COG has a huge selection always in stock. In addition, we´ll manufacture lots of things you won´t get elsewhere, on request specially for you. In the shortest possible time. At the fairest of prices. As a one-off order or as a batch.

Customized production of O-Rings

You can't find what you're looking for in our vast range? No problem - COG customised production will be pleased to help with your special requirements. Even the most "unconventional" seals can be individually manufactured at our own production facilities (in-house compounding, in-house development, in-house toolmaking). In the materials and qualities of your choice - within a matter of days. Singly and in large or small batches. It's an offer that few other manufacturers can match. And another thing that you'll be pleased to hear: customised production at COG costs less than you think. Let’s talk about your aims!
