We stock this fitting to terminate the EVA Barrier beverage tubing to any male flare (1/4"MFL) such as on a black ball lock beverage QD. Push the tubing all the way to lock it and seal it and that's it. Push on the sleeve to release. The secondary picture shows it threaded on to a Black Ball Lock QD, which is not included. Note that these fittings do not need flare washers or gaskets since the plastic is soft enough to create a seal.
IT IS VERY IMPORTANT that you do not overtighten these fittings onto the male flare counterpart or they WILL crack at some point. Follow these instructions. Put a small smear of keg lube or Vaseline on the threads and tapered tip of the male flare fitting. Thread the grey fitting on carefully to avoid cross threading and tighten only hand tight plus another 1/8th of turn with a wrench. 99% of these will seal without any additional attention.. Pressurize the system and to check for leaks. Any fitting that leaks should be tighten another 1/8th of a turn to stop the leak.
These fittings accept any rigid or semi-rigid 8mm or 5/16" OD tubing. Bevseal Ultra 235, EVAbarrier 8mm or any copper, polyethylene. To secure to SS tubing, you will have to put a small embossed ring near the end of the tubing by lightly running a tubing cutter wheel around it. This gives the locking claws something to grab onto.
