Burns Stainless Announces Their New Flanged O2 Sensor Bung

Leave it to Burns Stainless to design an O2 sensor bung (ring) that provides maximum support to the O2 sensor and tubing. The new flanged design distributes the load of the sensor and wire harness over a larger area, minimizing cracking and breakage. With a conventional O2 sensor ring, metal fatigue occurs, especially with thin wall tubing. The fatiguing  leads to cracks and eventually to complete failure. The company states their new O2 ring greatly reduces the issue, welds easily, and is fully CNC'd 304 Stainless Steel!



Currently the company offers these flanged O2 rings for two sizes of tubing: 2″ for header primaries and 3″ for tailpipe. These rings are used extensively in NASCAR, NHRA, ALMS and other professional race series.  Without modification to the flanges, the rings will fit approximately 0.25″ larger or smaller diameter tubing and will secure an 18mm sensor.  



Burns Stainless also offers straight cut and radiused O2 sensor rings for thick wall applications.  For more information visit the Burns Stainless website www.BurnsStainless.com
