DAS compact seals are a double-acting sealing and guiding component consisting of an elastomeric sealing ring, two backup rings, and two guide rings. The das piston seal provides excellent sealing performance in both static and dynamic conditions, while the backup rings prevent extrusion of the rubber sealing ring.
DAS 紧凑型密封件是一种双作用密封和导向部件，由一个弹性密封环、两个支撑环和两个导向环组成。DAS活塞密封件在静态和动态条件下均具有出色的密封性能，而支撑环可防止橡胶密封环被挤出。
设计说明：
导向环可作为有效的支撑元件，弹性元件的独特结构设计可确保在沟槽内无变形安装。DAS 密封件液压是密封和导向的紧凑组合，适合安装在开放式或封闭式沟槽中，可在极其狭窄的空间内应用。
Materials:
密封圈：丁腈橡胶（NBR）
支撑环：高强度聚酯弹性体
导环：改性聚甲醛 (POM)
