I want to replace two O-rings between pump unit and heater housing. This is a very common part on many Eberspacher / Espar Hydronic Heaters. I found one place to purchase it on line and it is not Amazon, it is Heatso from UK. Found a lot Eberspacher replacement parts in Aliexpress but not O-rings. Unbelievable.

#25 2 x O-Rings 14mm x 2.6mm - 22 1000 70 00 06 for $10 each (gold equivalent in weight would be $6),

Expensive day at Costco today, almost $1000 for new rubber and sensors. I decided to go with Michelin - Agilis CrossClimate LT245/75R16/E. Very quiet on highway, good on corners, van going very straight with hand off. Took just a few miles to reset new TPMS Dill sensors after they programmed them in with new IDs. Time will tell how good the tires will be in wet or icy conditions.
