Ninja OFV Fill Nipple Assembly

IN THE USA!!!! This fill valve features an O-ring-style seal, which removes the need for any sort of thread sealing tape. The fill valve also utilizes a "shoulder" to prevent over-tightening and ensure proper pocket depth when installed in the regulator body. This fill valve can be found on all new Ninja regulators marked OFV above the fill port; it is not compatible with NPT threaded systems.
