一、性能与用途
由一个抗磨的填充聚四氟乙烯（PTFE）环和O形橡胶密封圈组成。O形圈提供预紧力，可对PTFE方形环的磨损起补偿作用。适用于液压缸活塞的密封，为双向密封。一般与导向环配套使用。孔径小于40的规格， 应采用分体式沟槽。
二、材 质
PTFE+NBR，特殊情况下橡胶弹性体采用氟胶FKM。
三、工况条件
工作压力：0-40MPa；
往复速度：≤5m/s；
使用温度：O形圈为丁腈胶NBR时：-30～+120℃，氟胶FKM时：-20～+200℃；
工作介质：液压油、气、水（在磷酸酯液压油中选用氟胶）。
四、设计标准
本系列符合ISO 7425/1标准，符合GB/T15242.1-94及GB/T15242.3-94标准，可参照霞板公司GS55044系列，Merkel公司OMK-MR系列及Parker公司OE系列。
五、标注方法
孔用方形圈用订货号来标注（见后面）。
