FORESPAR Marelon® Flanged Seacocks

Cost-effective, corrosion-resistant replacements for older style marine seacocks.

Molded from lightweight, high-strength Marelon, these Flanged Seacocks are highly resistant to corrosion, UV degradation and abrasion. Their NPS parallel threads can be sealed with Teflon® tape or plumber’s putty. Any marine-grade sealant or bedding compound can be used as you would with bronze fittings. In fact, Marelon and bronze fittings can be fitted together as long as you are careful not to cross thread. Marelon is UV stabilized and will not deteriorate in sunlight. Exceed Marine UL and ABYC standards.

Marelon Flanged Seacocks feature female NPS threads on each end. Threads are parallel “NPS,” which stands for “Nominal Pipe Size.”
