ABSTRACT:
A fluid connection comprised of a first fitting having a body with a first end and a second end. A passage extends through the body from the first end to the second end. A bracket is mounted to the second end of the body. The bracket defines a space adjacent the second end. A mounting element is provided for mounting the first end of the body to a fluid inlet line. A piston is movable within the passage. The piston has an inlet side facing the first end of the body and an outlet side facing the second end of the body. Apertures through the piston fluidly connect the inlet side of the piston to the outlet side of the piston. A second fitting, having a fluid opening therethrough, is dimensioned to be slidably received within the space adjacent the second end of the fitting. The piston is movable into engagement with the second fitting with the apertures in the piston communicating with the fluid opening in the second fitting.
