The Nitrous Express 11712L is a 3000 PSI safety burst disc designed specifically for NX Lightning 500 bottle valves. The 11712L is a critical safety component in any nitrous oxide system equipped with Lightning 500 hardware. When bottle pressure exceeds the rated 3000 PSI threshold due to extreme heat exposure, overfilling, or other abnormal conditions, the 11712L disc ruptures in a controlled manner to safely vent the bottle and prevent catastrophic valve or bottle failure. The 11712L is a direct replacement burst disc manufactured to the exact pressure rating and thread specification of the original Lightning 500 valve. This is a universal fitment component for any vehicle running a Nitrous Express Lightning 500 bottle valve. Note: per Nitrous Express product restrictions, this item is not for sale or use in California.

Installation Notes
- The burst disc installs in the safety disc port of the NX Lightning 500 bottle valve
- Inspect the burst disc before each use and replace immediately if any deformation, corrosion, or damage is present
- Always replace the burst disc after any overpressure event or if the bottle has been exposed to excessive heat
- Do not exceed the rated bottle fill pressure for Lightning 500 valves
- Pair with the NX 11708-90 or compatible blow-down tube kit to safely route discharge away from the vehicle interior if the disc ruptures
- Refer to Nitrous Express installation documentation at nitrousexpress.com for full safety instructions
Frequently Asked Questions
What is the Nitrous Express 11712L burst disc for?
The 11712L is a safety burst disc for the Nitrous Express Lightning 500 bottle valve. It is a sacrificial pressure relief device rated to rupture at 3000 PSI, providing a controlled release path for nitrous oxide if bottle pressure exceeds safe limits due to heat, overfilling, or other abnormal conditions.
What vehicles does the 11712L fit?
The 11712L is a universal fitment component that fits any vehicle equipped with a Nitrous Express Lightning 500 bottle valve, regardless of year, make, or model.
How often should I replace the burst disc on my nitrous bottle?
Replace the 11712L burst disc after any overpressure event, after the bottle has been exposed to extreme heat (such as sitting in direct sun in a race car), or any time visible deformation or damage is present. Many racers replace the burst disc on a regular inspection schedule as a precautionary measure.
Can I use the 11712L with other Nitrous Express valves besides the Lightning 500?
The 11712L is specifically designed for the Lightning 500 bottle valve. Other Nitrous Express valves may use different burst disc part numbers and pressure ratings. Confirm the correct part number for your specific valve before ordering.
Is the Nitrous Express 11712L available in California?
No. Per Nitrous Express race-use product restrictions, the 11712L is not for sale or use in California.
What happens if I run a nitrous system without a burst disc?
Operating a nitrous system without a properly rated burst disc removes a critical safety mechanism. Without it, an overpressure event could cause the bottle valve or bottle itself to fail violently. Always ensure the correct burst disc is installed and in good condition before use.
What should I pair with the 11712L for a complete safety setup?
Nitrous Express recommends pairing the burst disc with a blow-down tube kit such as the 11708-90 to route any discharge safely out of the vehicle in the event of a rupture.
What is the warranty on the Nitrous Express 11712L?
Nitrous Express covers their products with a limited warranty against manufacturer defects. Burst discs are consumable safety items and are not warranted for use beyond their rated pressure or after a rupture event.
