Weld-in Nitrous Nozzle Fittings 8pk

The Weld-in Nitrous Nozzle Fittings 8pk from Nitrous Oxide Systems provides a reliable connection solution for custom nitrous oxide injection systems. Designed for fabricators and performance tuners building bespoke NOS setups, these weld-on bungs eliminate the need for threaded ports on engine blocks or intake manifolds. This eight-piece set delivers flexibility for multi-stage nitrous systems or replacement inventory, making it an essential component for serious nitrous builds.

Each fitting features a 1/16 inch NPT female port machined to precise industry standards, allowing secure connection of braided nitrous lines and metering jets. The aluminum construction combines lightweight durability with corrosion resistance, while the natural finish integrates seamlessly into engine bay aesthetics. The weld-on design ensures permanent, leak-free installation; once welded to the target location, these bungs create a solid mechanical bond that withstands high-pressure nitrous delivery cycles. This approach eliminates port blockage common in drilled-and-tapped alternatives and accommodates non-standard mounting locations.

Performance builders and engine shops benefit most from this multi-pack configuration, as staged nitrous systems often require multiple nozzle points for optimized fuel distribution and cylinder pressure management. These fittings suit aluminum and steel manifold substrates, provided proper welding technique is employed to avoid heat distortion. Installation requires basic tig or mig welding capability and careful positioning before permanent bonding. The 8-pack quantity reduces repeat orders for expanding systems or accounts for learning-curve welds during prototype development.
