This Perko Extra Long Thru-Hull Connection is built for use with pipe thread on thicker hulls. A standard-length fitting wouldn’t reach all the way through a hull this thick.
The flange is machined to fit the hull and grooved to retain bedding compound. The neck is threaded to approximately 3/8 inch from the flange, matching Perko’s standard thru-hull thread pattern.
It’s rated for a maximum hull thickness of 5 inches, cast bronze throughout. Part number 0348DP5PLB identifies the exact fitting for reordering. Shop more thru-hulls and drains.
