Forespar 904046ABYC Marelon 1.5" Full-Flow Seacock with Mushroom Through-Hull

The Forespar Marelon Full-Flow Seacock with 1-1/2" Mushroom Through-Hull is an integrated 2-part marine plumbing system that combines a Marelon valve with a perfectly matched mushroom head through-hull fitting. This complete system features super-strong buttress-type threading designed to eliminate the valve and through-hull mismatches and cross-threading issues that commonly occur when purchasing individual components separately.

Key Features:

• Complete system includes full-flow seacock with integrated hose connector and mushroom through-hull
• Exceeds ABYC H-27 standards and UL approved for reliable performance
• Suitable for use above or below the waterline
• Constructed from exclusive Marelon polymer formulation that never corrodes
• Includes emergency handle cap through-hull plug for added safety
• Buttress-type threading ensures proper fit and prevents cross-threading

The Marelon construction provides superior corrosion resistance compared to traditional bronze fittings, making this seacock system ideal for long-term marine applications. The full-flow design minimizes flow restriction for optimal water intake performance.
