T Bolt Clamps
 

I thought T bolt clamps were better then worm clamps and they would last longer. So far two of these have broken the same way. Appears to be metal fatigue. It came off my 08 truck but same things are used on boats. Was thinking of replacing them on the boat but after two I'm having second thoughts.

Depends on the brand. We use T-Bolt clamps in manufacturing of motorcycle exhausts. Five Star or Breeze have worked very well for us. Have tried many others, nothing seems to work as good or lasts as long.

Rob, any thoughts on RG Ray or Clampco out of wadsworth?

Things that bother me is most worm clamps start to leak a bit, but these just break all at ones. The crack is very small in nature, don't know if I would have noticed with regular inspections

Have not compared those on our applications, Clampco has been marketing Marine T-Clamps, is that the brand AllDodge has in the above photos?

No, these are Mopar/Chrysler but its just that how can you tell when there going to fail.

What size you need I can send you some, I know a guy

Appreciate that, but already replaced all of them on my truck with ones from NAPA. Guess if I do go the route on the boat I'll contact you. Have only had a couple problems with the worm clamps and there always the ones that get removed every so often for maintenance.

I have been using them on all my many boat's exhaust for years. I do get mine from a local hydraulic shop. The one thing I do not like about them is the the T bolt or nut seems to strip out pretty easy. Never going on, always taking off.

I've never seen them break line that. Interesting. I messed one up royally (threads) a while back when replacing the trim indicator cables. I bought a cheapy from Advance Auto to hold me over that rusted immediately but still held the drive indicator on just fine. I replaced it with some I bought from Amazon and I thought they were great quality. To my knowledge (boat now sold) they are still fine. Just my experience.

I had an exhaust clamp (v groove style) break on me like that on 575sci e-tops. To my knowledge, it was a factory Merc piece - lasted 15 years before it just snapped one day.

RG Ray is what I bought off of Amazon. And I think those were the original clamps on my drive indicators too.

RG Ray and Clampco comes from the factory on large heavy equipment of the Yellow variety. We have good luck with them.

Good info, thinks guys.

Since I never had a worm clamp fail out right (fresh water), might just stick with them. Don't know will give it some thought

There are some other options out there:

Are you running a really high PSI turbo setup?

No, stock 6.7 Cummins, think its around 20 sum psi under heavy load. I was pulling the boat up a long a steep hill when it gave out.

Oh, and those clamps are nice

You must have a Wednesday motor and turbo, and Friday/4:15PM clamps. :D

Good one :D

During my current resto' I've found and been told by suppliers of both that Awab clamps are more robust and have stronger clamping load.
