1、因根部磨损而漏油
根部磨损的主要原因是预压缩量太大。因此需注意密封圈的内外径尺寸与密封沟槽尺寸，要合理选择密封圈的内外径与油孔径及密封沟槽尺寸，并注意它们的配合。
2、因尘埃损坏而漏油
液压油中的污物及从活塞杆进入液压缸内的污物等，往往会使Y形密封圈产生异常磨损，因此除注意保持液压油的清洁度外，应在活塞杆外伸端设置防尘圈。
3、因偏磨而漏油
当密封圈受偏心负载作用时，在负载集中的位置产生大的磨损，而其余位置磨损很小或不磨损。磨损不是发生在唇部的整圆上，加偏磨。
产生偏磨的原因有：a.承受偏心负载(例如水平放置的大型合模缸，因活塞重力下垂形成偏心负载);b.密封沟槽加工偏心;c.配合间隙过大，导致压缩余量不均匀(如液压缸此时易出现活塞与活塞杆的轴心线与安装的密封圈中心线不同心);d.液压缸装配不好。
4、因裂纹而漏油
Y形密封圈的某些严酷条件下使用时，可能出现裂纹。例如在高温高压下使用的Y形圈常产生这种现象，裂纹导致密封失效而漏油。
可以通过选择适当的材质，并采用夹布橡胶Y形圈来解决。另外Y形唇部不容易开裂。
5、装配不好切破密封，导致漏油
将装好Y形圈的活塞往缸体内插入时，如果未用引导工具，则会因唇部存在压缩余量，而缸体孔口又不便于倒角，则活塞推入时困难。因得用起子撬着强行推入，这会造成密封唇部翻转而拉裂，造成漏油。所以一定要采用后述所示的剖分式带锥面的引导工具装入Y形密封圈。且在安装时，要谨防带入铁屑尘埃等污物，以免拉伤Y形圈而漏油。
6、Y形圈在压力超过20MPa时，要使用挡圈，以防挤入间隙被切掉而产生漏油。
7、密封件的材质与液压油不相容。
