ABSTRACT:
A universal-type coupling member including a head portion, a stem portion rotatable in the head portion, and a gasket inset in the head portion and in sealable contact with the stem portion, and having a fluid passageway therethrough is provided, which can be connected to another appropriate universal-type coupling member. Use of the coupling member of this invention can relieve the uncoupling effects of twist or torque in universal-type coupling combinations.
