ABSTRACT:
A fluid manifold defining a body has a surface defining a plane. A bore extends into the body from the surface and defines a seat. The bore is adapted to receive a tube nut into a seated position against the seat. A first tube nut and a second tube nut having respective bodies with first and second lengths and first and second flanges positioned at one end of each body are provided. A tube nut stop is disposed adjacent the bore and is sized to engage the flange of the first tube nut when placed into the manifold at the bore, thereby preventing the first tube nut from being seated against the seat. The tube nut stop is of insufficient size to engage the flange of the second tube nut when seated against the seat in the bore, thereby allowing the second tube nut to be seated against the seat.
