I believe that valve is similar to the saddle valve. Here is the least expensive, great working one:

Well after I posted, I got a burnt taste. I took the carto off, and was playing with a 2.5 ohm dual coil for a while. Well, I put the Renew back on, and forgot to turn the voltage down, and really burnt the crap out of it. I tossed it, and slowly filled a new one. I also turned my PV down to 3.3 volts, and took a few hits, then topped off and slowly added voltage. Just to be sure. I believe part of initial burnt taste was me not quite filling it enough, and hitting it with 8 watts right off the bat. Anyhow, the 3rd one has been fine all day long now...
