Neptune DOS Modification
I really like the DOS pumps but wasn't thrilled with the tubing connections. I found that the threaded connection was 1/8" NPT therefore it was just a simple part exchange. The conical grey part of the fitting on the pump can be removed with a razor. I tried both ways and saw no difference in the push fittings ability to seal. (note: tubing does push in further if removed). Tubing removed from pump for photo. Modification can be done without dis-assembly.

Sweet!
I hate the so called "Flex" tubing that Neptune supplies. That stuff has a mind of it's own!

I may have to give this a shot. I was planning to do a john guest union just a few inches off the DOS. This is even cleaner. Thanks for sharing!

Nice! Looks clean. I use ro tubing and just heat it up a bit and push it up on the nipple.

He's using the stock tubing. This is actually a pretty interesting mod. I use 1/4" RODI type tubing & while I have no issues with the existing fittings, I much prefer the John Guest style push lock fittings & have everything I need for this mod. I might just have to do this myself.

Scott, I set up an auto feeder with my DOS using your wine cooler design and the Neptune stock tubing. I'm worried that if I do this mod and use the RO tubing (which is necessary for an airtight fit with the JG fitting, right?), the smaller i.d. of the RO will more easily clog. Am I right?
As an aside, my wine cooler fried from excess condensate getting into the motor when I used it on a four day trip. Has this happened to you?

I haven't had a condensation issue with mine and mine has been running 24/7 for several months now. What cooler are you using and have you figured out where the condensation was originating from? If it's coming from the area where the bottle sits, try sealing any seams with silicone or some sort of spray in plastic coating to seal it in.

I did the modification yesterdays. My DOS is used for AWC and I had leak on the side drawing water from the storage reservoir and had to use Teflon tape in order to get it to pump the water up. I am also getting periodic small air bubbles on the outlet side of both pumps but I am using the DOS supplied tubing on the discharge side and RO tubing on the inlet side.

Did you have to recalibrate your DOS after changing the tubing?

It is always a good idea to recalibrate after tubing changes. Friction loss due to tubing material differences and lengths will impact flow rates if even slightly. As such, recalibrating is a good idea to insure your fluid transfer amounts are as accurate as possible.

Where did you order these connectors? I am having a hard time finding the right ones.
Thanks

That said, I had to cut the tops off the Dos tube ends because they interfered with the 1/4" tubing and prevented it from going all the way into the JG fitting. Not a big deal and I just nipped the tips off with a scissor which allowed the JG fitting to thread all the way on. I also used Teflon paste to insure there was never going to be any leaks.
