Abstract:
1. A system, comprising: a chemical injection connector configured to couple chemical injection lines in a mineral extraction system, the connector comprising: a first coupling configured to be secured to a first chemical injection line, wherein the first coupling comprises a first valve in a first fluid pathway; and a second coupling configured to be secured to a second chemical injection line, wherein the second coupling comprises a second valve in a second fluid pathway; wherein the chemical injection connector is configured to selectively open and close only one path of flow through the first and second couplings, wherein the first and second valves are automatically biased toward respective closed positions resisting ingress of an external fluid when the first coupling is not mated to the second coupling, wherein the first and second valves are automatically biased toward respective open positions when the first coupling is mated to the second coupling.
