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.
  • 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.

BEST ANSWER: No, it is not compatible with duotight. The barbed end only works with tubing.
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.

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.

Duotight Installation
These work fantastic on Duotight compatible shank tail piece and other fittings such as the ball lock carbonation cap FE133. When installing it takes a very firm push, and you should hear and feel the click as the Duotight barbs engage the scribed line.

Works with Blichmann Beer Gun
I've used this connection to connect my beer line running to my tap straight to the liquid tube of my Blichmann Beer Gun! Though I can still yank it off with some force, the connection is 'beer-tight' as I bottle beer from my standard keg beer line.
