Edelbrock 72901 - Edelbrock Nitrous Bottle Pressure Safety Blow-Off Adapter

CNC-machined Racer Safety Blow-Off Adapter replaces the standard safety valve to allow for the use of a hard line blow-down tube like the Edelbrock Nitrous Blow-Down Tube. #72901 is a direct replacement for the safety valves that come with all Edelbrock nitrous bottles (5-lb. and larger). A blow-down tube is an essential safety feature for hatchbacks or cars with the bottle mounted in the passenger compartment.
