Perko 0350006DPP Plain Bronze Thru-Hull Connection for 1 Inch Hose

The Perko 0350006DPP is a plain cast bronze thru-hull connection designed for use with 1 inch hose. It provides a through-hull passage for plumbing and drain lines, allowing hose to be routed from inside the hull to the exterior of the boat. The flange is machined to fit flush against the hull surface and is grooved to retain bedding compound, helping create a secure, leak-resistant seal when properly bedded and through-bolted during installation. The neck is threaded to approximately 3/16 inch from the flange to accept a matching seacock or fitting.

This connection is built from solid cast bronze for corrosion resistance in a marine environment and is sized for 1 inch hose, with a mounting hole diameter of 1-5/16 inches and a maximum hull thickness rating of 1-3/4 inches. The flange outer diameter measures 2-1/4 inches. This thru-hull connection is intended for use with hose only and is not recommended for use below the waterline, per A.B.Y.C. Safety Standards for Small Craft, Section H-27.
