Classification: CPC B  F | IPC F

Claim 8:
9. A tube assembly, comprising:
a metal pipe portion extending from a first end to a first transition end, the first transition end comprising a first tooth element and a second tooth element disposed circumferentially adjacent to the first tooth element, the first tooth element comprises a first peak, a first valley, and a first transition portion extending axially and circumferentially from the first valley to the first peak, the first peak spaced apart axially from the first valley, the first transition end including a radial transition having a taper in a radial direction;
a polymeric pipe portion having a second transition end, the second transition end having a complementary shape to the first transition end, the second transition end bonded to the first transition end; and
a metal fitting coupled to the first end, the metal fitting configured to couple the tube assembly to an adjacent tube assembly, wherein:
in response to coupling the tube assembly to the adjacent tube assembly via the metal fitting, the metal pipe portion and the polymeric pipe portion are fluidly coupled to the adjacent tube assembly, and
the second transition end bonded to the first transition end by injecting a liquified polymeric material into a mold and allowing the liquified polymeric material to cool, solidify, and form the polymeric pipe portion.
