Our take on the Lisle 12100 Oxygen Sensor Socket

The Lisle 12100 is a single 7/8-inch (22 mm) oxygen sensor socket with a slot cut down the side so the sensor's pigtail wire can pass through while you turn it. It is made of heat-treated alloy steel with a black oxide finish and is deep enough to clear the sensor body. It is a manual, fixed tool with no moving parts. At $12.51 at JBTools.com as of November 3, 2026, it sits at the low end of its recent range, where it typically sells for roughly $12 to $18.

Best forWeekend DIYers replacing their first O2 sensorHome mechanics with a 7/8-inch or 22 mm sensorShade-tree techs who want a cheap dedicated toolAnyone doing exhaust or emissions work on domestic cars

Pros

Slotted side lets the sensor wire pass through
Deep enough to fit over the full sensor body
Heat-treated alloy steel holds up to rusted threads
Black oxide finish resists corrosion
Cheap enough to keep in a home toolbox

Cons

One size only; does not fit every import sensor
The slot weakens the wall, so it can flex on very tight sensors
No 3/8-inch drive version in this model; check your ratchet fit
Not for sensors with a permanently attached connector that won't pass the slot

Questions and answers

Is the Lisle 12100 worth it?: Yes, if you have a 7/8-inch or 22 mm oxygen sensor to remove. At $12.51 it costs less than most single-use alternatives and lasts for several jobs.
Will it fit my car's oxygen sensor?: It fits most domestic sensors and some imports with a 7/8-inch (22 mm) hex. Check your sensor's hex size and whether its connector fits through the slot before buying.
Does it work with a ratchet or wrench?: It is driven by a ratchet or breaker bar on the hex end. Use a breaker bar on tight sensors, since the slot makes the socket flex under heavy load.
What is in the box?: One oxygen sensor socket. No adapter, case or extra sizes are included.
When is it cheapest?: It is already near the bottom of its range at $12.51 as of November 3, 2026. Watch for small drops around tool sales, but the spread between stores is only a few dollars.
