聚四氟乙烯 SPGO 密封件是一种低摩擦活塞密封件，由聚四氟乙烯+铜密封环和橡胶 O 形圈组成，用于液压缸的双向活塞密封，以密封流体，从而防止流体流过活塞，使压力积聚在活塞的一侧。.
在建筑行业，SPGO 是液压缸中最常用的聚四氟乙烯组合密封件之一。它具有优异的动态和静态密封效果。.
聚四氟乙烯 SPGO 活塞密封件可用于孔和轴，但密封效果相同。它根据自身的变形，在密封面上产生较高的初始接触应力，以防止液体泄漏。液压缸工作时，压力液体通过 O 形圈的弹性变形，开始最大程度地挤压方形密封圈，使其紧贴密封面，产生较高的附加接触应力，该应力随压力液体压力的增加而增大，并与初始接触应力一起阻止压力液体的泄漏。.
SPGO Piston Seal is used in piston of cylinder, such as pressure equipment, engineering hydraulic machinery, metallurgical machinery, machine tool, Servo hydraulic system and control oil cylinder.
