Kegland’s DuoTight Fittings are designed to work with EVABarrier Double Wall Tubing. They offer quick, reliable connections, easy implementation, a variety of fitting options and feature amazing versatility. They’re also, generally speaking, very well priced. DuoTights are push to connect fittings and require no tubing clamps.
DuoTights are… awesome. Check out my extensive Hands on Review
Valuebrew has DuoTight 8mm compatible fitting that converts DuoTight to 1/4″ barb. The product description says the fitting should work with most 3/16″ tubing as well.
These have been in and out of stock since they were introduced. And have been solidly out of stock for a long time. They’ve popped in stock and sold out quickly. The last time I can find a post on these on Homebrew Finds was back in July. Check product page to see if you can get in on these this time around.
Note: A number of add on options are available including DuoTight Compatible locking clips.
