Abstract

A pressure relief seal for pressure tanks having separable tank sections is disclosed. The seal is formed by an O-ring within an O-ring cavity, in turn formed by each tank section. Overpressurization or improper assembly of the tank sections causes the O-ring to be displaced from its sealing position to permit fluid in the tank to flow past the O-ring and through pressure relief channels at the seal.
