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

This professional-grade kit groups the most-used oxygen sensor sockets and accessories into one toolbox-ready package so you can remove, inspect, and reinstall heated and non-heated O2 sensors faster and with fewer damaged wires or stripped threads. Built from CR-V and CR-MO steels with heat-treatment and phosphating, the set was designed to resist wear and corrosion and to work in tight engine bays where access and cable clearance matter.

How does this set make oxygen sensor removal easier?

The sockets are offset and grooved to improve grip and reach behind brackets or manifold heat shields while preserving the sensor wiring. The generous cable door lets sensor leads pass through the socket without pinching, reducing the chance of wire damage during removal. A 3/8" to 1/2" adapter and a 72-tooth quick-release ratchet provide the right leverage and fine-tooth engagement to work in confined spaces.

• Offset 7/8" (22mm) sockets for improved clearance and reach.
• Large cable door prevents wire pinching and allows safe removal.
• 72-tooth ratchet yields 5° swing arc for tight locations.
• 3/8"–1/2" adapter expands drive compatibility.

What thread repair and anti-damage features are included?

The kit includes M12 x 1.25 and M18 x 1.5 thread chasers to restore damaged sensor ports and remove rusted or misaligned threads before installation. Using the chasers prevents cross-threading and speeds up reassembly. The hardened materials and phosphated finish on these tools help them cut and clean threads while resisting galling and corrosion.

• M12 x 1.25 and M18 x 1.5 thread chasers for common sensor ports.
• Hardened CR-MO construction for cutting strength and durability.
• Compatible with a 3/8" ratchet for controlled thread repair.
• Helps prevent thread misalignment and reduces rework time.

Which vehicle types and sensor styles will this kit work on?

Designed for wide automotive compatibility, the MateAuto set fits most modern gasoline engines that use electronically controlled oxygen sensors, including heated and unheated styles. It is suitable for sensor removal, inspection and replacement on passenger cars, SUVs and many light trucks. Always verify thread size and sensor hex before use to confirm fit for specific models.

• Fits most vehicles with 7/8" (22mm) sensor hexes.
• Works on heated and non-heated O2 sensors and some vacuum switches.
• Includes adapter and multiple drive sizes for workshop flexibility.
• Useful on passenger cars, SUVs, and many light trucks.

How durable and safe are the sockets and ratchet during repeated use?

Made from high-quality CR-V and CR-MO alloys with heat treatment and phosphating, each component resists deformation, torque stress and corrosion typical in engine compartments. The grooved anti-slip socket exterior and offset profile improve control while the cable aperture protects sensor wiring. The quick-release ratchet offers reliable drive engagement and long service life in professional or home garages.

• CR-V and CR-MO steel resists wear and high torque loads.
• Phosphated finish improves corrosion resistance in humid conditions.
• Anti-slip grooves enhance grip under oily or greasy conditions.
• Quick-release 72-tooth ratchet for dependable, low-swing operation.

Who this is for: The MateAuto 7 Piece Oxygen Sensor Socket Set is aimed at professional mechanics, mobile technicians and DIY enthusiasts who need a compact, rugged kit for routine O2 sensor service and thread repair. If you frequently work on exhaust or fuel-management sensors, require safe cable clearance, or want a reliable set that reduces damaged threads and wasted time, this kit delivers the core tools to get the job done cleanly and quickly.
