Inspect the new ones carefully. They should have a shot of lube grease at the screw interface.

Several posts mention expensive clamps failing at welds etc. what sort of warranty if any are they covered by? Seems lots of items now have "lifetime" Warranty.

Isn't also true to double clamp (regardless of clamp style) when practical?

Yes, if there is enough room on the hose barb for 2 clamps. If there isn’t enough room on the barb then putting 2 clamps on can be a bad thing and actually harm the hose.

They are pretty comparable to AWAB as far as I can tell, just a different manufacturer.

Mike:

This two part article describes the options in detail...

Part I: https://stevedmarineconsulting.com/h...and-selection/

Part II: https://stevedmarineconsulting.com/h...ation-and-use/

Solid, embossed hose clamps are preferred, however, lots of high end builders, along with engine manufacturers, continue to use the perforated automotive style clamps, they work but are not nearly as robust or long-lasting. While I don't recommend wholesale replacement of seemingly sound perforated clamps, if the screw is magnetic, they should definitely be replaced.

Tridon make no mention of warranty on their website that I found, though I do see mention of 60 days warranty on resellers sites.

Steve, I think “seemingly” is a key word there. I found a mix of clamps but also failure modes and only by setting out to change out the clamps did I find the bad ones. I didn’t do them all in one day but worked up from the most critical and secreted away to the less critical and “change during maintenance” ones. Not really a big investment in money terms but a big one in peace of mind. I also picked a few dodgy hoses and a couple of sea cocks that weren’t sealing in the process as well.

Agreed, looks can be deceiving, there's never any harm in upgrading clamps. From my perspective, as a consultant, if I'm inspecting a vessel I normally don't recommend wholesale replacement of perf. clamps unless I have reason to believe they are flawed, magnetic, corroded etc. But again, upgrading is good and if in the process you found other issues, that's even better. That reminds me of the Boat Genie in the Cigar Box story...
