Innovative designs are becoming smaller and smaller, and as a result, the market demand for miniature components is growing. Hence, our team has accepted the challenge to develop the world's smallest o-ring! We specialize in extremely tiny o-rings and custom
KEF succeeds in manufacturing a "flash free" and "no parting Line" O-ring. We develop products, where there can be no debris, e.g. for medical, where mold part lines and burrs have become problems. Functionally, this will provide your products superior
This requires strict industry standards and that each part will meet or exceed those standards, time after time. Making material with high precision and high reliability is a critical issue. It is also critical in our O-rings.
This was no easy task. Diaphragm thickness and diameter are 0.025"±0.004 and 2.840" respectively with nylon cloth inside. The three-layer structure is created by compression molding on both sides of a nylon cloth with special rubber that we have developed.
Accuracy and reliability are important for use in space. This watch seal's specifications are waterproof up to 1000 meter deep and must withstand temperatures of -20°C~+70°C. A product is developed using our newest raw material compound, proving high quality and
