        time and effort saver!

        In the past I used the barbed gas/beverage ball lock connects for my kegs. I recently switched to threaded (flared). Using these (item # KEG640) as the female end on the gas tubing makes it so much faster and easier when filling a keg. I can hook the beverage ball lock connect to the gas tube to purge the keg so much easier now! I highly recommend!

        Nice for gas tubing

        Versatile and leak free. These are great!

        No more cutting tubing

        Like a poor man's quick disconnect. These works great when you want to unscrew your tube from a ball lock versus removing a clamp and cutting the tubing. Easy to install and clean too. My whole system is using these now.

        Does this work with the stainless steel quick disconnect I just bought here at More Beer? Thx.

        MoreWine

        If you are referring to the Torpedo Ball Lock Quick Disconnect or similar item yes it works.

        MoreWine

        If it has a 1/4" male threaded connector it would work.

        MoreWine

        This is for connecting a 5/16 (ID) hose to a Ball Lock fitting. Not your typical quick disconnect. There is a difference.

        For the barb used in this set does the recommended tubing size of 5/16" refer to the ID or OD of the tube? Which item# would you recommend for the tubing?

        MoreWine

        Inner diameter

        MoreWine

        It refers to a 5/16" inner diameter. There are a variety of options that will work all with their respective advantages. You can find them all on our website typing "5/16" into the search bar. The antimicrobial tubing is my favorite for a home kegerator.

        Here comes a dumb one so brace yourself... can I (or should I) silver solder a stainless steel pipe onto this?

        MoreWine

        Hi Eric - I'm not sure what the exact application would be to solder a SS pipe onto the flare fitting. Would it be possible to explain a bit further?

        Will your Flare Fitting - 1/4 in. Swivel Nut (Stainless Steel) work with the 5/16 barb this setup comes with?

        MoreWine

        Hi Jason - Surprisingly these will NOT fit together. KEG601 is designed for a 1/4" barb.

        Do I need to purchase a flare fitting washer with this set?

        MoreWine

        Hi so the flare fitting is threaded to screw the 1/4" Nut & 5/16 Barb onto between a barrier (metal?)

        MoreWine

        You need a flare fitting washer for every flare connection you make. Also get lots of extras since they're tiny and easy to lose in a drain etc.

        MoreWine

        Only if you are connecting metal to metal - such as a male flare on a manifold or regulator. If you are using it to connect to a beer or gas ball lock quick disconnect then those disconnects have a bit of plastic built in and you don't need to use the nylon flare washer.

        MoreWine

        I would recommend purchasing the fitting as an extra protection from losing CO2. Very frustrating when everything is hooked up and you are losing gas that this fitting might prevent.
