At 40psi I would get a better check valve like brass, they due make some plastic check valves that are made for co2 also. You can fine these check valves sold here in the power sellers or on ebay, or best bet yet http://greenleafaquariums.com/co2-resistant-tubing.html
For your bubble counter I use mineral oil and fill only half way , I have not replace mine for a year yet.
