Description

This Duotight reducer fitting can be attached to the Intertap Short Shank with 1/4" Duotight compatible barb (D1242). Compatible with EVABarrier 8 mm OD Tubing (D1717 & D1718). Also attaches to the Plastic Ball Lock Cap, allowing the cap to be used with 8 mm OD EVABarrier.
 
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.

Would this connection work on the liquid tube of the Blichmann Beer Gun?
Michael Dat Nguyen on Dec 22, 2019
BEST ANSWER: Hi Michael, we recommend using EVABarrier 8 mm OD Tubing with this fitting.
Is this barb compatible with the Duotight system fittings, specifically the Duotight Push-In Fitting - 6.5 mm (1/4 in.) x 8 mm (5/16 in.) Reducer?

BEST ANSWER: Hi, I mistakenly asked a separate question, but is there a unit like this that does connect to a PTC adapter for a liquid line?
Does this work with any shank? Or does it have to be duo tight shank
jeff kiefer on Nov 7, 2022
BEST ANSWER: I used it on a barb style shank, but I cut off the barbed section with a dremel first. After cutting, there was just enough straight length left to use the duotight adapter. YMMV, but mine's been working fine for years.
Does this connection work on a smooth stainless steel 1/4” beer tower or does it need a groove to keep from sliding off?
Kevin Allyn on Oct 22, 2022
BEST ANSWER: I think this should work on a smooth fitting as the dual o-rings inside the fitting provide some pressure against the tubing, but the internal metal barbs may not be as effective for holding it on as they would be if there was a groove.

DuoTight Reducer
I have found a multitude of uses for these reducers. They essentially convert 1/4-inch tubing to 8mm EVAbarrier tubing. For example, I used them to convert my WilliamsWarn Counter Pressure Bottle Filler to 8mm DuoTight and EVAbarrier.

Came loose at a critical moment
It came loose, and it was a pain in the neck to set up in the first place. It sprayed beer everywhere inside my kegerator. Now, I have to reattach it. Clever idea, and hopefully it will work right the second time.

Work well when you need a reducer
Does what is supposed to do. Hold on to the faucet shank stem as well as the Kegland style plastic ball lock stems. Used the ball lock stems on the back of the Komos kegerator for gas.

Super useful for KegLand's counter pressure bottle filler
I bought some of these for my new KegLand counter pressure bottle filler and couldn't be happier. They attached easily and haven't leaked even after detaching & reattaching them several times.

Possibly wrong size
This seems like it will be a good product and I plan to switch my connections to duotight. However, the product that was sent along with my EVA 8 mm OD tubing that II ordered did not fit. It did fit on the shank properly, but was much too large on the other end for the EVA tubing that was in the same order. I suspect that I was sent the wrong size connecter because both the product description and the EVA tubing description state that this should work. I ended up using stepless clamps this time, but do plan to switch.

Works as advertised
This connects the Intertap faucets to the EVA 4mm lines. This is basically a reducer to run the EVA lines. It works as advertised but make sure you buy a extra because if you make a mistake and have to pull the adapter out, the prongs break easily. It's cheap enough to have extras laying around just in case.
