DZ 型密封为混合式活塞杆密封（图 1），将 NBR 主密封和 LUBRITHANE (TPU) 辅助密封组合到了一个密封中。这种组合可以提供良好的低温回弹性，适用于压力达到 400 bar (5800 psi) 的中载到重载应用。DZ 型密封提供公制尺寸和英制尺寸 。根据客户要求，还可以提供带有弹性体 (FLUOROTREL/TPC) 辅助密封的设计。
带一级和二级密封的活塞杆密封
这种活塞杆密封包括一个丁腈橡胶主密封和一个 LUBRITHANE 热塑性聚氨酯辅助密封。 丁腈橡胶主密封唇可改善长期的密封性能，并具有更强的能力来承受活塞杆和缸头之间较大的径向偏差。
- 卓越的低温和低压密封性能
- 能承受高达400 bar (5 800 psi)压力
- 卓越的活塞杆径向偏差的随动能力
- 可提供公制和英制尺寸
