HOHNNYREET O2 Sensor Bung Weld-In with Plug – 2 Sets, 304 Stainless, M18-1.5

Overview

The HOHNNYREET O2 sensor bung weld-in with plug is designed for 1.5–2 inch exhaust pipes, delivering a precise fit and clean welds. The body is crafted from 304 stainless steel, offering excellent corrosion resistance and long-term durability in demanding automotive environments.

Why it stands out

Unlike generic bungs, this weld-in bung follows the pipe’s curvature for a smoother weld seam and more predictable installation. The universal M18 x 1.5 thread provides broad compatibility with standard O2 sensors, helping you move quickly from retrofit to ready-to-run.

• Precise fit for 1.5–2 inch exhaust pipes, promoting clean welds and solid alignment
• 304 stainless steel construction delivers corrosion resistance and a durable finish
• Standard M18 x 1.5 thread ensures compatibility with most oxygen sensors
• Copper o-ring offers high-temperature sealing and a reliable gasket seal after installation

What’s included is simple and practical: two bungs, two plugs, and two copper o-rings. The kit supports dual-sensor projects or handy spare parts for future work, making maintenance more straightforward when you’re in the middle of a project.

Real-world use cases

Imagine upgrading an exhaust system or replacing a worn bung on a mid-size pipe. The weld-in design makes for a tidy, professional look, and the copper o-ring helps maintain a seal as temperatures cycle. The robust stainless body stands up to road dust, moisture, and heat cycles without warping or pitting.

In short, this HOHNNYREET solution focuses on fit, durability, and reliability, offering a practical option for hobbyists and professionals alike. It emphasizes fit and durability for automotive exhaust environments, without implying any medical or performance claims.

Ease of installation and durability

With a smooth 304 stainless steel surface and precise threading, installation is straightforward, and the copper o-ring helps seal against heat and vibration. The material choices resist corrosion and retain a clean appearance over time.

Quality you can trust: each set includes two bungs, two plugs, and two copper o-rings, making it practical for builds that require redundancy or multiple ports.
