FLANGE MOUNTING SEACOCKS
Forespar’s Flange Mounted Seacocks made with Marelon
®
offer superior strength and corrosion resistance compared to
conventional bronze type valves. Strong, lightweight, corrosion
and electrolysis free, they make the ideal thru-hull valve.
Available in most common sizes and thread configurations,
Marelon Seacocks can be used as replacement valves for most
existing marine thru-hull fittings.

All our valves are non-corrosive, but like any moving part in a marine environment, they require
regular inspection and lubrication. Do not fail to actuate the handle and lubricate the seals on a
regular schedule.
For proper and easy valve lubrication, we recommend our new MareLube Reach valve lubrication
kit. It allows you to inject the correct lubrication directly onto the valve’s moving parts using a pre-
loaded syringe and extension tube. Water pump grease or mineral oil can also be used if necessary.

MF 850 BALL VALVES
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.
Our engineers opened and closed one of our 3/4”(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 internal seal wear. Valves sold throughout the U.S.A. have parallel
marine type threads. If specified, B.S.P. are available outside of America.
