A sealing unit capable of sealing engagement with an end of a tube. The tube has an outer wall and a bore surrounded by an inner wall. The seal unit comprises a tapered element having a longitudinal axis. The tapered element is adapted for insertion into the bore in the end of the tube. A sealing ring co-axial with said longitudinal axis of the tapered element to provide an annular channel between the tapered element and the sealing ring. The annular channel has an open end and a closed end. The annular channel is capable of receiving the end of the tube through the open end of the annular channel. A base, co-axial with the longitudinal axis of said tapered element, contacts the sealing ring to hold the sealing ring in place and contacts the tapered element to terminate the annular channel at the closed end. When the sealing unit is in sealing engagement with the end of the tube, the tapered element sealably engages the inner wall of the tube and the sealing ring sealably engages the outer wall of the tube.

An apparatus is provided for forming a tubular fitting from a blank tube having an interior. The apparatus includes a right die plate, a left die plate, a lower die plate and an upper die plate. The right die plate has a first cavity capable of receiving the blank tube. The left die plate has a second cavity aligned with the first cavity. The right die plate has a first guide post and the left die plate has a second guide post. The first cavity is joined to the second cavity to form a forming cavity. The lower die plate is capable of supporting the right die plate and the left die plate. The lower die plate includes a port capable of receiving a fluid line. The upper die plate is capable of moving between a first position and a second position. The upper die plate has guide holes for receiving the first and second guide posts and aligning the upper die plate with the right die plate and the left die plate. The apparatus further includes a fluid delivery means for communicating a fluid via the fluid line to the interior of the blank tube.

A apparatus and method for forming a complex-shaped frame member from a blank tube having opposed ends is provided. The blank tube is placed in a first cavity on a lower die. An upper die is lowered from an open position to a close proximity to the lower die. The upper die has a second cavity aligned with the first cavity. A pair of sealing units seal the opposing ends of the blank tube, and a fluid delivery means for communicates a fluid into the tube. A fluid control means pressurizes the fluid in the tube to a low pressure level. A position determining means determines a distance separating the upper die in the closed position from said lower die in the lowered position. A lower die lifting means raises the lower die from the lowered position the determined distance to the lifted position. The fluid control means then pressurizes the fluid in the tube to expand the tube to conform to the forming cavity.
