I recently purchased EVA Barrier Beer Line and DuoTight disconnects.

But the problem arises when I am trying to do the closed transfer from my fermenter as it's tap is not compatible with the EVA Barrier.

Fermenter Tap is a barb type hence not sure how to connect with hose.

Please see the picturesenter image description here

You could replace the barb with something more suitable. One possibility: this 1/2" NPT to 1/4" flare adaptor, plus a swivel flare fitting such as this (EVAbarrier can be softened in hot water and pre-expanded with an awl, pliers, a pen cap to then fit over the swivel).
