标准材料：
密封环:填充聚四氟乙烯F-PTFE
0形圈:丁腈橡胶NBR或氟橡胶FKM
特点：
•良好的动静密封性能
•可允许较大的挤出间隙，视应用场合而定，故可降低加工费用
•由于较大的挤出间隙，在有污物的介质中也可安全使用
•摩擦小，无爬行现象
•沟槽简单，可用于整体式活塞
•由于可采用较多种类的材料，所以对工作条件的适应性强
•若有特殊要求（压力、温度、速度、特殊介质等）， 请与本公司的咨询服务部联系，以便向您推荐合适的材料
应用范围
液压系统、往复运动，在高压和低压及高频工况下的重载双向活塞密封场合非常出色。适用在长及短行程的情况，并在范围较大的流体和高温场合，可适合较大的活塞间隙。例如用在注塑机、推土机、农业机械、压机和其他机床等。符合IS0 7425/1 GB/T1542. 1-94 GB/T15242. 3-94标准。
