ABSTRACT:
The step of soldering, brazing, or welding a tube joint may be eliminated in a tube joint construction that includes a male tube member (10) having a first cylindrical section (14) of relatively lesser diameter and an adjacent, second cylindrical section (18) of relatively larger diameter. Also included is a female joint element (12) having an internal passage (30) which includes an emerging cylindrical section (32) of a diameter just less than the relatively larger diameter and an adjacent, interior cylindrical section (34) of a diameter just less than the relatively lesser diameter. The male tube member (10) is interference fitted into the female joint element (12) to provide a sealed joint without the need for soldering, brazing, or welding.
