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.

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.
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.
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.

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

Duotight fittings
These fittings are awesome. Easy Peasy.... I changed-out all my plumbing to this and it now the kegerator pours beautifully.

I changed everything to duotight with a 10ft hose on each valve. I say, 10' hose and 10psi for pressurizing the kegs. It worked beautifully for both lagers and IPAs.

I replaced the tower on my kegerator and decided to try the Duotight fittings. Super simple to put it together and ended up buying all of the parts to do the CO2 side as well.

work, but break easily
these work great, IF you have them on correctly. It is very easy to over tighten, and snap the fitting in half, just using your fingers. I finger tightened three of them to cracking point before I realized it was the design of the unit, and not a faulty set I'd gotten. Again, they work, just be careful tightening.
