Super Duty O2 Wrench 6pt/12pt

The Schley Products 88750B is a professional-grade O2 sensor wrench designed for automotive exhaust work. Its dual 6-point and 12-point configuration fits a range of sensor flats. The tool is built for high-torque removal of seized oxygen sensors. It ships new from the manufacturer.

Suited for technicians

This wrench suits anyone needing a dedicated O2 sensor tool with two drive options in one. It is not for general-purpose fastener work or buyers who need a full wrench set. Users requiring impact-rated sockets or offset designs for tight clearances should look at other tools.

Check your sensor flats and access space

Verify the oxygen sensor hex size matches the 6pt or 12pt openings before ordering. Confirm there is enough swing room around the exhaust bung for a standard wrench handle. Ensure your drive tools match the wrench's drive specification. Orders over 75 ship free from the maker.

Questions about this item

What size oxygen sensor does the 88750B wrench fit?

The 6-point and 12-point openings are designed for standard oxygen sensor hex sizes found on most vehicles.

Can I use this wrench on a rounded sensor that an open-end wrench slips on?

Yes, the 12-point box end engages more flats, giving better grip on damaged or corroded sensor nuts.

How do I confirm the wrench is seated correctly before applying force?

The box end should sit fully flush on the sensor hex with no rocking; the offset handle then clears surrounding pipes for a straight pull.
