Oetiker 16700010 Stepless Ear Clamp, One Ear, 7 mm Band Width, Clamp ID Range 10.8 mm (Closed) - 13.3 mm (Open) (Pack of 25)

Great clamps for beer lines 1/4 and 3/16, make sure to get some 15.7 Oetiker clamps for your 5/16 CO2 lines. If you are working on your beer and CO2 lines do yourself a favor and buy Oetiker clamps the screw clamps and cheap clamps are not as good and you will have leaks or be replacing.

i clamped the hell out of some fuel line and it hasnt leaked. enough said.

Very good quality.

Great clamps. Must have special tool to install.

These are ideal and well-priced. Very useful, need a special wrench just FYI

great

GREAT PRODUCT & PRICE

Provided one has the correct crimper, this design of clamp is really excellent for permanent connections. Fast and solid. I would not use this clamp if removal is often needed. Great clamp design, faithful manufacturing of the clamp. I especially love the smaller size. This type of clamp is great extra insurance for irrigation hose connections. I have used these clamps for barbed connections, but have not used them to clamp to fittings that do not have a barb or enlarged end. I would not want to use this clamp on fuel lines without checking with the manufacturer.

Exactly what they say they are and a good price. I WILL be buying more.
