An improved seal for sealing a shaft in a stuffing box is characterized by a pair of annular seal elements positionable coaxially end to end around the shaft in the stuffing box. One of the elements is sealed and fixed around its inner periphery with the shaft, and the other is sealed and fixed around its outer periphery with the stuffing box. Abutting ends of the seal elements have complimentary configurations, and are movable together into closely mating, sealed and slidable engagement. Thus, upon relative rotation of the shaft and stuffing box the one element is stationary relative to the shaft and the other relative to the stuffing box, the abutting ends of the elements slide across each other in sealed engagement, and the elements seal the shaft in the stuffing box.

Mechanical-dynamic rotary seal

A three dimensional corner fixture for a flexible joint or the like is prepared from a continuous belt or strip of flexible flat material. The strip is partially slitted from an edge, and an insert is secured between the opposed edges of the slit to allow the material to substantially conform to the shape of a flanged corner, preferably with a leg or tab extending from the insert and secured at least through the radius at the corner.
