This Duotight fitting makes it easy to split your gas line and run it to multiple kegs. Use one tee for a dual tap kegerator or two tees for a triple tap. You can also pair the tee with the Push-In Pressure Gauge to use the gauge with the BlowTie Spunding Valve. 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

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.
