The Keg King MKII is a high quality regulator at a great price. Features a large body with precision diaphragm for large flow rates when needed. Does not experience creep like many generic, cheaper chinese regulators.
The MKIII has a second sintered filter on the underside of the seat cap assembly to help prevent the contamination that can cause a regulator to not work properly. Also the seat cap assembly is fully enclosed to reduce the chance of contamination if the regulator is opened for serviced
The seat and seat cap assembly are made of ultra-high molecular weight polyethylene (UHMWPE) gasket. UHMWPE is much better than the normal Teflon gaskets.
