GROCO Full-Flow Flanged Bronze Seacocks

Replace your older style marine seacock with a bronze seacock that is serviceable while installed.

Groco’s Full-Flow Flanged Bronze Seacocks feature all-bronze castings with stainless steel full-flow balls and glass-reinforced PTFE seats and seals. 1 1/4″ sizes and larger include one grease zerk fitting for lubrication (use only with the valve in the open position) and one drain plug. The zerk can also be used for draining. The tri-flange base has a bolt pattern that matches most popular brands to make retrofits easier.

Patented selectable handle rotation allows you to select the closed position orientation (clockwise or counter-clockwise) that best suits the installation. The handle has a square hole to accept a standard ratchet, to help reach valves in hard-to-reach locations and to make difficult-to-operate valves easier to actuate.

The top fittings are NPT (tapered thread) and bottom are NPS (straight thread). Marine UL-listed.
