ABSTRACT:
A coupling having an internal pressure-loaded V-seal between a male member and a female member incudes a sleeve member insertable into the female member bore. The V-seal is repeatably positionable in the sleeve member such that insertion of the male member serves to slightly compress the V-seal and thereby preload the seal before pressurization. Upon pressurization of the coupling, the lips of the V-seal are urged to expand longitudinally against the leading face of the male member and an internal shoulder in the sleeve member. The pressurization of the coupling also tends to urge the sleeve member toward the male member, to enhance the seal and to compensate for any tolerances between the coupling halves.
