This Duotight elbow fitting is 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.

Zach R on Aug 21, 2021
Evabarrier tubing is fairly stiff and you don't want to place too much stress on your Duotight connections. This should allow me to make tighter gas tubing turns within my keezer.

looking for a duotight fitting for the temp twister cooler ...any answers?
Mark Rader on Jul 3, 2020
BEST ANSWER: The temp twister is OD 3/8 or 9.5 mm so these are too small to attach directly. Either get the 9.5 mm elbow (DUO112) and 9.5 mm tubing or the 9.5 mm to 8 mm (DUO105) and then use this fitting and 8 mm tubing.
