Abstract: A packing assembly adapted to be mounted on and seal a reciprocating shaft includes a packing nut, an elastomeric sealing member releasably coupled to the packing nut, and a keeper to facilitate the releasable coupling between the elastomeric sealing member and the packing nut, wherein the entire assembly is removable from the reciprocating shaft as a unit.

Abstract: A dynamic seal assembly for a rotating member comprising a first split housing carrying a first split seal, a second split housing carrying at least one second split seal, each split seal being resiliently closed so that sealing contact is maintained when the rotating member wobbles. The free ends of the second split seal overlap with one another in either a side-by-side relationship or an over-under relationship, or both.

Abstract: Split packing followers for use with valves are disclosed. A disclosed packing follower includes a first member having a first portion of a flange and a first portion of a curved wall extending substantially perpendiculary from the first portion of the flange to define a first portion of a cylindrical member. The disclosed packing follower further includes a second member separable from the first member. The second member include a second portion of the flange and a second portion of a curved wall extending substantially perpendiculary from the second portion of the flange to define a second portion of the cylindrical member. The first and second member include complementary interlocking structures that are configured to mechanically couple the first and second members to form the packing follower.
