Abstract
A cylindrical thin walled tube with a through bore extending its entire axial length between first and second opposed ends is individually mounted in a bore in a fitting, with an end portion of the tube extending outward from a land surface on the fitting. A groove is formed on the exterior of the tube between the first and second ends and receives a seal element which is engageable with the land surface on the fitting. At least one mounting barb is formed on the body, generally adjacent one of the ends of the body, for fixedly mounting the tube in the bore in the fitting. The tube may also be formed with multiple mounting barbs and multiple grooves, each groove receiving a separate seal element. The outwardly extending portion of the tube acts as a male pilot for guiding the precise alignment of a bore in a complimentary fitting into alignment with the bore in the fitting in which the tube is mounted.
