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)

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

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.

Great product. I am restoring a 76 Triumph TR6 and was having trouble sealing fuel and vacuum lines. I found it was due to dimensional differences between new and original hoses. I bought these clamps and they work perfectly. The original clips we were sized to fit original hose diameter. These look great and dont rust!

Very good quality.

Using these with my home brew setup, easy to install, secure, great product.

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.

they work as they should

These clamps are the best for sealing tube to fittings. Not a single connection leaked.

Five star
