Nitrous Oxide Systems 16169NOS Safety Blow Down Adapter

Any IHRA or NHRA-sanctioned track will require these blow-off caps in all classes when you run with nitrous oxide. These are safety devices that fit on the bottle. If your nitrous system creates too much pressure, one of these caps will allow it to bleed off through the vent tube, which exits outside the vehicle.

Adapter Fitting Included: Yes
Fitting Size 1: -8 AN
Quantity: Sold individually.
Notes: Designed to fit 2nd generation Hi-Flo/Super Hi-Flo valves.
