Seacock 1" Flush, 90 Degree Hose Barb

Part #: Z3860
This 1" seacock valve with a 90 degree hose barb became standard equipment on many Catalinas towards the end of 1993.

Molded Marelon offers superior strength and corrosion resistance. Marelon is lightweight, corrosion and electrolysis free, ideal for thru-hull valves. Marelon is a modern material formulation of polymer composite compounds that uses resins and additives to produce an extremely strong marine-grade product that will not deteriorate like traditional bronze marine plumbing parts. Ideal for above and below the waterline applications.

For emergency service:

Remove the attached white plug covering the screw at the axis of the rotation of the handle. Fasten it to a lanyard. Plug the intake from the outside of the boat. After servicing the valve, use the lanyard to dislodge the plug and bring it aboard to be be stowed on the valve for its next use.
