The Ultra High Flow screw cap fuel stopper is unique on the market in many ways.
The stopper is entirely CNC cut on our high precision Sinumerik 804D milling machine to 4/100 mm.
We are using a certified Al 6061 T65 alloy that is ASTM B221 approved and quality traced.
The large stopper diameter allows the use of our Ultra High Flow medium or large clunks.
The inner barb is 3/16", 1/4" ID and 5/16" to accept our 3/16", 1/4", or 5/16" Viton fuel lines without restrictions.
Here are the specifications of the flange that needs to be glued on your tank with Hysol 9462.
