A heat exchanger of the tube-fin type comprising a tank (10) having first (14) and second (16) ends, a plurality of tubes (34), a plurality of baffles (38) and a plurality of fins (42). A cap (50, 52) is connected to each end (14, 16) of the tank (10) and includes a fluid coupler (60, 61). Each cap (50, 52) comprises a female member (74) disposed therein including a plurality of interior passageways (88), first (90) and second (92) annular channels intersecting with opposite ends of the passageways (88), and a plurality of islands (94) bounded by the passageways (88) and first (90) and second (92) channels. The tank (10) further comprises a male member (72) extending from each end (14, 16) and including a plurality of outwardly extending tabs (76), an annular extending rim (82), and an annular resilient seal (84). A cap (50, 52 ) is disposed about each end (14, 16) of the tank (10) by inserting the tabs (76) into the longitudinal passageways (88) and extending the cap (50, 52) about the tank (10) until the tabs (76) intersect with the second channel (92) and rotated block the cap (50, 52) and the tank end (14, 16) together.
