MF 850 Marelon Full Flow Ball Valves

These Ball Valves have NPT straight threads at each end, and are designed to be fitted with straight thread thru-hull or pipe fittings.
Pipe joint compound or teflon tape is required to create a perfect seal.

These valves 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.
