Sealey Oil Drain Plug Master Thread Repair Set - VS661

This kit is designed for cars and light commercial vehicles with common metric oil drain plug threads, specifically M13 x 1.25, M13 x 1.5, M15 x 1.5, M17 x 1.5, M20 x 1.5, and M22 x 1.5mm.

The primary purpose is to repair stripped or damaged oil drain plug threads on the oil pan, gearbox, or differential, allowing the use of a new, slightly larger drain plug.

Yes, the kit includes new drain plugs and washers that correspond to the thread sizes it repairs.

You should match the tap size to the damaged thread's original metric pitch (e.g., if the original thread was M15 x 1.5, you would use the M15 x 1.5 tap).

Yes, this kit can be used on aluminum oil pans, but extra care should be taken due to the softer nature of aluminum. Ensure the tap is straight and avoid over-tightening the new drain plug.

The kit weighs approximately 2.2kg.

Yes, it is highly recommended to use a suitable cutting fluid or oil when tapping. This lubricates the tap, reduces friction, helps clear metal chips, and prolongs the life of the tap.

Ensure you are using adequate cutting fluid. Make sure the tap is straight and not cross-threading. Back the tap out slightly more frequently to clear chips. Verify you are using the correct tap size for the thread pitch.

Ensure the correct size and type of washer is used. Check that the tapped thread is clean and free of debris. Verify the drain plug is tightened to the correct torque specification.

This kit covers the most popular metric sizes. If a specific, less common thread size is required, it may not be present in this set.

Thoroughly clean the tapped area with a clean rag and degreaser after tapping. Use a magnet to help remove any remaining fine metal particles. Consider flushing the oil system after the repair.
