I bought 4 of these to replace a couple of the older high flow barbs and they are fantastic. The O-ring capture seal keeps the O ring from herniating under uneven pressure or to my direct down force. I am replacing all of my barb with the asap!
The FB (Fat Boy) Fittings from Danger Den are now available in a 90 Degree Rotary version. The FB Fitting integrates an O-Ring capture to seal and can rotate during installation. It has a large ID bore for high flow and lower pressure drop compared to other fittings. Designed with a G 1/4 BSPP straight thread.
