A split sealing member for a rotary shaft comprising a coiled body, with non-adjoined ends, having a plurality of turns about a central axis, bent along the course of the body such that the body is divided into a radially-inner portion and a radially-outer portion wherein the radially-inner portion defines a first plane and the radially-outer portion defines a second plane which is substantially transverse to the central axis.

Split sealing element

A packing (10) for a stuffing box (12), for example, for petrochemical and/or power industry valves including one or more low density, graphite preform rings (30 and 44) which are further compressed, when the packing gland is tightened, with controlled material flow into the remaining open areas to provide impervious and effective I.D. and O.D. seals. The preform rings (30 and 44) are preferably adjacent higher density graphite adapter rings (32 and 46) with the adjacent facing surfaces (34-36 and 40-42) of the preform and adapter rings, preferably, having acute angles of 45.degree. and 60.degree., respectively, with respect to the axis of the packing.

Stuffing box packing system and method

A Pitman shaft boot seal designed for a static sealing application with one sealing surface compressed against the Pitman arm and the other sealing surface compressed against the steering gear housing. The sealing surfaces are held in place by a compression spring located inside the boot seal. The cylindrical portion of the boot seal is formed with a plurality of identical, equally spaced-apart, parallel, hollow ribs parallel to the axis of the Pitman shaft and extending around the entire circumference of the seal. The ribs allow the boot seal to twist as the Pitman arm moves arcuately, without breaking the static seal at the sealing surfaces.
