I ordered this one, haven't used it yet but it keeps you from carrying a million different size clamps onboard and produces a nice smooth clamp.

AWB works and is not as pricy as others.

You need an accurate estimate of the size required.

The clamptite is in our toolbox as an EMERGENCY system , as once used there cut off and need to be remade.

Tim, why are you replacing all your hose clamps - are they looking nasty, or is this part of scheduled maintenance?

I'm also a firm believer in the AWAB clamps that RC at Compass Marine advocates for (RC is a great guy with a ton of knowledge). We replaced just about all the old clamps with AWAB on our sailboat. At that time, Defender had the best prices. Another good source is the store at sailboatowners.com Awab Clamps: Hose Clamps

The are expensive, but worth it in our opinion. We are just starting the process of replacing the clamps on the Tug. Some of the factory clamps are showing signs of rust, something I've never seen with AWAB. Also, the AWAB do not have cut holes for the wormdrive, so are better for the hoses. If you go that route, it is worth getting their clamp tool - it is a flexible shaft driver that fits the nuts, which I think are metric.

Finally, Practical Sailor is going to have a clamp comparison in the upcoming issue, which should be in my mailbox any day. I'll be interested to see what they recommend.

NAPA. They have a number of different stainless steel hose clamps, to include "constant torque"..... I've had good results with their clamps.

If I'm planning a project, I get them from defender.com. I buy the best quality they offer. If I need a few right away, I just ride down to West Marine. Again, I buy the best quality they offer.

No auto parts store clamps for me.

With many of these products a better source might be the marine supply that services the local boat yards.

Purchasing in box rather than single quantities can reduce many prices by 50%.

A Dozen hose clamps of the same size get used quickly.

I have used lots of clamps bought at ACE Hardware. They hold up well for me.

Good clamps are one of the best investments you can make on a boat. Mine was full of auto store type clamps, and there are a few fittings below the waterline that have insufficient length for twin clamps, so they gotta be good. I've been buying mine from Hopcar these last couple of years and selling the cheap take-offs at automotive swap meets.

If you're not buying "marine" hose clamps, the screw part may not be actual stainless steel. Also, the best clamps are the one that are smooth on the inside with no perforations.

Considering that in some cases a failed hose clamp could sink your boat, this is not the place to go cheap.

Avoid cheap or non-marine clamps - the screw part can rust and fall off some of the cheaper clamps, I've seen some... Basically you then have no clamping at all.

Thanks guys, I want to take a good look at all your suggestions when I have time in the next couple of days.

Good question Shoalwaters. I recently cleaned and refurbed my after coolers using the same hose clamps. I ran the engine for about 30 minutes and noticed a small leak at the hose that connects the aftercooler raw water output to the tranny cooler. I tighten the clamp and stopped the leak. The next week I ran the engine about an hour and after we anchored I did my normal post flight inspection and found that same clamp broken and just hanging on the hose. I also noticed some salt encrusted on the air intake filter located just below the hose. I replaced all the clamps from the aftercooler raw water output to the heat exchanger input. I had some trouble starting the engine but when I did it ran fine and up to the same rpm as before. The next day I ran it at cruise rpm and noted no problems. I believe I got some water intrusion into the engine due to the failed clamped but not much. I hope I blew most of it out running it the next day for an hour, I least I hope so. I will probably change the oil.

This experience is the best reason I can think of to use good quality clamps and change them every so often.

It has to say, "All Stainless" on the clamp for me to use it on my boat.

A little about Clamptite here:
One More Time Around: Water We Doing About Winter?
They're great overall, but don't count on doing one in a confined space or on a moving boat unless you've got it mastered.

As far as perf vs. non-perf -- non-perf preferred, but by the time the perfs would cause me any problems, I'd have already replaced the hose.

Lastly, it's nice to have a single wrench for hose clamps so the tightening hexes should all be the same size.

"ALL" stainless is like "Hi Fi" in days of yore.

Meaningless as there are probably 100 grades of SS.

Not all are suitable for sea water.
