1. A manifold system comprising:

  • a pipe section comprising a plurality of threaded manifold fittings; and

    at least one coupling, each of the at least one coupling having a centerline and defining a fluid flow passageway, wherein each of the at least one coupling comprises;

    a base member shaped to define;

    a base member distal end comprising base member threads;

    a base member proximal end;

    a shank intermediate the base member distal end and the base member proximal end; and

    a flange intermediate the base member distal end and the shank, the flange having a greater exterior dimension than the shank, wherein the flange comprises;

    a flange proximal surface;

    a flange distal surface, the flange proximal surface being intermediate the shank and the flange distal surface, the flange distal surface being intermediate the flange proximal surface and the base member distal end; and

    a first locking extension that protrudes from the flange proximal surface; and

    a grip member shaped to define;

    a bore sized to receive the shank such that the grip member is slidable axially along the shank of the base member between a locked configuration in which rotation of the grip member about the centerline induces rotation of the base member about the centerline, and an unlocked configuration in which the grip member is rotatable about the centerline independently of the rotation of the base member;

    a grip member proximal end comprising grip member threads configured to engage one of the plurality of threaded manifold fittings; and

    a grip member distal end comprising a grip member distal surface, the grip member distal end being disposed intermediate a grip member proximal end and the flange proximal surface when the shank is received within the bore, wherein the grip member distal surface is shaped to define a first recess that receives the first locking extension in the locked configuration, and not in the unlocked configuration.
