Spark Plug Socket Proxxon 23 442 — professional spark plug wrench accessory

Proxxon 23 442 is a spark plug socket designed for removing and installing automotive spark plugs. Manufactured by Proxxon, this dedicated accessory provides a precise fit for compatible spark plugs and is intended for use with appropriate drive tools to ensure safe torque transfer during maintenance tasks. The socket is produced for workshop and mobile repair applications where a reliable connection to the spark plug hex and soft rubber insert for protection of the ceramic are required.

Advantages

The spark plug socket offers a tight, accurate fit that reduces the risk of rounding the plug hex and a protective internal insert that grips the plug to prevent dropping during removal or installation. Its construction provides good torque transmission when used with compatible ratchets or extension bars, and the tool is suitable for repetitive workshop use as well as mobile servicing. The socket's dimensions and finish make it easy to position in confined engine bays while maintaining durability under normal workshop conditions.

Suitable for

• Removal and installation of automotive spark plugs
• Workshop engine maintenance and tune-ups
• Mobile vehicle repair and roadside spark plug replacement
• Use with compatible drive tools such as ratchets and extension bars

Key specifications

• Designed specifically for spark plug hex engagement
• Inner protective insert to prevent ceramic damage and retain the plug
• Suitable for use with standard drive tools for torque application
• Compact length for access in confined engine compartments
• Durable metal construction suitable for repeated workshop use

How to use

Select a compatible drive tool and attach it to the spark plug socket. Before loosening a spark plug, ensure the engine is cool to avoid damage to the plug or socket. Engage the socket fully over the spark plug hex so the internal insert grips the plug. Turn the drive tool counterclockwise to loosen and remove the plug; when installing, thread the plug by hand initially to avoid cross-threading, then use the socket and drive tool to seat and torque the plug according to the vehicle manufacturer's specification.

Usage recommendations

Use the spark plug socket only with compatible drive tools and observe recommended torque values for specific spark plugs. Inspect the internal insert regularly for wear and replace the socket if the insert no longer secures the plug reliably. Avoid using impact tools or excessive force that could damage the socket or spark plug ceramic.
