Gauging device and method for coupling threaded, tubular articles and a coupling assembly

摘要

A gauging device and method for use in coupling threaded tubular articles including tubes and couplings. The device and method provides for the use of gauges for the tube and coupling that provide markings thereon that when in register during coupling indicate when a preselected threading distance has been achieved. A coupling assembly is provided that employs an annular gasket attached to the coupling and adapted to be deformed by the end of a tube when inserted into the coupling to provide sealing.
