Abstract
An attachment system (601) for maintaining a passageway (603) of a tube (605) in axial alignment with a passageway (607) through a housing (609) includes a spring (611) having an exterior edge (613) and an interior area (615) passing the tube (605). The housing (609) has an exterior mating surface (404) around the passageway (607). A mating end (402) of the tube (605) abuts against the mating surface (404). A spring retainer (617) apart from mating surface (404) restrains the movement of the spring (611) away from the mating surface (404). A tubular coupler (619) in proximity to the mating end (402) restricts the movement of the mating end (402) toward the interior area (615) of the spring (605).
