We have an older Speedaire air compressor, model # on the tank is 3Z243.
There are no parts available that we can find, under that specific model number.
Based on our best guess, using the tech specs from Grainger and their parts source,
a 5Z405 is the modern match to what we have. Do you think that the heads with
valve plates can be interchangeable? The part # we found is TF067301SJ. Ours has
old paper gaskets, these are set up for O-rings. The bolt pattern and dimensions seem
to match up.
The manufacturer has asked that you take a picture of the unit and the pump and post here so that I can send it to them. They can't find anything by your model number.
