O rings will work in both models and stationary engines. I used to sell mechanical seals for a living and some of the guys here on the list remember when I had the old fashioned asbestos gasket material. Well nowadays I carry Garlock non asbestos material but that is another subject. There are 2 basic rubber compounds that are available to you. Buna N is the type that comes in the inexpensive commercial grade o ring kits where you get about 200 of the different sized o rings. This material is good to 210 degrees F. The other higher temp material is called Viton, it will get you up to 400. O rings take the shape of the groove they occupy and after awhile take a compression set. Basically if you put a round o ring in a square groove it will come out square and heat will harden it. Chemical attack makes them soft. I think a quad ring may work better in some applications, this is found in hydraulic cylinders and is basically a 4 sided o ring.  Do not use a material called ethyle!
 ne propylene (EP), petroleum lubricants will swell the material and your engine won't move. Hope this helps. Joe
