Sealing connector for liquid and gas systems

Claim 1

A sealing connector for liquid and gas systems comprising: a first member having an end surface defining first and second passageway openings; a second member having an end surface defining third and fourth passageway openings; and first and second resilient o-rings secured to one of said first and second members and surrounding each of the passageway openings of said member, said o-rings projecting outwardly from the end surface of said member; said first member having a shoulder facing away from the end surface, the shoulder having a first portion which is generally semi-cylindrical with a central axis parallel to a line between the first and second openings, the shoulder having a second portion extending further from the central axis than the semi-cylindrical first portion; said second member including a C-shaped arm extending beyond the end surface and defining a cam surface terminating at a point spaced apart from the end surface, the first and second portions of the shoulder of said first member and the cam surface of the arm of said second member being shaped and oriented to provide for connection of said first and second members by placement of the cam surface of the arm of said second member adjacent the first portion of the shoulder of said first member and rotation of said first member relative said second member about an axis parallel to the central axis, the cooperation of the cam surface of the C-shaped arm with the second portion of the shoulder upon rotation resulting in the end surface of said first member being forced against the end surface of said second member with said o-rings being resiliently deformed therebetween to provide a sealing relationship.
