45° Saddled 304SS O2 Bung — M18x1.5

Stop fighting clearance issues mid-build — this 45 degree saddled O2 bung gives you the right angle, the right thread, and a weld-ready fit the first time.

Why Fabricators Keep This One in Stock

Angled Where It Counts

The 45° profile helps keep your O2 or wideband sensor clear of tight turbo-back routing, chassis rails, and heat shielding — no grinding, no jury-rigging, and no sensor damage from awkward mounting.

Saddled Base for a Clean, Confident Weld

The pre-saddled base conforms to the curved surface of your exhaust tubing, closing the gap before you strike an arc. The result is full, consistent weld contact — not the gap-bridging you get with a flat-base bung on round pipe.

M18x1.5 — The Universal O2 Thread

The standard M18x1.5 thread pitch accepts virtually every narrowband and wideband O2 sensor on the market, from OEM replacements to Bosch LSU 4.9-based controllers. If you're running a lambda sensor, it fits.

304 Stainless Steel Throughout

304SS handles the thermal cycling and corrosive exhaust gases that eat through mild steel bungs over a season. It's a natural match for stainless turbo-back and diesel exhaust systems, and it won't rust out from harsh winter road salt finding its way under the vehicle.

Stock Up Without Breaking the Budget

At this price point, it makes sense to bung every collector, test pipe, and downpipe in one go — so you're never cutting into a finished pipe to add a sensor later.

Stocked in Canada, Ships Fast Across North America

Sourced and stocked by Black Sheep Industries, so you're not waiting on overseas freight to finish your build.

The right angle makes all the difference — weld it in right the first time.
