Forespar - Marelon ball valves with skin fitting and tails (MF 850)

Forespar

Forespar’s MF 850 series of Ball Valves are precision molded in high strength Marelon®. Their great strength, light weight, and complete freedom from corrosion and electrolysis make them the ideal valve for controlling inlet and outlet water requirements above and below the waterline.

Forespar's engineers opened and closed one of our ¾” (19.05mm) valves 11,000 times, then submerged it in water with an air line pressurized to 40 p.s.i. connected to it.

The result was an absolutely leak free condition with no evidence of wear on internal seals.

Good service
Friday, 26 May 2017  | 

It's a specialist valve for use with aluminium boats. My old one had split and started to leak irrepairably -
possibly because the builder used too much sealer and PTFE when installing. But they are not supposed to break. I ordered it - it arrived in time.

Service was first class, but the product does not quite seem to live up to its claims.
