Description

This Duotight fitting with 1/4" male thread is a great option for connecting gas line to regulators and manifolds that have 1/4" FPT. Comes with seated O-ring. 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.
 
 
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.

1/4" BPS (19 TPI) isn't the same as 1/4" NPT (18 TPI). Will they still create an effective coupling? Will gas leak at something less than the rated 150 psi?
David Napack on Mar 27, 2020
BEST ANSWER: These fittings will still create an effective seal. The included o-ring gives and extra sense of security when using higher pressure applications.
Will this work with the Taprite 1060 Regulator?
Paul Adair on Apr 18, 2019
BEST ANSWER: Hi Paul - As long as the regulator has 1/4" FPT, it will be compatible.
