Abstract: An improved fluid conduit union and method for hammerless attachment apparatus for hammerless coupling the ends of abutting fluid conduits, such as pipe, hoses, or attachment fitting conduits, comprising a ring-shaped conduit receptacle assembly threadedly engaged and fixed on a female fitting at one conduit end and a cylindrical ring-shaped locking assembly positioned around a male fitting at the other conduit end. The ring-shaped locking assembly has a lock ring positionable by a rotatable locking ring nut threadedly engaging the ring-shaped conduit receptacle. Rotation of the locking ring nut translates the lock ring against the male fitting and firmly seats the male fitting at one conduit end to the female fitting at the other conduit end where they are locked in place, all without rotation of either fluid conduit.
