ABSTRACT:
A tube interface (53) includes a first tube (28) and a second tube (34). The first tube (28) has an oblong opening (54) exhibiting a first major dimension (58), and the second tube (34) has an oblong end (52) exhibiting a second major dimension (72). The oblong end (52) of the second tube (34) is inserted into the oblong opening (54) so that the second major dimension (72) is aligned with the first major dimension (58). The second tube (34) is turned in the oblong opening (54) to move the second major dimension (72) out of alignment with the first major dimension (58) of the oblong opening (54) to secure the second tube (34) to the first tube (28) prior to brazing.
