The diaphragm is the only part of the MM-1 and MM-5 engines that wears out. The wear part is made from very thin (and hard to find) silicone rubber. When our engineer first tried to buy this material he spent three days on the phone. You might want to have a spare.

Good for DIY’ers

If you want to build a DIY coffee cup Stirling engine with a diaphragm that will last, then DIYers might also consider buying this part.

The easy to find alternatives to a silicone diaphragm like this are latex and vinyl (from latex or vinyl gloves). Unfortunately, those materials weather in the light and fail in a few weeks.
