Here's a pic of my polypropylene tank

[craftmath]

And if this is the case, with the nylon washer having NO give, I plan to dremel the hole so that the cartomizer is snug, and then placing a grove in the OD of the washer for an oring to fit nicely in. Fingers crossed that it works. I like the grommets, but I would be much happier with an endcap similar to what most sale with their tanks. WHERE DO THEY GET THEM FROM!!!???!!!???

Hmm, I doubt there will be much, if any, give in that nylon, but we'll see how it works out for you.

Nylon 6/6 Shoulder Washer, 0.310" ID, 0.500" OD, 0.190" Thick, 0.750" Shoulder Diameter, 0.44" Length (Pack of 50) | SmallParts.com

The only thing I'm not sure of his how much "give" the washer will have being that its nylon. If there is NO give, the cartomizer will not fit and the OD of the washer will not expand to fit tightly with the ID of the polytubing.

I'd like to know where they get them from myself.

As the op of this thread, I had the same concerns about a nylon washer, being that there is no flexibility for an acceptable seal. I went ahead and ran a coop for the new polypropylene DCTanks, and now I'm done with fiddling around on this. I have as many tanks as I'll ever need, and I'm happy.

Aww c'mon, can't have too many tanks. Just gotta buy more pv's to put them on.

I'll be making a trip to all the local hardware stores, see what I can't come up with, anyone look into using glass tubes?

I love all the brainpower we can generate as a collective

Through all of your great ideas, I made myself a really nice tank. I find myself in a similar situation as my4jewels was in before she scored a bunch on a coop, I at least want a dozen tanks for all my DIY flavors. It's nice to be able to pick a different tank and flavor to take to work every day. I followed the link to McMaster to get the tubing, and since they are like a toy store to someone like me, I browsed the site for a while. I found some high temp silicon grommets that looked like they would work, so I got 'em... and they worked. My thoughts were that silicone should neither degrade nor affect flavor, nor leach chemicals into the nicjuice. They're also orange/red for a little color. Link- McMaster-Carr I got some o rings for my existing tanks and more o rings for drip tips (those are backordered currently....I bet our vendors have been here too!) I finished it off with a fill port and a computer case screw for a plug. I can put in a flat computer screw of the same thread type if I want to make it smooth and sleek. The fill port is almost a must, these grommets are really tight when in the tube. I was afraid they wouldn't seal around the carto, but when squeezed into the tubing they compress around it. It was tricky getting them in with the carto just right, but they aren't going to slide or leak. No o rings needed, except of course on the drip tip.

Nice looking tank, Bourbonman.

 

[familiarstranger]

Can you post part numbers for your supplies? I'm having trouble locating the right size grommet on McMaster-Carr

I feel like an idiot, I can't even find clear/frosted polyprop pipe on McMaster.

 

[Bourbonman]

The grommets I used were part #1061T83
The tubing was part #5392K17

I put a socket (from a socket wrench set) inside the tubing and just used a regular plumbing pipe cutter to cut lengths off. It gives a pretty nice cut edge, I sanded the first one, and it didn't really look better enough to be worth it. I just cut the rest and used them.

 

[Bourbonman]

Oh, and the polypropylene tubing will have a curve to it, don't worry, it doesn't affect the tanks at all.

Here is what you need

 

[Dracconus]

For those of you who are wondering about the polypropylene tubing I've been using to replace my polycarbonate tubing on my tanks, I thought I'd post a pic for you.

This one uses a couple of liquinator caps. This tubing will fit on all of the popular tanks that use a 5/8" x 3/4" od tubing.

Have you ever thought about using Tygon PVC? It's what we used when I worked in the food industry for HUNDREDS of different things. Every commercial coffee/icecream machine in the world uses one pretty much. Holds up well over time, non-imparting, and prevents bacterial growth, plus you can autoclave it in gas, or steam.

I was poking around richco for grommets etc and look what I found....

Grommets, Plastic Grommets, and Bushings from Richco - BP - Body Plug, Flexible

and

Grommets, Plastic Grommets, and Bushings from Richco - LTG - Grommet,Liquid Tight

I'm contemplating grabbin some samples of these and seeing what i can do with them.


This is grommet heaven as well:

[sportyfortyeight]

I was lookin at the tygon and it seems it might work well and comes clear but SO many types. Not sure what grade would be best for what we would use it for.

Edit.. after looking into it some it seems 2375 would work but I'm not a plastic expert. It is a bit more expensive but is also clear... Any thoughts for using it for tanks

I haven't tried the polypro route, but here are my "syringe tanks".
