Forespar 904044ABYC Marelon 1" Full-Flow Seacock with Mushroom Through-Hull

The Forespar Marelon Full-Flow Seacock is an integrated 2-part marine plumbing system that combines a corrosion-proof Marelon valve with a precisely matched 1" mushroom head through-hull fitting. Engineered with super-strong buttress-type threading, this system eliminates the common installation problems of thread mismatches and cross-threading that occur when purchasing components separately.

Constructed from Forespar's exclusive polymer formulation, this seacock will never corrode, making it ideal for harsh marine environments. The full-flow design minimizes flow restriction, while the integrated hose connector simplifies installation and reduces potential leak points.
