MateAuto Oxygen Sensor Socket Set — 7-Piece Kit with 72-Tooth Ratchet and Cable-Passthrough 22mm Sockets

If you service exhaust components, this kit bundles the sockets, thread chasers, adapter, and a 72-tooth quick-release ratchet you need to work on most modern vehicles. Built from CR-V and CR-MO steel with heat-treated, phosphated surfaces, the set is engineered to resist torque, corrosion, and deformation during heavy use. Thoughtful details—offset socket profiles, cable pass-throughs, and anti-slip grooves—help protect sensor wiring and let you reach tight placements that standard sockets can’t.

How does this kit make oxygen sensor service faster and less risky?

The set consolidates dedicated O2 sensor sockets plus thread repair tools so you avoid multiple trips to the toolbox. The ratchet’s 72-tooth mechanism smooths operation in restricted swing spaces, and the cable door prevents wire damage while spinning the sensor free.

• 7-piece combination: two offset 7/8" (22mm) sockets, one long socket, two thread chasers, adapter, and 3/8" ratchet
• 72-tooth quick-release ratchet for fine engagement and easy bit changes
• Socket cable slots keep sensor harness intact during removal
• Offset shapes and long socket access recessed or angled sensors

Which vehicles and sensors will this set fit?

The sockets are sized for common 22mm (7/8") oxygen sensor hexes and the included M12 and M18 thread chasers address typical thread sizes encountered on many gasoline and diesel engines. It’s suited to both heated and non-heated O2 sensors and many vacuum switch fittings.

• 22mm sockets match most O2 sensor hex nuts found on passenger and light-commercial vehicles
• M12 x 1.25 and M18 x 1.5 thread chasers repair or clean standard sensor threads
• Works with sensors that have wiring harnesses thanks to cable passthroughs
• 3/8" drive compatibility for common ratchets and extensions

What makes the tools durable and safe for repeated shop use?

High-alloy CR-V and CR-MO steels combined with heat treatment deliver the hardness and torsional strength needed for seized sensors. Phosphate surface treatment improves rust resistance, while anti-slip grooves and robust offsets increase operator control during demanding extractions.

• CR-V and CR-MO construction for strong anti-torque performance
• Heat-treated and phosphated finish to reduce corrosion and extend life
• Grooved anti-slip socket surfaces improve grip with gloved hands
• Generous cable doors prevent wiring chafing and accidental cuts

How do the thread chasers improve repair outcomes?

Thread chasers clean and restore damaged sensor threads so replacements seat evenly and torque correctly. Using the correct chaser reduces cross-threading risk and lets you reuse threaded ports that would otherwise require time-consuming rework.

• M12 x 1.25 and M18 x 1.5 chasers match standard sensor port pitches
• Designed to be used with a 3/8" ratchet for controlled turning force
• Removes rust, corrosion, and debris that cause misalignment or binding
• Shortens repair time by avoiding full re-tapping or replacement of housings

Who this set is for: professional mechanics and DIYers who work on exhaust and emissions components and need a compact, shop-ready O2 sensor toolkit. It’s especially useful for technicians who regularly encounter seized or wire-harnessed sensors and anyone looking to reduce downtime with dedicated sockets, thread repair tools, and a high-tooth-count ratchet for tight spaces.
