Description

This Duotight fitting with 1/4" Flare is perfect for flared gas and beverage ball lock and pin lock disconnects. It can also be used to connect gas line to the flare fitting found on the KOMOS® CO2 Regulator. Compatible with EVABarrier 8 mm OD Tubing (D1717 & D1718).
 
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.
 
 
Features:
  • 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.

Ball lock fitting and regulator not included.

Instead of trying to mate this BSP fitting to a NPT fitting, shouldn't we just get the H853, which is actually NPT? Then a regular DUO106 should screw right on the male flare from the H853? I'm suspicious of trying to use a BSP male in an NPT female.

Do these fittings work with any tubing or do I have to "retube" my kegarator with the EVA tubing?
Clifton Shoemaker on Jul 10, 2019
BEST ANSWER: You would need tube inserts to use these fittings on soft vinyl tubing.
I see how this attaches to tubing. How does it attach to the ball lock keg fitting?
david semo on Sep 23, 2019
BEST ANSWER: It has a 1/4” (female threaded) flare fitting that screws onto the quick connect. If your ball lock quick connects have barbs instead of threads it won’t work as you have the wrong kind.
I bought a 4 way manifold, 4mm evabarrier and duotight fittings and realized the fittings nor the tubing will fit the manifold. Is there any way or part that I can get to work around this?

BEST ANSWER: They sell a male thread to female hose duotight. I use them on my regulator and they work fine.
Anyone have any luck converting the barb gas outs to 1/4 flare on the Elite Series Four Product Secondary Regulator with this adaptor? If converted, then would work perfectly with a duotight DUO106

BEST ANSWER: I made the change over one year ago and everything has worked great. Make sure you also replace the existing plastic gas line with new duotight plastic gas line. In my case, I added duotight fittings and plastic lines for both the gas in and beer out.

Just tested it out the other day, I really like this so far, hoping it holds up, simple connecting that hasn't leaked and holds.

Use these all over the place
Must use nylon flared waher with metal flare (i.e. when not on keg adapter) or you will have a leak. They can fail when over tightened. Now that I know the pitfalls, I still use them everywhere for gas fittings.

Basically fool proof
Super easy to install, allows me to swap my CO2 tank between gas to liquid disconnects in seconds.

Ruined the threads on one by cross-threading - if you feel resistance while screwing them on before they're fully seated, remove it and rethread.

Finger Tight Plus 1/4 Turn, Any More Will Wreck The Fitting
Disappointed with the installation instructions... that say finger tight plus 180º (1/2 turn) more. I did exactly that with a quality CM Becker ball lock but found it distorted the Duotight and pulled the plastic threads. I ruined one fitting by exactly following those instructions... Subsequently, I found the ideal torque is finger tight plus 90º (1/4 turn) more. That seals properly, keeps the fitting intact, and it doesn't back off the threads... Five stars for the part - Zero stars for the installation instructions.
