The attachment below is our technical specification paper on the "Deep & Altus Pursuit" solenoid.

Beautifully made and with a very professional clean clear and concise data sheet. This will do well, I guess 6000 ADP rebreathers times 2? LOL.

I have one small question, as I don’t understand you fully on the lubrication.
Although as I speed read, I first read it as “Do not lubricate (with) any other lubricant and not “Do not lubricate any other component.” You do say strongly use only Fomblin18.

On one hand the 0-rings you specified are fluorocarbon and I can see this for low temp flow and pressure drop performance (in a dynamic condition) etc. However you specify only Fomblin18 as the only lubricant allowed. Yet the rings are in static condition, Why?

With your fluorocarbon polymer choice I would have thought that the standard scuba Christo-lube MCG III would have been your preferred choice, also most divers and dive shops (I guess) use it. I’m just intrigued why Fomblin 18 and no other lubricant. iain
