Camotokiit Fuel Injection Oxygen Sensor Bung Kit M18 x 1.5 — Clamp-On Stainless Steel, No-Weld Installation

The Camotokiit Fuel Injection Oxygen Sensor Bung Kit 60012 is a stainless-steel, clamp-on sensor fitting that lets you add an M18 x 1.5 oxygen sensor to a round exhaust pipe without welding.

This compact kit provides a practical way to mount an oxygen sensor into standard exhaust tubing for diagnostics, tuning, or replacement of a damaged bung. Everything needed for a no-weld installation is included: a threaded sensor bung, a heat-resistant gasket, and two stainless-steel band clamps. The design suits round exhaust pipes and accepts an M18 x 1.5 threaded sensor, making it a universal aftermarket solution for many vehicles and custom exhaust setups.

How does this bung kit install without welding?

Installation requires a single 3/4-inch hole drilled into the exhaust tube. The gasket seats against the pipe, the bung is set in place, and the included band clamps compress the assembly tightly to form a secure mechanical seal.

• Drill a 3/4-inch (approx. 19 mm) hole in the exhaust pipe at the chosen location.
• Place the heat-resistant gasket over the hole to create a seal.
• Position the threaded sensor bung and wrap the band clamps around the pipe.
• Tighten clamps evenly until the bung is firmly seated and leak-free.

Will this fit my oxygen sensor and exhaust tubing?

The threaded boss accepts sensors with an M18 x 1.5 thread, which is a common size for many oxygen and wideband sensors. It is designed to clamp onto standard round exhaust piping rather than specialized oval or flattened sections.

• Thread compatibility: M18 x 1.5—confirm your sensor's specification before purchase.
• Pipe compatibility: standard round exhaust tubes; ensure sufficient circumference for both clamps.
• Universal fit: ideal for many aftermarket and OEM-style sensors that use M18 threading.

What materials and parts are included in the kit?

The kit is constructed from stainless steel for corrosion resistance under high-heat exhaust conditions. It includes the main sensor bung, a gasket to help seal the hole, and two band clamps sized to secure the fitting to the pipe.

• 1x stainless-steel sensor bung with M18 x 1.5 threads.
• 1x heat-resistant gasket to prevent exhaust leaks.
• 2x stainless steel band clamps for a clamp-on, no-weld connection.
• Simple hardware only—no welding gear or additional adapters required.

How durable and serviceable is the clamp-on installation?

Stainless-steel construction offers good resistance to rust and high temperatures common in exhaust systems. The clamp-on approach keeps the sensor accessible: you can remove or reposition the bung without cutting or welding, which is convenient for tuning or replacement.

• Corrosion resistance from stainless-steel components extends service life.
• No permanent modification—easy removal or relocation of the bung.
• Gasket and clamps can be replaced independently if wear occurs.

Who is this for: The Camotokiit 60012 Oxygen Sensor Bung Kit is aimed at mechanics, tuners, DIY enthusiasts, and custom exhaust fabricators who need a quick, cost-effective way to add or replace an oxygen-sensor port without welding. If you have an oxygen or wideband sensor with an M18 x 1.5 thread and a round exhaust pipe where a temporary or adjustable installation is preferable, this kit gives a straightforward, serviceable solution.
