DURATECH O2 Oxygen Sensor Socket Set — 5‑Piece Kit with 7/8" Sockets & Thread Chasers, Heat‑Treated Alloy Steel

DURATECH 5PCS O2 Oxygen Sensor Socket Set is a five-piece tool kit designed to remove, install, and service oxygen sensors and vacuum switches safely and efficiently.

This compact set brings together three purpose-made oxygen sensor sockets plus two thread chasers so you can tackle seized sensors, damaged threads, and awkward wiring runs without improvising. Each socket is engineered to allow the sensor wiring to pass through the tool while the slotted square drive reduces slipping on your ratchet. Constructed from heat-treated alloy steel with a phosphated finish, the set meets ANSI/ASME quality expectations and is intended for repeated garage or roadside use.

How does the DURATECH set make sensor removal easier?

The sockets have a wide wire gate so you can pull the sensor harness through the tool instead of cutting or straining the wire. Offset and long socket shapes reach sensors in tight or recessed locations and the slotted square-hole design helps maintain a secure connection to your ratchet.

• 1/2" drive offset 7/8" (22mm) socket for heavy-duty ratchets
• 3/8" drive offset 7/8" (22mm) socket for standard ratchets
• 3/8" drive long 7/8" (22mm) socket for deep or recessed sensors
• Wide wire gate preserves sensor wiring during removal

What do the included thread chasers do and when should I use them?

The M12 x 1.25mm and M18 x 1.5mm thread chasers clean, re-cut, and restore oxygen sensor threads in the exhaust bung. Use them before installing a new sensor if threads are corroded, dirty, or slightly damaged to prevent cross-threading and ensure a tight seal.

• M12 x 1.25mm chaser fits smaller sensor bungs
• M18 x 1.5mm chaser addresses larger exhaust threads
• Use with a 3/8" ratchet for controlled re-tapping
• Removes rust and debris to restore proper thread engagement

What materials and design features ensure durability and safety?

All sockets and chasers are forged from high-quality alloy steel, then heat-treated and phosphated for corrosion resistance and extended life. The slotted square drive reduces ratchet slip while the open wire gate prevents damage to sensor leads during extraction or installation.

• Heat-treated alloy steel for strength under torque
• Surface phosphating to resist rust and wear
• Slotted square hole for a firmer ratchet connection
• Wire gate sized to protect sensor harnesses

Which vehicles and tasks is this kit compatible with?

The DURATECH O2 socket set is intended for most modern vehicles that use threaded oxygen sensors or vacuum switches, including heated and non-heated types. The range of socket styles and thread chasers covers common sensor sizes, making it useful for engine diagnostics, part replacement, or routine exhaust maintenance.

• Works on heated and non-heated oxygen sensors
• Fits many passenger cars, trucks, and light SUVs with threaded sensors
• Useful for removing, installing, inspecting, and servicing sensors
• Saves time compared with cutting wires or using improvised tools

Who is this for? Mechanics, home DIYers, and fleet technicians who service exhaust systems will benefit from the DURATECH 5PCS O2 Oxygen Sensor Socket Set. If you routinely replace oxygen sensors, restore damaged threads, or need a reliable, compact set for mobile repairs, this kit supplies the commonly required socket sizes and thread chasers in a durable, workshop-ready format.
