The Weld-In Fitting Evac from KEVKO OIL PANS & COMPONENTS is a precision crankcase evacuation fitting engineered for serious engine builders and performance enthusiasts. This 1/2 inch NPT threaded nipple serves as a critical connection point in modern PCV (positive crankcase ventilation) systems, allowing pressurized gases to safely exit the crankcase while maintaining engine sealing integrity. Whether you're building a competition engine, restoring a classic, or upgrading an existing power plant, this weld-on fitting ensures reliable crankcase evacuation performance for sale to professional shops and dedicated DIY builders.
Constructed from durable steel with a zinc oxide protective coating, the Weld-In Fitting Evac resists corrosion and thermal cycling that characterize high-performance engine environments. The weld-on design eliminates threaded assembly concerns and provides superior structural integrity compared to bolt-in alternatives, ensuring the fitting remains secure under sustained boost, vacuum fluctuations, and vibration. Its compact 2.9 x 0.85 x 4 inch profile weighs only 0.19 lbs, minimizing added mass while the 1/2 inch NPT thread standard ensures compatibility with industry-standard PCV hoses, catch cans, and evacuation components. The precision engineering reflects KEVKO's reputation for manufacturing premium oil pan systems and related crankcase management solutions.
This fitting is ideal for custom engine builders, race engine specialists, and restoration professionals integrating modern PCV systems into classic applications or upgrading stock crankcase ventilation. Installation requires welding directly to an oil pan or custom fabricated component, making it particularly suited for bespoke engine builds where threaded ports are unavailable or undersized. The zinc oxide finish provides baseline corrosion resistance suitable for street and competition use, though additional protective coating may be desired in salt-spray or marine environments. Verify your oil pan or component accepts 1/2 inch NPT connections and confirm welding capability before purchase.
