In preparation for purchasing my first set of Tap-a-Draft bottles, I scoured the web for ideas on how to use bottled CO2 with the bottles. I saw several ideas, but didn't like the price tags (~$50). Why not just buy kegs at that point? So... after some research, and 3-day shipping from US plastics, here's my take:
I used the following items from US Plastic:
One 1/8" check valve (Item #57171, $2.01)
Two 1/4" HDPE elbows (Item #64904, $0.71 ea)
(didn't use the 1/8" elbows, but with $7 shipping & handling, I got them just in case)
Shipping: $5.99 (most expensive part)
Here's the basic process I followed:
1) drilled two 5/16" holes in the top of the Bottle caps (after removing the cap's interior post with an Exacto knife). cleaned up holes
2) used superglue to hold elbows in place with a small (~3mm?) offset from the fully seated position to give clearance when installing the exterior tubing.
3) JB welded the underside of the caps around the elbows
4) removed hot glue, & epoxied all around the exterior of the elbows
5) "glued" check valve in place using tile/tub silicone caulk. Yes...there are a faction of you cringing at this...feel free to be fancy & use stainless, but we all pay our own bills.
6) installed ~1.5 ft of beer tubing & a party tap to finish the job.
7) I will add a length of vinyl tubing to the fluid out barb & weight the end down with a SS nut (~$1?)
Initial pressure test was ~10PSI induced via a bicycle pump. Held pressure great & no leaks!
