Duotight Push-In Fittings – 8mm & 9.5mm for Flare Connections

Tool-Free, Leak-Free Connections for EVABarrier Tubing and Flare Fittings

These Duotight Push-In Fittings are available in 8 mm (5/16") and 9.5 mm (3/8") push-in sizes, each with a 1/4" Flare (male) thread on the other end. Perfect for connecting to flared ball lock and pin lock disconnects, as well as regulators like the KOMOS® CO₂ Regulator. Choose your desired push-in size before adding to cart—each option pairs with the correct size EVABarrier tubing to ensure a tight, reliable seal with no clamps required.

Duotight fittings feature a double EPDM O-ring design that delivers superior sealing performance, even around tight bends or under pressure. Rated for both gas and beverage lines up to 150 PSI, they are an ideal upgrade for draft systems, kegging setups, and CO₂ distribution networks.
