NOS Female-to-Male Pipe Fitting Adapters for Nitrous Systems

NOS Female-to-Male Pipe Fitting Adapters are precision-engineered plumbing components designed to bridge thread-size differences within nitrous oxide delivery systems. Built to the same exacting standards as NOS's complete line of nitrous hardware, these adapters are an essential part of any well-plumbed nitrous system — whether for street performance or all-out racing.

Key Features:

• Precision-machined construction ensures accurate thread engagement and a consistent, leak-free seal under the high operating pressures of nitrous oxide systems
• Purpose-built for nitrous applications — engineered specifically to meet the plumbing demands of NOS performance systems, not repurposed general-purpose hardware
• Durable, corrosion-resistant materials stand up to the unique chemical and pressure properties of nitrous oxide, ensuring long service life
• Female-to-male thread configuration provides a straightforward, reliable solution for connecting nitrous components with differing thread specifications
• Available in multiple thread configurations to suit a wide range of NOS system plumbing requirements — select the variant that matches your system's needs
• Important fitment note: NOS uses 37° AN fittings throughout its nitrous kits — never mix 37° AN and 45° SAE fittings to avoid potential leaks
