I was thiks since one of the biggest killers of rotarys is heat which leads to coolant seal faliure. I was looking at parts for piston engines and thought if they have a metal head gasket which is suppose to seal better and last longer. Why not have some company try to design or research a soft metal compound ring that can be used for cooland seals. please give me feed back ppl

Last time I heard it was $300+ EACH seal.

Already been done, Its not cost effective. These seals ended up costing ~$140 from the manufacturer. Ordering 100 lowered the price to ~ 110 each. The market in rotary engines just cant absorb those kind of costs.

 

a bit of Historical info:

The MFG. I used was also approached by MAZDA in the early 70's about seals, the company made them some seals that worked well, but were also too expensive. I talked with the original engineer on the project.

 

Out of curiosity what was the out come of the seals? Did you conduct any testing of them?

 

I have a set in my P-Port. The pressure testing of them was successful. Durability and heat cycle testing has not been completed as of this time. Frankly its not a concern since I have no plans of marketing these actively. It was an interesting expensive experiment.

 

yhmm you souldn donate some seals to me and I'll put them through heavey testing

 

haha, me too?

 

but the question, is would they be reusable, and last forever??? if that was soo they may be worth the money, just curiousty of these things

 

$140 each? or for all of them?
for all it could be worth the extra..

when someone invents a cheap indestructo apex seal made of Ubertonium then we'll all be set for life.
