Socket for Spark Plugs Proxxon PR23553 14 mm 3/8" Drive

Proxxon PR23553 is a 14 mm socket for spark plugs designed for use with 3/8" drive tools. It is shaped for a snug fit on standard 14 mm spark plugs and intended for removal and installation tasks on automotive and small-engine applications. The socket combines the correct internal profile and length to reach spark plugs recessed in engine heads while remaining compatible with common 3/8" ratchets and extensions.

Advantages

The Proxxon 14 mm spark plug socket offers a precise fit to reduce slippage and protect the ceramic insulator of the plug. Manufactured with materials suitable for workshop use, the socket maintains dimensional accuracy for repeated operations. Its 3/8" drive interface ensures compatibility with a wide range of hand tools, enabling safe torque transfer and straightforward connection to extensions or universal joints.

Suitable for

• Removing and installing 14 mm spark plugs in cars and motorcycles
• Servicing small engines such as lawn mowers, generators, and scooters
• Use with 3/8" drive ratchets, extensions, and swivel joints
• Professional mechanic workshops and DIY maintenance

Key specifications

• Sanded socket diameter: 14 mm
• Drive size: 3/8" (9.5 mm) square drive

How to use

Attach the Proxxon 14 mm spark plug socket to a 3/8" drive ratchet or extension. Ensure the engine is cool before attempting to remove spark plugs. Fit the socket over the spark plug hex and turn counterclockwise to loosen; use steady, controlled force to avoid damaging the plug. For installation, thread the new plug by hand to avoid cross-threading, then tighten with the socket to the manufacturer's recommended torque using a torque wrench or a calibrated feel with the ratchet.

Usage recommendations

For best results, inspect the spark plug and plug well for debris before removal, use an extension or swivel joint when plugs are recessed or at an angle, and avoid over-torquing when installing new plugs. Store the socket in a dry toolbox to prevent corrosion.
