Groco Bronze Full-Flow Flanged Ball-Type Seacock Seacocks

Groco Bronze Full-Flow Flanged Ball-Type Seacocks are marine through-hull shutoff valves. They control water flow for intakes, discharges, and other below-waterline plumbing. They are made from C84400 bronze and have full-flow ports, so water passes through at the full pipe size with no restriction. This is a dependable choice for engine cooling, livewell, washdown, and bilge plumbing, and as a replacement ball-type seacock.

Key Features:

• Full-flow design: full pipe-size flow keeps water moving without the restriction found in many other ball valves.
• Bronze construction: C84400 bronze body for durability in marine use.
• Selectable handle rotation: the patented design lets you choose the closed-position direction in the field. This helps in tight or otherwise hard-to-use locations.
• Ratchet-compatible handle: a square opening accepts a standard ratchet. This makes hard-to-reach or stiff valves easier to operate.
• Smooth, sealed operation: stainless steel ball and stem with PTFE seats and seals.
• Easy retrofit: the tri-flange base and mounting hole pattern are designed to replace most popular brands.
• Serviceable while installed: you can maintain the valve in the field without removing it.
• Winterization-friendly: drain plugs on both sides allow efficient draining.
• Bonding attachment: the base includes a bonding attachment.
• UL Listed: listed to UL 647B.

Larger sizes include a grease zerk fitting that can be used for lubrication or draining. Not to be used in potable water systems. Groco is a long-established name in marine plumbing, and these seacocks give boat owners a strong, serviceable shutoff valve for critical through-hull applications.
