Oxygen Sensor Socket with Wire Slot – 22mm, 1/2-Inch Drive

Brief Overview

This is a purpose-built oxygen sensor socket designed to solve a common workshop challenge: accessing oxygen sensors in tight engine bay spaces while keeping the sensor wire protected and routed. The 22mm socket accommodates both heated and unheated oxygen sensors across major vehicle platforms (VW, Audi, BMW, Mercedes, Ford, Opel, Seat, Renault, and others). The critical feature here is the longitudinal slot running through the socket cup—it allows the sensor lead to exit while the socket engages the hex, eliminating the need to disconnect wiring during sensor replacement. For shops handling volume oxygen sensor replacements, consider pairing this with a multi-piece sensor socket set to cover additional sensor sizes and reduce changeover time.

Key Features

• Slotted Cup Design: Side slot allows sensor lead to pass through unobstructed during removal and installation
• 22mm Socket Size: Fits standard oxygen sensors across European and Japanese platforms
• 1/2-Inch Drive: Compatible with standard ratchets and impact tools
• Compact Dimensions: 55mm overall length with 50mm socket depth for access in confined spaces
• Multi-Point Drive: 12-point internal drive for secure engagement without cam-out
• Dual Application: Works with both heated and unheated oxygen sensor designs
• Durable Metal Construction: Dark-finished steel for corrosion resistance in high-heat engine environments

Business Advantages for Resellers

Shop Productivity: Oxygen sensor jobs are high-frequency repairs in any general service shop. Having the correct socket eliminates the disconnect-reconnect wire handling that slows technicians down. A single socket is a low-inventory burden with consistent demand.

Vehicle Coverage: The 22mm size covers a broad range of OEM sensors across Volkswagen Group (VW, Audi), BMW, Mercedes, and Ford platforms—the core vehicles in most European-focused shops. Stock depth is minimal; impact is maximum.

Consumable Job Confidence: Technicians often dread oxygen sensor jobs due to tight spaces and wiring concerns. A proper slotted socket removes that friction and positions your shop as prepared and efficient.

Upsell Path: Start with this single socket, then introduce shops to a complete sensor socket combo set to capture additional sensor sizes and thread-chasing tools in one transaction.

Why This Socket Matters

Oxygen sensor replacement is a staple job, but poor tooling turns it into a frustration. Standard sockets don't account for the sensor lead—technicians either disconnect the harness (extra time) or fight with a socket that doesn't fit the space. This socket eliminates both problems. The slot is engineered; the depth is correct; the drive is robust.

For distributors, this is a no-brainer inclusion in any diagnostic or general repair toolkit offering. Low cost per unit, high perceived value to end shops, and repeat orders as sensors wear out.
