SEALS AND METHODS OF MAKING AND USING THE SAME

A seal, the seal comprising: an annular jacket comprising a body comprising a first lip and a second lip defining an annular recess; a circumferential spring disposed within the annular recess adjacent to one of the first lip and the second lip; and a floating circumferential insert, wherein a radial biasing force on the first lip is decoupled from a radial biasing force on the second lip. 一种密封件，该密封件包括：环形夹套，该环形夹套包括主体，该主体包括限定环形凹部的第一唇缘和第二唇缘；周向弹簧，该周向弹簧邻近于该第一唇缘和该第二唇缘中的一者设置在该环形凹部内；和浮动周向插入件，其中该第一唇缘上的径向偏置力与该第二唇缘上的径向偏置力解耦。
