Deally 5 Piece Forged O2 Sensor Socket Set with Thread Chaser for Automotive Oxygen Sensor Removal and Installation

Stuck oxygen sensors. Damaged wiring harnesses. Stripped threads that turn a simple replacement into a costly repair.

If you’ve ever struggled to remove an O2 sensor without cutting the wires or cross threading the exhaust port—you know standard sockets aren’t built for this job.

Introducing the Deally 5 Piece Forged O2 Sensor Socket and Thread Chaser Set—a purpose built solution for one of the most frustrating tasks in automotive maintenance.

This set includes three specialized sockets: a 1/2 inch drive offset, a 3/8 inch drive offset, and a 3/8 inch drive long-reach—all sized at 7/8 inch (22mm) to fit common oxygen sensor bodies. Each features a wide slotted opening that allows the sensor’s wiring harness to pass through intact, eliminating the need to disconnect or cut wires during removal.

Constructed from forged chrome vanadium steel (CR-V) and finished with a heat treated phosphated coating, these sockets resist deformation, corrosion, and rounding—even under high torque in tight engine bays.

But removal is only half the battle. The set also includes two precision thread chasers: M12 x 1.25mm and M18 x 1.5mm. These tools clean rust, restore damaged threads, and prevent cross threading when installing new sensors—saving time, avoiding exhaust leaks, and extending the life of your vehicle’s mounting ports.

Designed for use on both heated and non-heated oxygen sensors, as well as certain vacuum switches, this kit supports a wide range of domestic and import cars, light trucks, and SUVs with computer controlled fuel systems.

Whether you’re a weekend DIYer or a seasoned technician, this set delivers the durability, access, and functionality needed to complete O2 sensor service correctly—the first time.

Because reliable performance starts with the right tool.
