【HEXA TIMES】No.4 Since 1970, Rokuriko Rubber has been supplying special O-rings used in cylinder liners for marine diesel engines. When using rubber for gaskets and O-rings, the compression set is a very important characteristic, as a large strain rate can compromise sealing performance. The material MF2702 (fluoro rubber), produced with a special formulation, achieves excellent heat resistance and low compression set, contributing to the longevity of diesel engines. Regarding compression set characteristics, MF2702 has a remarkably excellent property of 4%, compared to the standard value of 40% specified in the old JIS B2401 Type D (heat-resistant O-rings).
