7/8 Inch O2 Sensor Socket

The Teng Tools AT380 is an offset socket for lambda oxygen sensors, 7/8 inch, on a 3/8 inch drive. The drive sits on an arm to one side of the socket, which gives access to oxygen sensors in areas where a straight socket cannot reach. A cutout down the side of the socket lets the sensor wire pass through, so the lead can stay on while you work.

Use a 3/8 inch drive ratchet or extension on the offset arm to break the sensor loose and to run it back in. The head is fixed, not flexible. The socket body is 30 mm (1.2 in) long and the whole piece weighs 222 g (7.8 oz). It is chrome vanadium with a satin finish.

This is one of the Teng Tools special auto sockets for various applications, and the same socket is supplied in the Teng Tools TTSS07 set. As a single piece it replaces a lost socket from that set, or gives a home garage, service bay or fleet workshop a dedicated oxygen sensor removal tool, or 02 sensor removal tool, for exhaust work.

This socket is 7/8 inch, so check the hex on the sensor before you order.

What you get: one 3/8 inch drive offset oxygen (lambda) sensor socket, 7/8 inch. Ratchet, extension and the TTSS07 set are not included.

• The 3/8 inch drive sits on an offset arm beside the socket rather than directly above it. Teng Tools designs it this way to give access to oxygen sensors in areas where a straight socket cannot reach. It works as an O2 socket and as an oxygen sensor removal socket, for taking the old lambda sensor out and running the new one in.
• The socket is 7/8 inch. A cutout down the side lets the sensor wire pass through, so this oxygen sensor tool goes over the sensor with the wire still attached to it. The size is stated in inches by Teng Tools: check the hex on your sensor against it before you order.
• The socket body is 30 mm (1.2 in) long. Teng Tools pairs that compact length with the offset drive so the socket reaches sensors in restricted locations. Fit a 3/8 inch drive ratchet or extension to the arm. Ratchet and extension are not included: this listing is the O2 sensor tool alone.
• Made from chrome vanadium with a satin finish. It weighs 222 g (7.8 oz), and it has a fixed head, not a flexible one. Teng Tools lists it among its special auto sockets for various applications, filed under engine tools. Use it as an O2 sensor removal tool and again to fit the new lambda sensor.
• Teng Tools supplies the same offset socket in its TTSS07 set. Buy it singly to replace one that has gone missing from the set, or to keep a dedicated socket for lambda sensors in the drawer instead of improvising with a standard deep socket when a sensor needs changing.
