Re: Legal Pneumatic Fittings - Nipples & Elbows?

I read the flow specification on the valve as without fittings for the exhaust ports. So a 1/8" port with no fittings ought to have a higher flow rate than the same port with fittings inserted.

well, this still strikes me as a "1080p" TV sold with only an s-video input.

thanks for the info on the Cv of tubing and fittings, based on reading CD threads about flow restriction, I had assumed past KOP solenoids were significantly* worse than tubing and fittings, but I guess not...

*maybe a Cv difference of at least 0.1, as opposed to 0.03

Re: Legal Pneumatic Fittings - Nipples & Elbows?

Going back to the OP's question, I would suggest testing your setup with a nipple, and with the tubing. See if there is enough difference, or even good difference that would be worth risking the creation of a new rule.

One of our mentors had the same thought, and attached one of our higher Cv solenoids to an accumulator with a short brass nipple. Imagine our surprise, when the increased "performance" turned out to be detrimental to the actual performance of our catapult. Everything was promptly changed back.

Test your theory, and find out if you are just tilting at windmills with trying something that will attract attention from inspectors. You will at least satisfy your curiosity, and you may just find, as we did, that it isn't worth it.
