Stainless Steel Oetiker Style Clamps AKA Stepless Ear Clamps

Stepless ear clamps are the best clamp for attaching hoses. The entire inner circumference of the clamp is completely free of any steps, gaps or bridges for no-leak seals. It requires the use of a special tool (Oetiker Clamp Tool).

Need to know what size you should use for standard draft beverage lines? 
13.3 is typically used for attaching 3/16" beer line when the barbed fitting is 1/4". 
14.5 is typically used for attaching 1/4" lines
15.7 is typically used for attaching 5/16" gas lines when the barbed fitting is 5/16".
17.0 is typically used for attaching 5/16" gas lines when the barbed fitting is 3/8".

In many cases, regulators and air distributors come with a 3/8" barb on the shutoff. In this case, a 17.0 would need to be used.

Below is a helpful Oetiker Clamp Sizing Chart to help determine the right size stepless clamp that you might need.

Simply measure the outside diameter of the hose installed on fitting.  Then select a hose clamp so that the outside diameter of the hose is approximately in the middle of the clamping range of the clamp.

How are the stepless clamps sized?

The size listed for each clamp is the maximum inner diameter in mm (millimeters) before being crimped. Refer to the chart above to find the approximate size of the clamp after being fully crimped.
