Perko 1-Inch Bronze Seacock Ball Valve, Made in USA

The Perko 1-Inch Bronze Seacock Ball Valve, Made in USA gives positive shutoff for a compatible below-waterline marine plumbing connection. Its bronze valve body allows the intake or discharge line to be isolated for maintenance, winterization, or emergency control while supporting normal flow when open.

Marine seacock construction gives a flanged mounting base for a secure hull-side installation, with service features varying by model. Perko versions use a polymer ball and seat or bronze ball-valve design, while compatible GROCO installations can use dedicated backing hardware for a strong mounting foundation.

Confirm pipe or hose size, thru-hull compatibility, flange mounting, handle clearance, bonding requirements, and service access before installation. Use appropriate marine bedding and fasteners, exercise the valve periodically, and inspect the assembly for smooth operation, corrosion, and leaks. Take a look through our bilge and water pumps.
