The F3BH is the big bore of Ronco's bulkhead line: a 3 inch through-wall fitting for the connections where flow rate is the whole point - fast gravity drains, pump-out ports, transfer manifolds between large tanks. At this diameter a tank empties in minutes, which changes how you operate it: cleanouts become routine instead of an event.
Like its smaller siblings, it seals with a gasketed flange drawn tight through a drilled hole, and leaves standard 3 inch threads outside the tank wall. The flange at this size is substantial, so it wants a flat face of adequate area - plan its position on the tank before drilling, because a 3 inch hole is not a reversible decision. As Ronco's own hardware it is proportioned to the wall thickness of Ronco moldings.
Molded and matched in Tustin, California, where Ronco has operated since 1974. The large moldings that justify a port this size are in our boat tank and RV holding tank categories; see the complete line on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
