire clamps when I can. Don't have to worry any more about keeping lots of sizes on hand, or if they'll hold tight enough, or whether they will rust. I plan to use some electric fence wire that I have, but it 'should' be a bit heavier wire.

Here's a video on those type systems. There are several styles that one can make. I'm working on something slightly different than anything else I've seen. Progress is slow because the mosquitoes are worse this year than I've ever seen, and I don't have a shop to work in. My shop is the great outdoors.

That is pretty cool sir. I think I am
going to look into it a little more
myself. Thanks for the information.

That works good when you have hose and pipe in vice with nothing in the way of you rotating the tool 180* to finish up the clamping. I think in most cases in the real world it won't work or as least work without fiddling with it a lot. I for years have used safety wire and safety wire pliers to tighten wire around hose.

Thank You, Ellis

there is a cheaper homemade alternative that works exactly the same way. Its made from a turnbuckle and well documented on Youtube when searching for "Clamptite". I've made it and used it before and it really does work well

after watching this video I realized all you can see is the back of the guys hand.. there are other videos on youtube that give you a better view. john

I was wondering the same thing. How in the world you would do that between the fan and water pump on a Farmall M tractor? Ellis

As far as I know, hose clamps have almost been completely phased out, especially in the automotive industry.

Hose clamps have basically one pressure point, they don't "slip" around pipe due to the thread cuts in the band part, on plastic male fittings with the hose over them they will crush or split the plastic. On pneumatic or hydraulic fittings, they'll loosen and leak.

I've changed over to crimpable bands, the ones commonly used in automotive and poly pipe situations. Kits with various sizes are available at Amazon and other sites.

For clamps always use the outside diameter of the hose, the surface that the clamp is actually in contact with.

As you say the T-bolt clamps don't have a very wide size range compared to the worm gear style. But, they are vastly superior for providing an even clamp pressure around the entire perimeter. It is better to error on the side of the clamp being slightly small rather than too big. If the clamp is on the small side you can remove the nut and open the clamp up larger then gently squeeze it together to get the nut started again for tightening. On the other hand once the nut bottoms out the clamp is as tight as it can ever be so you don't want it oversized.
