Forespar Marelon Full Flow Seacock

$88.45 to $229.54

$88.45 to $229.54
These "93 Series" seacock assemblies are made of exceptionally strong, fiberglass-reinforced Marelon®. Marelon is both electrically and chemically inactive - making for easy installation, very low maintenance, and long service life for the end user, without the worry of possible corrosion over time. It is very light weight, has exceptional UV resistance, and will not freeze or become brittle with age.
Marelon exceeds ISO standards, is approved by the ABYC, and passes the same stringent Marine UL tests as bronze.
These valves are sold as a complete system consisting of the thru-hull, valve body and a 90° tailpipe barb. The thru-hulls use a buttress style thread for exceptional strength and are not compatible with any other valves.
  • Lightweight, yet extremely strong injection-molded parts
  • Complete freedom from any corrosion
  • Complete freedom from electrolysis or reaction to any metals
  • Outstanding operating temperature range (-22° to +176° F)
  • Long term reliability
  • BSPP threads available by request
