An improved reemployable tubular connection system and method for oil field application disposes an axially asymmetric seal in a coupling sleeve interconnecting the oppositely entered pin ends of two tubing sections. The sleeve includes an approximately central interior surface for seating a deformable seal having oppositely directed tapered edges with different angles of convergence. The pin ends enter into and resiliently displace the edges of the seal, which may be made differentially adhesive so that a tubing connection may be broken and remade a number of times.
