The optimum customer solution Connected. Integrated. Systematic. When the coffee tastes delicious every morning, when your car steers with ease, when the harvest is collected reliably, and when everything goes according to plan in the operating room: be assured Oetiker connecting technology played a part in it. Who invented it? Hans Oetiker. In 1943, he invented the first ear clamp – a global innovation which is still an integral part of the Oetiker product range. But the ear clamp was only the beginning. Step by step, new product lines and services were added. Today, we continue to be...

Unique quality for your connections. Connections that keep their promises When it comes to our customers’ requirements, we take care of every detail, just as with our own products, because we know your high quality connections must be reliable every time. During product development, material selection, processing, and the final quality control, we pay meticulous attention to every minuscule detail. This is why Oetiker connecting solutions are sturdy and resilient – and leakages are a thing of the past. To ensure that each assembly keeps its promise, we also produce premium-quality closing...

To ensure everything runs smoothly: Dimensions, identification and ordering Oetiker Clamps and Rings are manufactured to metric dimensions. For identification purposes, the nominal diameter is stamped on each product. Always quote the 8-digit item number when ordering. You’ll find them on the catalog pages. To determine the correct clamp diameter, push the hose onto the attaching material, (e.g. the nipple), and then measure the hose’s outer diameter. Select a clamp whose average value of the diameter range is slightly greater than the hose’s outer diameter. Tolerance compensation through...
