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.

My father purchased an O2 kit me for Christmas. It cam with 2 duotight fittings for the flow meter but the regulator has a barb fitting. To make the EVA tubing fit the regulator there should be a third duotight in the kit.

Alastair B P on Mar 2, 2023
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.

BEST ANSWER: That’s my same question.
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?

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.
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.
Are these fittings rated to sub-freezing temperatures?
Peter Kraemer on Apr 27, 2023
BEST ANSWER: Probably not sub zero but would probably work for glycol systems near 0C/ 32F. Maybe contact the manufacturer directly.
Has anyone had success finding these in stainless steel? These are great but are plastic and break easily.
Marc Laroze on Dec 30, 2021
BEST ANSWER: Yes, they're available as SS "push in fittings" ; however, they are very expensive. If you're looking for better quality at a cheaper price try John Guest fittings.
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.

If you keg and use flares you will likely need this.
In expensive, works well with the correct tubing. No leaks and not exactly easy to remove but can be removed. This was a no brainer. I did make a CO2 distro system with this, into an inexpensive kitchen refrigerator with the tank and distro system in the fridge. Doing this takes planning, organization and space in the fridge or you will find yourself unhappy with the results. it works but probably not like you though it would unless you plan it out carefully. The same for a multi keg, kegerator..

Weak Threads and Gas Leaks
The guidelines say to tighten with your fingers and then go another 90 degrees. This is flat-out wrong. Gas will escape.

You have to tighten these things way past finger-tight plus 90 degrees, and because the plastic is soft, it's very easy to strip the threads. You have to know exactly how far to tighten then, and you learn that by destroying one or two.

Fell apart
I was using one of these in a CO2 line set at 10 psi when one night it literally fell apart. I lost a full cylinder of gas. I really could not believe how it just separated.

Used to connect to H853>Taprite regulator
Had to tighten more than directions said to. Finger tight, then used wrench until resistance felt, then another 1/2 turn. Used soapy water test to verify seal. Duotight system held pressure for more than a week before I discontinued test.

Duotight
Not a good use on regulator with brass fitting.
you need the insert and it's hard to get in.
will change to Duo with 1/4 NPT to go into regulator
next time. Love Duoptight completely change on all my gas and fluid line to Duotight
PS, now come up with a Duotight Cap

I have both pin locks and ball lock kegs so it easy just to change the 1/4" fitting with the 8 mm tube so I put them on the connectors and just change the to a different connector by plugging or plugging the tubing

They are the best!
I really like the versatility of the quick connect. Tighten them down on your regulator and never have to remove them.
