GROCO 1-Inch Ball Valve Seacock Strainer Combo

The GROCO 1-Inch Ball Valve Seacock Strainer Combo gives positive shutoff for a compatible below-waterline marine plumbing connection. Its bronze body and full-flow ball-valve design allow the intake or discharge line to be isolated for maintenance, winterization, or emergency control while supporting unrestricted flow when fully open.

This combination model integrates the seacock and raw-water strainer into one space-saving assembly, reducing the number of separate components and bilge locations that require access for service. These service-oriented details are especially useful where valves are installed in crowded bilge spaces with limited hand clearance.

Confirm connection size, thread type, thru-hull compatibility, flange mounting, handle clearance, bonding requirements, flow direction where applicable, 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.

• The ball valve gives positive isolation for service or emergencies.
• The valve geometry minimizes unnecessary restriction in the plumbing path.
• Handle features on supported models improve access in crowded bilges.
• Drain, lubrication, or integrated-strainer provisions simplify maintenance where equipped.
