MateAuto 7-Piece Oxygen Sensor Socket Set with 72-Tooth Ratchet — 22mm Offset Sockets & Thread Chasers

MateAuto 7 Piece Oxygen Sensor Socket Set with Ratchet Wrench is a complete mechanic-grade kit for removing, installing and repairing O2 sensors and their threads quickly and safely.

This compact toolkit bundles specialized sockets, thread chasers and a smooth 72-tooth quick-release ratchet so you can service heated and non-heated oxygen sensors without cutting cables or struggling in tight engine bays. Built from chrome-vanadium and chrome-molybdenum steel with heat treatment and phosphating, the set resists corrosion and stands up to repeated torque and impact during professional or DIY repairs.

How does this set make oxygen sensor jobs faster?

The kit groups the most common O2 sensor sizes and the right accessories to save trips to the tool bench. Offset sockets give access to awkward angles, and the quick-release ratchet speeds socket changes while maintaining fine control in confined spaces.

• Includes 7/8" (22mm) offset sockets for both 1/2" and 3/8" drives.
• Long 3/8" drive socket reaches recessed sensors without adapter swaps.
• 72-tooth ratchet offers better swing clearance in tight engine compartments.
• 3/8" to 1/2" adapter included to match drive sizes on most wrench sets.

What features protect sensor wiring and improve grip?

Each sensor socket is shaped to let the sensor harness pass through the opening so you can remove or install sensors without cutting or stressing wiring. Grooved anti-slip surfaces and an offset profile help you maintain grip and leverage even when access is limited or hands are greasy.

• Generous cable slot prevents wire chafing during removal and installation.
• Anti-slip grooves improve hold with gloved or oily hands.
• Offset socket geometry reduces interference from surrounding components.

Can this kit repair damaged sensor threads and save time?

Yes — the set includes two thread chasers sized for the most common O2 sensor threads so you can clean or restore damaged threads without expensive replacements. Running the chasers through the bore removes rust and cross-threading so sensors seat properly and sealing is improved.

• M12 x 1.25mm and M18 x 1.5mm thread chasers included.
• Chasers fit 3/8" ratchets for quick hand-powered thread cleanup.
• Prevents misalignment and reduces future removal difficulty.

Which vehicles and sensor types is this compatible with?

The tools are designed for a wide range of gasoline and diesel vehicles equipped with electronic oxygen sensors and vacuum switches. They work for heated and unheated O2 sensors and are suitable for many domestic and import models where 22mm sockets and M12/M18 threads are standard.

• Suitable for most cars and light trucks with standard 22mm O2 sensors.
• Works with heated and non-heated sensors and vacuum switches.
• Handy for fleet maintenance, home garages and professional shops.

Who is this for: Mechanics and serious DIYers who want a purpose-built, durable oxygen sensor service kit that reduces removal time, protects sensor wiring and repairs thread damage on the spot. If you routinely remove or replace sensors, perform emissions troubleshooting or maintain a fleet, this compact 7-piece set provides the common sockets, thread tools and a precise ratchet needed to get the job done with fewer tool changes and less risk of part damage.
