Additional engine pencil anodes.
Manufacturers fit a variety of different bushes with
various threads on the outside to screw into the engine.

They also use different threads or a press fit to retain
the replacement anodes.
Some anodes are also shorter than usual because
there is not enough space inside the engine.

If your bush has a tapered pipe thread (NPT) without a washer it is likely
to take a standard anode with inexpensive die cast unc threads.
If your bush has a washer it will probably be metric and have a metric thread
on the anode. In this case we can supply anodes machined from rod stock The necessary information is the body diameter, the body length, the additional
length of thread and the thread description. ( for example 7/16" unf or 10mm)

The following list describes some of the anodes and bushes used by various manufacturers. It could help identify the part you need. Ask for advice if you
need to replace a pressed in anode.
