The Forespar Marelon Full-Flow Seacock is an integrated 2-part marine plumbing system that combines a high-performance valve with a matched 3/4" mushroom head through-hull fitting. This complete package features super-strong buttress-type threading designed to eliminate the thread mismatches and cross-threading problems common when purchasing components separately.

• Complete system includes full-flow seacock with integrated hose connector and mushroom through-hull
• Exceeds ABYC H-27 standards and UL approved for marine safety
• Suitable for above or below waterline installations
• Constructed from exclusive Marelon polymer that never corrodes or deteriorates
