Abstract
This invention is a seal assembly for sealing fluid needles, spindles and other movable cylindrical objects where a fluid tight seal is needed between the fluid and non-fluid sides of the movable cylindrical object. The seal includes a packing member with a sharply cut-off tubular end and a stop member with a conical recess, both of which encircle the movable cylindrical object. An unrestrained flow cavity is defined by the packing member and the stop member. Positioned behind the packing member are a spring and washer which axially bias the packing member into the conical recess.
