Best exhaust clamps you can buy

worked great

Bought these when I started my trucking company and threw them in the truck. While going up a hill on I-20 west of Atlanta my truck lost power and I barely made up the hill. I popped the hood and saw the turbo hose has popped off and the clamp was gone. 5 minutes later I threw it on and was back on the road. That was 2 years ago, and it is still going strong.

Good clamp, well made. It did the job for me!

I bought these clamps to replace some regular hose clams for a drain waste splice/ repair of cast iron to pvc T. The regular clams were giving out. These new clamps are super strong. Be careful on the sizing of your order. The description of the size seemed off. I ordered the 3” and had to return them and order the 2.75”. I am very happy now.

Exactly what I needed. I was worried about what my measurements were, and how the chart was read, but I pulled the trigger on the exact size I needed, based on what the I.D. of the clamp is, and hit a home run! These clamps are much better quality than your general 'eBay intercooler kit' t-bolt clamps. If I have any more needs in the future for t-bolt clamps, I'm absolutely buying from both this seller, and company. I am happy that they use nyloc nuts, instead of using double-nuts. They have held up to several thousand miles, and haven't slackened-up even a fraction. I am running 19psi, and they have done nothing but performa! The value for money paid on these is excellent, you won't be disappointed in these at all!

I used them to mount fire extinguisher on a SXS worked great

solid clamps

As Described

Wouldn’t tighten up to 1 1/2” as advertised.

Not a advertised. These clamps at their tightest are not 4.5 inch but rather 4.625 and this fit to loose. Wasn't able to use them in the end. Waste of money
