7/8" (22mm) Low Profile Offset 3/8" Drive Oxygen Sensor Socket - OTC Tools and Equipment

The OTC 4673-7 Oxygen Sensor Socket is specifically engineered for professional technicians facing the challenge of accessing oxygen sensors in restricted or obstructed locations. Its unique low-profile and offset design provides direct engagement with O2 sensors positioned deep within exhaust systems or crowded engine bays, significantly reducing the need for extensive component disassembly. This specialized tool enables efficient removal and installation of oxygen sensors, saving valuable time in the service bay.

Key Features

• Low-Profile, Offset Design: Engineered to bypass common obstructions such as crossmembers, heat shields, and tight firewall areas, allowing direct access to sensors without excessive component removal.
• Universal 7/8" (22mm) O2 Sensor Fit: Precisely sized to fit the standard oxygen sensor hex found on a wide array of domestic and import vehicles, including popular GM, Ford, Chrysler, Honda, and Toyota applications.
• 3/8" Drive Compatibility: Designed for seamless integration with standard 3/8" drive ratchets, extensions, and breaker bars, providing controlled torque application and versatile access from various angles.
• Professional-Grade Construction: Manufactured from durable materials to withstand the high torque often necessary for heat-cycled or seized oxygen sensors, ensuring reliability and preventing socket deformation under demanding use.
• Positive Engagement on Sensor Hex: Features an internal design that minimizes slipping and rounding of the sensor hex, protecting both the sensor and the threads in the bung or catalytic converter during service.

Applications

This tool facilitates the precise removal and installation of 7/8" (22mm) threaded oxygen (O2) sensors across a broad spectrum of passenger vehicles and light trucks. It is particularly useful for accessing upstream and downstream sensors located near manifolds, catalytic converters, and mid-pipe sections where clearance is severely limited. The OTC 4673-7 supports critical emissions diagnostics, drivability troubleshooting, and routine O2 sensor replacement, thereby reducing labor time by often eliminating the need to drop exhaust components.
