Moroso 22739 Weld-In Oxygen Sensor Bung Fitting M18 x 1.5

The Moroso 22739 is a weld-in oxygen sensor bung fitting designed for performance exhaust applications. This fitting allows builders to add an O2 sensor port to aftermarket exhaust pipes, headers, and custom fabrications that were not originally equipped with a sensor bung.

Key Features:

• Weld-in design – mounts directly to exhaust tubing or headers for a secure, leak-free installation
• M18 x 1.5 thread size – compatible with virtually all standard oxygen and O2 sensor thread patterns
• Ideal for use when replacing stock exhaust systems with aftermarket pipes or headers
• Part of Moroso's complete oxygen sensor fitting lineup (bungs, plugs, and adapters)
• Manufactured by Moroso Performance Products, a trusted name in racing and street performance since 1968

Moroso Performance Products has supplied high-quality components to everyone from grassroots racers to top-level NASCAR and NHRA/IHRA teams. The 22739 O2 sensor bung fitting is a straightforward, professional-grade solution for any custom exhaust build requiring oxygen sensor capability.
