NOS Nitrous Bottle Pressure ''Racer Safety'' Blow-Off Adapter
The NOS "Racer Saftey" devices are designed to fit on the bottle valve. If your nitrous system creates too much pressure due to a rise in ambient temperature or the overuse of a bottle blanket/heater; one of these caps will allow it to bleed off through the vent tube, which must exit outside the vehicle. Both NHRA and IHRA require these blow-off caps when you run with nitrous oxide!
