This Duotight to Female Beer Thread fitting is perfect for connecting gas line to keg couplers. Although it could be used with 9.5 mm EVA Barrier as a beverage line, this would only be recommended for long draw systems where the beverage line will be 20-25 ft long. Compatible with EVABarrier 9.5 mm OD tubing. It offers superior quality when compared to other push-in fittings. Their double EPDM O-ring design provides a more complete and reliable seal, protecting against leaks even when tubing is bent around tight corners. They are suitable for both beverage and gas applications, and are pressure rated to 100 psi. Tubing can be released by simply pushing in the collet and pulling the line out. No need for clamps or cutting lines!
