Need a reliable clamp that can handle vibration and temperature changes?
These Oetiker double ear clamps are a smart choice.

Made from tough stainless steel (material 1.4307/UNS S30403), they've got two ears instead of one, which basically doubles the clamping range and adds a bit of flexibility – perfect if the hose or fitting expands or shakes around.
The ID range is 12.5mm when closed, stretching up to 15mm open.

You get 10 in a pack, so you'll have spares handy.

Installation is a breeze with Oetiker pincers (sold separately) – just pinch the ears until they deform (that's how you know it's tight).
Removing them?

Easy with a clamp cutter.

They've got deburred edges too, so they won't scratch up your hoses.

Quick tip: measure the outer diameter of your hose after it's on the fitting – it should be a bit larger than the clamp's average ID for a snug fit.

Oh, and these aren't for PEX tubing – Oetiker makes special ones for that.
Solid, secure, and simple.
