ITEQ Oxygen Sensor Socket and Thread Chaser Set — 5-Piece 22mm Sockets with M18 & M12 Chasers, Deep & Low-Profile Crowfoot

ITEQ 5-piece oxygen sensor socket and thread chaser set is a complete kit for removing, installing, inspecting and repairing heated and non-heated O2 sensors on most modern vehicles.

This ITEQ tool set combines three purpose-built socket wrenches and two thread chasers to handle tight locations, protect sensor wiring, and restore damaged sensor threads so replacements seat correctly. It’s built for both home mechanics and professional technicians who need a compact, versatile solution for oxygen sensor service across a wide range of makes and models.

How does this set make oxygen sensor removal easier?

The sockets are designed with a side cutout that gives clearance for sensor wiring harnesses so you can loosen and remove sensors without straining the wires. Multiple socket shapes and drive sizes let you reach sensors in confined engine bays or exhaust manifolds without having to disconnect other components.

• Side-cut sockets allow access around wires and connectors.
• Includes deep broach, low-profile crowfoot, and offset crowfoot styles.
• Works with common 3/8" and 1/2" ratchet or breaker bar drives.
• 6-point 7/8" (22mm) opening fits standard hexagon oxygen sensors.

Which thread chasers are included and why are they useful?

The set contains two thread chasers sized for common O2 sensor threads so you can clean and repair damaged or corroded threads before installing a new sensor. Restoring threads improves seating, reduces leaks, and prevents cross-threading during reinstallation.

• M18 x 1.5 mm thread chaser for many upstream sensors.
• M12 x 1.25 mm thread chaser for smaller sensor mounts and vacuum switches.
• 3/8" drive compatibility for use with the included sockets or a ratchet.
• Prepares threads to ensure proper torque and sealing of replacement sensors.

Will these sockets fit the tight spaces under modern engines?

Yes — the kit was designed with varied socket profiles to tackle different clearances. The extra-deep broach reaches recessed sensors, the low-profile crowfoot fits cramped engine compartments, and the offset crowfoot lets you approach sensors at awkward angles without removing other parts.

• Extra-deep broach socket: 3-1/8" length for recessed sensors.
• Low-profile crowfoot: 1-1/4" length for tight engine bays.
• Offset crowfoot: 1-15/16" length for angled access.
• Use with ratchet, breaker bar, or extension for reach options.

How durable and compatible is the ITEQ sensor socket set?

Constructed for workshop use, the sockets use a 6-point 22mm opening that matches standard oxygen sensor hexes and drive sizes common to most hand tools. The side cutouts are shaped to reduce wire damage while providing the clearance needed for modern sensor harnesses.

• 6-point 7/8" (22mm) socket opening for secure grip on sensor hexes.
• Compatible with both 3/8" and 1/2" drive tools for flexibility.
• Thread chasers prevent installation problems from damaged threads.
• Robust construction suited to frequent use in garages and shops.

Who is this for: The ITEQ 5-piece oxygen sensor socket and thread chaser set is aimed at DIY enthusiasts, automotive technicians, and fleet maintenance crews who work on vehicular emissions systems. It’s particularly useful if you frequently change oxygen sensors, work on vehicles with tight engine or exhaust access, or need a compact kit that both removes sensors safely and repairs sensor threads for reliable replacements.
