One-piece, Stellite-tipped construction enhanced by a specialized nitriding process that builds surface resistance and reduces friction. 🔧

The treatment deposits microscopic layers to improve wear properties and outperforms hard chromium and electroplated nickel in corrosion resistance and longevity. ⚙️

Engineered for lightweight performance with flow-optimized profiles, it runs reliably with both leaded and unleaded fuels and performs well in cast-iron and bronze guides for precise oil control and heat dissipation. 🇺🇸

Made in the USA.
