This Duotight fitting with 1/4" Flare is perfect for flared gas ball lock and pin lock disconnects. Can also be used to connect gas line to the flare fitting found on the KOMOS® CO2 Regulator. Compatible with EVABarrier 9.5 mm OD tubing (D1719). Although this fitting would also fit a beverage disconnect, 9.5 mm OD EVABarrier is only recommended for beverage line in long draw draft set ups.

The Duotight fitting does not require a flare washer. See the instructions below for how to ensure a leak-free connection when attaching to flare fittings.

Duotight fittings are high-quality push-in fittings that seal tight and offer superior sealing capacity due to the double O-ring sealing design.
High Performance Double O-Ring Design:
The secret to Duotight’s superior sealing performance comes from the fact that they use not one, but two high-quality EPDM O-rings.  The double O-ring means they have literally twice the sealing surface when compared with other push-in fittings.  This makes them more reliable and significantly reduces the chance of leakage.
The double O-ring system also means that tubing can be bent at a much tighter radius without causing leaking issues, which can be an issue with other fittings.  This combination of factors makes Duotight the most reliable push-in fittings on the market.
EPDM offers excellent chemical resistance for a longer life span. When compared with silicone and vinyl, EPDM has much better gas transmission rates, better wear resistance, and is BPA-free.
No Clamps Necessary!
We recommend cutting your tubing straight, not on an angle, to ensure the line forms a complete seal. To remove the fitting simply push in the collet and the hose can be removed.
  • Insert tubing and firmly push to connect
  • Easily release tubing by pushing in the collet
  • Suitable for both gas & beverage applications
  • Made from food-grade acetal plastic
  • Double O-rings made from highly chemical resistant EPDM
  • Locking teeth made from stainless steel
  • Pressure rated to 150 psi
  • Temperature rated to 212°F (100°C)

Please note: exposure to chlorine will degrade the acetal plastic and stainless steel these fittings are made from. Do not use in contact with bleach or other chlorinated cleaning chemicals.

maybe a dumb question, why is the secondary regulator 8mm but this is 9.5? Don't they directly connect?
Scherzinger Andy on Dec 23, 2020
BEST ANSWER: 9.5mm is meant for liquid side, for almost every application it will suffice to use 8mm for gas side. 9.5mm liquid is good to 1:1 replace standard 3/8” hose… only with the benefits of Evabarrier

Great for both gas and beer
I use these on all gas and beer lines. Be careful not to over-tighten or they will crack. Quick release makes cleaning very easy.

Purchased these to use in rebuild of CO2 delivery system. They are simple, and eliminate barbed connections that have been problematic.

These things are legit. Switched my kegerator over to duotight for gas and liquid connections.

Love using these on my draft systems.
Switched all my gas and beer lines over to using the Duotight fittings. Really important to get a nice clean / square cut on the hoses with no burrs on the hose lines in order to prevent leaking. No more needing a flat head screwdriver to remove hose clamps when changing lines and no more slicing your hands on the hose clamps.

Good in theory...
I bought these with the hope that they would be easy to disassemble and reassemble but that didn't pan out. They don't come apart at all and one broke as I tried. This was a costly experiment that failed completely. Nice system if you never want to take it apart.
