    • A composite drain plug comprising a metal plug element and an elastomeric seal element. The plug element includes a body with a head portion defined in part by exterior, tool-engaging flank surfaces, a radially enlarged, seal positioning flange with an outer diameter surface and a seal-engaging end face surface. The plug also includes a threaded fastening shank, and a depth stop shoulder with a radial end face surface and an axial offsetting surface. The elastomeric seal element includes a seal body integrally bonded to the positioning flange and to offsetting shoulder surface on said depth stop. The seal body also includes a radially extending, axially inwardly directed end face primary sealing surface, lying axially inwardly of the end face of the depth stop.
    • 一种复合排水塞,其包括金属塞元件和弹性体密封元件。 插头元件包括主体,该主体部分由外部限定,工具接合侧面,径向扩大的具有外径表面和密封接合端面表面的密封定位凸缘。 插头还包括螺纹紧固柄和具有径向端面表面和轴向偏移表面的深度止动肩部。 弹性体密封元件包括一体地结合到定位凸缘上的密封体,并且在所述深度止挡件上抵靠肩部表面。 密封体还包括径向延伸的,轴向向内定向的端面主要密封表面,位于深度止动件的端面的轴向内侧。

    • An oil seal unit for disposition between mating parts having opposed end face sealing surfaces. The seal unit has a casing with a radial flange having opposed end face surfaces and an inner margin portion. An elastomeric seal body with radially inner, outer and intermediate body portions is bonded to the casing. The seal body includes a radially space apart, continuous circular sealing ribs over lying each face of the casing; the seal body also has a radially inner portion defining an opening through which the shank portion of the mating part extends. The intermediate part of the seal body includes a collar element which deforms into snug fluid-tight sealing engagement within a recess defined in part by the seal and in part by portions of the mating parts.
    • 一种油封单元,用于配置具有相对的端面密封表面的配合部件之间。 密封单元具有具有径向凸缘的壳体,该径向凸缘具有相对的端面表面和内边缘部分。 具有径向内,外和中间体部分的弹性体密封体结合到壳体。 密封体包括在壳体的每个表面上的径向间隔开的连续的圆形密封肋; 密封体还具有限定开口的径向内部,该配合部的柄部延伸穿过该开口。 密封体的中间部分包括一个套环元件,该套环元件在部分由密封件和部分由配合部件的一部分限定的凹部内变形成紧密的流体密封密封接合。
