Not as convenient because they have to be cut, zip ties also work on silicone and barbed connections.

They can be reopened and reused.

Grab the top part (see arrow) with a pliers and twist it. The two sections will slide apart sideways. If it's on something sturdy, like a large/thick hose, you can do it with just the pliers. If it's on something smaller, you might need to grab the other part of the clamp with a second pliers to hold it still.

No, i meant the zip ties weren't as convenient. Your clip is very convenient, but not everyone has them, and zip ties are pennies.

Stainless steel will absolutely rust in a marine environment.

A4 stainless (type 316) is the most corrosion resistant. A slight surface discoloration is the worst you'd get in a marine environment.

The problem is knowing whether you are actually getting A4/316 stainless so I wouldn't risk it in the aquarium.

Mine did

I live on the beach and I own a carpentry business. There is decks that our company built 20+ years ago with stainless steel screws and not a single one rusted yet.

Stainless steel won’t rust

Yes it will, it just takes longer

yeah about 30 years or so. I would just change the bracket every other year or so

Then what happens to my stainless steal clamp. It has rusted in 4 months

You can use Titanium Clamps. I just use a zip tie.

Ziptie installed with a Panduit gun will do the trick.

All products that say stainless aren’t equal… there are different grades. SS itself isn’t rust proof forever. But I can say that I have personally seen SS decking screws and trim screws last 20+ years in the salt environment…. Back the screw out and toss it back in the bucket it looks like new

Yeah, we get it. You use industry standard materials for your beach carpentry business.

You're comparing apples and elephants. Clamps that aren't supposed to be exposed to corrosive environments are a world apart from something specifically made for outside/marine use.

Not sure why we are debating a clamp…. And FYI there is marine grade clamps. https://www.plumbingsupply.com/clamps.html
