Oetiker Stepless Clamps for Kegerator Gas and Beer Lines

I use stainless steel Oetiker Stepless clamps for most gas and beer applications.  I like the fact that they are… stainless steel, stepless (keep reading) and the fact that they stay tight and will not loosen over time.  These clamps are designed so that there are no steps (gaps) on the inside.  That reduces the possibility that tubing will be torn or damaged.  These are single use clamps.  The upside of that is… Oetiker Stepless clamps will not loosen over time.  When they’re tight, they’re tight.  I really like that for kegerator applications because… A: I don’t like to empty CO2 tanks for no good reason and B: I don’t like standing beer in my kegerator.

A sizing note – Oetiker Stepless clamp sizes generally refer to the largest diameter in mm.  So a size 13.3 means that the Oetiker Stepless clamp is 13.3 millimeters (about .52″) in diameter uncrimped.

Some sizes to consider…

I use a pair of nail nippers (meant for cutting heads off nails) but there are also purpose made tools for clamping Oetiker Stepless clamps…

      It depends on what your outside diameter is. I would go a little bit larger than your OD. If you’re cutting it close on clamp side vs OD, I would put whatever barbed fitting you’re going to use in the tubing and measure to make sure you’re getting the right size.

    These are fantastic, but how do you remove them if needed. I have always had issues undoing the clamps should I need to for any reason.

      I take my nippers and get under the flap of metal and then peel it back. It’s a little hard to begin with but once you get it moving that flap will peel back pretty easily and relieve pressure from the clamp. I should take a picture of that process.

      The way I’ve always done it is to use my crimp tool to cut through the part of the clamp you crimped previously. This is amazingly difficult to explain, but once you cut across the crimped part the clamp splits apart and allows for easy removal.
