NITROUS EXPRESS 3000PSI NHRA Safety Blow-Off Fitting – Chrome & DF5 Valves

Description

NITROUS EXPRESS 3000PSI NHRA Safety Blow-Off Fitting – Chrome & DF5 Valves

Safety is paramount when dealing with high-pressure nitrous oxide systems. The Nitrous Express (NX) NHRA Safety Blow-Off Fitting is designed to provide a secure and reliable connection between your bottle valve and a blow-down tube.

In the event of an over-pressure situation (such as the bottle getting too hot), the burst disc in your valve will rupture. Without this fitting and a corresponding tube, the nitrous would vent directly into the boot or cabin of your vehicle. This fitting allows you to redirect that gas safely to the exterior of the car, a requirement for many motorsport organisations and drag strips worldwide.

Engineered for Compliance

This fitting is specifically designed to meet NHRA (National Hot Rod Association) safety regulations, which are the gold standard for drag racing safety. It features a high-quality finish and precision threading to ensure a leak-free seal under extreme pressure.

Compatibility & Installation

This specific model (Part #11709) is designed to fit all NX Chrome and DF5 valves equipped with female threads. It serves as the bridge between the valve’s safety port and a standard blow-down tube (usually -8AN).

Key Features:

• Essential Safety: Redirects high-pressure gas outside the vehicle during an over-pressure event.

• Track Legal: Complies with NHRA and major UK drag racing safety requirements.

• Durable Construction: Built to withstand the high-velocity discharge of liquid nitrous oxide.

• Precision Fit: Designed specifically for NX Chrome and DF5 valves with female safety ports.

• Simple Integration: Easy to install as part of a complete safety blow-down kit.

Technical Specifications:

Why Do You Need This?

If you plan on racing at professional tracks or sanctioned events, a safety blow-down system is often mandatory. Beyond the rules, it provides peace of mind for the driver. By using a genuine Nitrous Express fitting, you ensure that the safety equipment is just as high-quality as the performance parts on your engine.

Note: This product is the fitting only. A blow-down tube and burst disc are required for a complete safety system.

Nitrous Express (NX) was founded in 1996 with the goal of exceeding existing nitrous systems in performance. The company’s advantage stemmed from a clean slate – their components were built from the ground up with performance modifications already integrated. This offered customers superior results compared to competitors, who often required expensive modifications to achieve similar gains. NX’s initial impact was significant, offering a breath of fresh air to the market. Over the next two decades, they continued to refine their nitrous products while expanding their offerings to include a range of impressive nitrous and water-methanol products.
