What is Nitrous Oxide ?
Nitrous Oxide is a cryogenic gas composed of nitrogen and oxygen molecules. It is stored as a “gas over a liquid”
which means that both liquid and gaseous nitrous oxide is delivered into your engine. It is 36% oxygen by weight,
which is what produces the added horsepower. By injecting more oxygen (and a corresponding fuel signal), we
create the additional power much like a supercharger or a turbocharger does.
Nitrous Oxide is considered an “oxidizer” and not a fuel. Nitrous oxide is non-flammable by itself. Because nitrous
oxide is a cryogenic, the same safety methods in handling dry ice apply to nitrous. Direct contact with the skin will
cause a burn similar to contact with dry ice. The exception in using nitrous oxide comes from increased breathing
hazards associated with the gaseous properties of nitrous oxide.
Nitrous Oxide is offered for sale in two common grades, which are U.S.P., and Nytrous Plus. U.S.P. nitrous oxide is
medical grade nitrous oxide. Its common use is dental and veterinary anesthesia as well as use as a propellant in
food such as canned whip cream. U.S.P. is not available to the public and would provide no advantage in the making
of horsepower over the automotive grade nitrous oxide.
Nytrous Plus was specifically designed for automotive consumption and differs from U.S.P. in that it contains trace
amounts of sulfur dioxide (100 parts per million or “PPM”) added to prevent substance abuse. The Sulfur Dioxide is
an irritant to all of your breathing passageways and will cause sore throats and sore nasal passages. Nytrous Plus
was specifically created for automotive applications and is available for sale to the public at many speed shops
across the USA.
þþSafety Steps For Working With Nitrous Oxide
1. Never inhale Nytrous Plus (Nitrous oxide (N2O) for vehicular use) as continued exposure can cause death. Nytrous Plus has a maximum of 100 parts per million (ppm) of sulfur dioxide and will cause irritation to nose
and throat passageways.
2. When working around any high-pressure gas including nitrous oxide, take all precautions to ensure that
exposure to nitrous oxide is minimized.
3. Do not vent nitrous oxide to atmosphere in confined spaces. Only vent nitrous oxide in well- ventilated and
open areas.
4. Liquid nitro us oxide can cause burns to human flesh so protect all skin in and around your hands, arms
and face. Wear safety glasses and rubber gloves to protect from liquid nitrous oxide splatter.
5. When venting down the nitrous system, vent the line down closest to the nitrous bottle.
6. Do not use any form of Teflon tape as sealant on fitting connections. Use only Teflon paste.
7. When washing components, ensure the clean components are completely dry, free of oils, and solvents.
Failure to remove all liquids could cause component or system failure.
8. Always turn the bottle off before making any repairs to the nitrous delivery system.
9. To safely release nitrous oxide in a pressurized line:
a. Position vehicle in a well- ventilated, unconfined space.
b. Turn bottle off.
c. Slowly loosen the nitrous feed line at the bottle until you hear a light hissing noise.
d. Allow the entire nitrous pressure to vent from the line.
e. Perform your work on the system.
f. Tighten the nitrous line to the bottle.
g. Slowly open the nitrous bottle valve, listening for leaks.
h. Perform leak checks on all a ffected fittings and the bottle fitting.

Pump Warnings
1. Always use Teflon pipe sealant on all pipe (NPT) fittings. It is recommended to use a Teflon paste
sealant instead of Teflon tape to ensure no blockages in your system commonly caused by the use of
Teflon tape.
2. Loose connections of both feed air and nitrous oxide can cause serious injury or death.
3. Always pump nitrous oxide through a nitrous filter. Never pump unfiltered nitrous oxide.
4. Do not exceed 100 psi for driving air pressure. Pressures in excess of 100 psi can cause equipment
damage and/or catastrophic failure of equipment. Serious injury or death can result. A high quality
regulator/filter system should be used to assure no damage occur to air-driven pump used in the nitrous
refill station.
5. For the maximum pump life, driving air should be filtered to 10 microns.
6. Always use an inline water separator between air compressor and Refill pump. Failure to do so may
result in shortened pump life, corrosion, and pump failure.
þSafety Tips for the Refill Station
1. Always chain your “mother” bottle securely to a wall or solid work station to protect the bottle from falling.
2. Place the station away from high foot traffic area. This will prevent exposure to residual nitrous oxide
vapors and tripping dangers associated with the “mother” bottle stand.
3. Positively mount the pump to a solid work surface. Do not attempt to fill nitrous bottles without mounting
the pump. The pumping process is cyclical and therefore the pump will vibrate during the pumping process.
This will cause the pump to move and possibly fall over if not mounted properly.
4. The cyclical nature of the pumping process will cause minor whipping of the nitrous feed lines. Take care to
not bind or restrict the movement of the nitrous feed lines.
5. Place your refill station in a well-ventilated area away from any open flame which would included heated
devices such as hot tanks, water heaters and any area in close proximity to such equipment as welders.
6. Always completely remove the bottle that you plan to fill from the vehicle or motorcycle that it is installed.
7. Always verify the cylinder that you are filling has a current hydro test date. The month and date (mm*yy
format) are stamped into the neck of the bottle. Never fill a bottle that is more than five years past its
test date. These bottles should be sent for re-certification. This can be done through most welding or
scuba supply shops for a minimal charge.
8. Never fill a bottle that has been altered, modified, dented, or appears to be heated by a open flame.
9. Always verify that a pressure release device is installed on the bottle valve. It is illegal to fill a bottle in
which the PRD has been removed or modified in any way.
10. Never drive the pump with any gas other than clean dry air or vapor CO2 regulated at no more than 100
psi. Use of 100 psi or more driven air can damage nitrous refill pump.
