Nitrous Bottle Mounting
The nitrous oxide storage cylinder is typically called a “nitrous bottle”. The “bottle” is not unlike a scuba
tank. It is an aluminum cylinder, designed and manufactured to withstand very high pressures. The
valve on top of the bottle is a high-flow design that allows easy opening and close which controls the
nitrous flow to the engine compartment.
Accurate calibration of your nitrous system depends on the bottle remaining at a stable temperature. In
vehicles (such as Corvettes) where the bottle must be mounted in an area subject to direct sunlight, it is
suggested that the bottle be shielded with a bottle blanket.
If the bottle is mounted inside the passenger compartment or in a space that has access to the
passenger compartment such as hatchbacks or vehicles that feature fold down rear seats, the
pressure relief device (PRD valve) must be vented externally from the cockpit. This procedure will
prevent the passenger compartment from filling with a cloud of nitrous oxide, should the safety pressure
relief valve rupture.
Special consideration should be made to protect the bottle installation by not placing the bottle
in a known crumple or crash zone within the vehicle. At no time should the bottle be mounted
within the seating area of the passenger compartment of a street-driven vehicle.
Bottle Safety Information
1. Do not attempt to remove the bottle valve. Please return your bottle to Edelbrock if service
is required to the siphon tube inside the bottle or the bottle valve itself.
2. Never heat the outside of your nitrous bottle with an open flame such as a torch.
3. Do not strike the surface of your nitrous bottle with a heavy or sharp object.
4. Do not drop your nitrous bottle.
5. Do not attempt to grind off or destroy any imprinted markings on the face of the
bottle.
6. Do not remove, modify or otherwise tamper with the safety valve on the bottle valve.
Racing Vehicles
Before using the Edelbrock bottle mounting brackets to mount a nitrous bottle in a vehicle intended for
use in racing or sanctioned events, check with the sanctioning association or local race track for any
rules regarding bottle installation. Most associations require the bottle be mounted within the confines of
the safety roll cage, with the safety pressure relief cap vented away from the driver’s compartment.

Bottle Valve Handle Pictured
The Performer RPM Bottle Valve installed on all the bottle
valves used in Edelbrock Nitrous Systems is a Pressure Relief
Device or “PRD”. It is a safety valve designed to vent the con-
tents of the bottle into the atmosphere in case of a catastrophic
event, such as a collision.
It also serves to prevent the over-pressurization of the bottle
itself. Over pressurization can result from over-filling, exposure
to direct sunlight, or high-temperatures. It can also come from a
violent strike to the bottle surface.
It is illegal to tamper with, modify, or remove the PRD device.
