Abstract:
A number of variations may include a product comprising: a bushing (100) located at a cavity (56) formed by a stationary body (46) of a valve (12), and located around a movable stem (48) of the valve (12), wherein the bushing (100) facilitates movement of the stem (48); and a seal member (102, 104) located in the cavity (46), around the stem (48), and on the inboard side of the bushing (100), wherein the seal member (102, 104) substantially prevents fluid-flow between an outer diametrical surface (76) of the stem (48) and a confronting inner diametrical surface (120, 128) of the seal member (102, 104), forming a first seal.
