MateAuto 7PCS Oxygen Sensor Socket Set

The MateAuto 7PCS Oxygen Sensor Socket Set is a complete toolkit designed to simplify removing, inspecting, and replacing oxygen sensors in modern engines. This kit is built for both home mechanics and professional shops, offering a balanced blend of precision, leverage, and durability. Each piece is engineered to help you approach sensor work with confidence, whether you are tackling routine maintenance or a more involved repair in a crowded engine bay.

Complete configuration for efficient maintenance

Included in the set are a variety of sockets and chasers that cover common needs during sensor service. The kit provides a 1/2 in drive 7/8 in offset sensor socket, a 3/8 in drive 7/8 in offset sensor socket, a 3/8 in drive 7/8 in long sensor socket, two thread chasers (M12 x 1.25 and M18 x 1.5), a 3/8 in drive to 1/2 in adapter, and a 3/8 in drive 72 tooth quick-release ratchet. This assortment is designed to fit most sensor styles found across many vehicles, enabling you to complete sensor tasks in fewer steps.

• 1/2 in drive 7/8 in offset sensor socket (22 mm)
• 3/8 in drive 7/8 in offset sensor socket (22 mm)
• 3/8 in drive 7/8 in long sensor socket (22 mm)
• M12 x 1.25 thread chaser
• M18 x 1.5 thread chaser
• 3/8 in drive to 1/2 in adapter
• 3/8 in drive 72 tooth quick-release ratchet

Durable construction and safety design

This set is built from high quality CR-V and CR-MO steels. Heat treated and phosphated finishes provide strong hardness and excellent corrosion resistance, helping the tools hold up under challenging conditions. A thoughtfully designed cable door lets cables pass through without damage, while the socket features an offset structure and grooved anti-slip surface to improve grip and control when working in tight spaces.

• High quality CR-V and CR-MO with enhanced hardness
• Heat treatment and phosphating for corrosion resistance
• Cable door for safe cable clearance
• Grooved anti-slip design and offset geometry for secure operation

Complete set, practical maintenance

Two thread repair tools are included to address damaged threads and misalignment, potentially reducing maintenance time and increasing reliability when servicing sensors. The combination of O2 sensor sockets, thread chasers, and the quick-release ratchet makes routine sensor work feel more efficient and less frustrating, especially for those frequently performing repairs on electronic engine systems.

• Two thread chasers for M12 and M18 sensors
• Two socket sizes plus a long variant for restricted access
• 3/8 to 1/2 adapter and a 72-tooth ratchet for smooth operation

Wide compatibility and practical use

Designed to fit most models with electronically controlled engines, the set is suitable for removing, inspecting, and replacing both heated and non-heated oxygen sensors as well as vacuum switches. It is a practical upgrade for any vehicle repair toolkit, helping to save time and effort on a range of sensor related tasks.
