    • A mack washer includes an internal surface with a helical seal that engages the threads on a pop-up body, and a beveled extension depending from the bottom surface. The helical seal follows the shape of the threads on the pop-up body and assumes the shape of the threads, extending generally to the minor diameter of the threads, thereby eliminating seepage. The helical seal can be interrupted to facilitate engagement. A lock nut for use with the mack washer includes a beveled seat configured to engage the beveled extension and urge the beveled extension into further contact with the pop-up body, thereby increasing the sealing effect of the mack washer.
    • 麦克垫圈包括具有螺旋形密封件的内表面,其接合弹出体上的螺纹,以及从底面垂直的斜面延伸部。 螺旋形密封件遵循弹簧体上的螺纹的形状,并呈现螺纹的形状,大体上延伸到螺纹的较小直径,从而消除了渗漏。 可以中断螺旋形密封以便于接合。 与麦克垫圈一起使用的锁紧螺母包括一个斜面座,其配置成接合该倾斜的延伸部并且将该斜面延伸部推动成与该弹出体进一步接触,从而增加了该麦克垫圈的密封效果。
