Cal-Van Tools 843 Oxygen Sensor Socket 7/8" (22mm) Made in USA

The Cal-Van Tools CV843 Oxygen Sensor Socket is a professional-grade specialist tool designed for the installation and removal of oxygen (O2) sensors without damaging the sensor wiring. Featuring a deep slotted design, the socket allows the sensor wiring harness to pass through the side opening, enabling easy access in confined engine bay locations.

Manufactured from high-quality alloy steel and finished with a durable black oxide coating, the CV843 is built to withstand demanding workshop use. The 6-point socket profile provides secure engagement with the sensor, helping to reduce the risk of rounding during removal and installation.

Designed for versatility, the socket can be driven using a standard 1/2" square drive ratchet or breaker bar, or with a 7/8" hex wrench where access is restricted.
