Abstract:
A chemical injection line connector includes first and second couplings configured to automatically seal shut when the members are disengaged. A method for blocking contamination or pressure transfer of chemical injection lines includes securing first and second couplings to corresponding ends of a chemical injection line and automatically sealing the couplings shut when the couplings are disengaged.
