Patent abstract
Provided is a system and method for securing a seal between a thermoplastic liner and a metal boss for a composite cylinder. A metal boss can be integrated with a thermoplastic liner during a molding process. A bushing can be inserted into the metal boss and coupled thereto via threading. The bushing can further include a relief space region having a sidewall that is deformed from a first position to a second position in order to decrease a distance of the metal boss to the sidewall of the bushing, wherein the decrease provides a seal between the metal boss and the thermoplastic liner.
