Marelon Forespar Pro 93 Series Ball Valve

Forespar 93 Series Threaded Valves are the best Glass Reinforced Composite Polymer Marine Plumbing Components. They can be used above or below the waterline and will never corrode. They are extremely OEM configurable, and some are compatible with brass/bronze fittings with BSP-style threads. The Marelon® “93 Series” plumbing system comes standard with buttress threaded thru-hulls that mate to buttress threaded valves.

Marelon® Pro Series Valve Inline Female Threaded Base with Female Threaded is designed to meet the needs of builders and owners who require the benefits of the Marelon® integrated plumbing system, with BSP style threads. This valve works excellently with ANP Thru-Hulls.

Marelon® is the modern material for marine plumbing systems. Its non-corrosive proprietary formulation of polymer composite compounds uses resins and additives to produce an extremely strong marine-grade product that will not deteriorate like traditional bronze marine plumbing parts.
