60 day no hassle return policy. Details

This Duotight to Female Beer Thread fitting can be used to connect beverage line to faucet shanks instead of a tailpiece, and it's also a convenient option for connecting gas and beverage line to the gas in and bev out on keg couplers. Compatible with EVABarrier 8 mm OD Tubing (D1717 & D1718).
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.

Faucet shank and keg coupler not included.

Can this be used with a 2" shank in a draft tower? The current shanks are the Intertap ones with permanent 90 degree barbs and I am hoping to convert entirely to the Duotight fittings.

BEST ANSWER: The threads on the 2'' shank are 5/8'' BSP threads so the DUO104 unfortunately will not be compatible. However, we will be offering the short tower shanks that have Duotight compatible barbs very soon!
i have this tubing, will it fit with this? Accuflex Bev-Seal Ultra beer line. 3/16' ID
Tom H on Mar 27, 2020
BEST ANSWER: I am personally unfamiliar with the tubing you’re going to use. If the OD is 5/16” and you have a straight cut, push your tubing in until it totally stops. Run a leak test using water. If you need to remove the tubing, the Duotight fitting will release with pressure applied to the circular collar where the tubing is inserted and a firm pull on the tubing. If the duotight fitting on your particular tubing leaks, I recommend what I use and got on on this website, EVABarrier 8mm tubing, D1717 or D1718.
I want to use these in my keezer build. what size shanks should I buy to go through 2x4 leaving enough room to connect these?
John Fitt on May 12, 2020
BEST ANSWER: If you are going through the 2" side of the board then you will be fine with using the 3.5 or 4 inch shank. There will be plenty of space for the lock nut and the tube fitting.
Will this duotight fitting fit this shank? https://www.morebeer.com/products/beer-faucet-shank-5.html Also, do you know when this will be back in stock?
Adam Lund on Jun 25, 2020
BEST ANSWER: This is the correct duotight fitting for beer shanks as well as sanke keg couplers commonly referred to as "Beer Thread".

This is all you need for Intertap faucets if using Duotight fittings.
If you are using Intertap faucets and EVABarrier tubing - this is all you need to source a new tap. I would recommend using the 4mm EVABarrier tubing for product lines (more resistance).

One caveat - my experience is this ONLY WORKS with INTERTAP stuff. It MAY work with Nukatap...when I tried it, it absolutely would not seal correctly with a Kroma tap. It has little keyway cuts that Intertap faucets work with. Bonus, it comes with the seals and Duotight fitting, back nut and front flange...all you need is the faucet and EVABarrier tubing, plus the matching Duotight FFL connector and a cornelius connector for the product line.

No Hose Clamps
I was nervous about trying these, but for the price point, decided to go with them. Easy to install right out of the box, and works flawlessly.

I was not thorough in the first order of these, and missed a couple of needed components. Recommend being more careful to get everything needed (in the correct size) the first time.

Great if used correctly
These work really well with the EVA-barrier tubing, if you push the tubing in all the way, It took a while to figure out how to remove the tubing (the same way you get your fingers out of a Chinese finger trap).

Easy to connect.
Screw this on, plug your tubing in and you are done. Nothing could be simpler. I only wish this was available when I first built my keg system as it is very clean and easy.
