A self aligning coupling system for aligning one end of tubing to another end of tubing is disclosed. The self aligning coupling system can include a first coupling member which is engageable with a second coupling member, each coupling member being generally cylindrical and having a flange projecting axially from a first segment of a circumference thereof and a flange-free portion defined by a remainder of the circumference. The first and second coupling members are configured so that when the first coupling member is engaged with the second coupling member, the flange of the first coupling member contacts the flange-free portion of the second coupling member and the flange of the second coupling member contacts the flange-free portion of the first coupling member.
