Groco Bronze Full-Flow Flanged Ball Valve Seacock Seacocks

The Groco Bronze Full-Flow Flanged Ball Valve Seacock is a marine through-hull shutoff valve. It is built for dependable control of raw water intakes, discharges and other below-waterline plumbing. This flanged ball-type seacock is serviceable while installed. It is a durable upgrade or replacement for older seacocks.

Key Features:

• Full-flow design: full pipe-size flow, so water movement through the valve is not restricted
• Bronze construction: corrosion-resistant bronze castings made for marine use
• Stainless steel ball and stem: smooth, durable operation
• PTFE seats and seals: low-friction sealing for reliable shutoff
• Selectable handle rotation: you choose the closed-position orientation (clockwise or counter-clockwise) to suit the installation
• Ratchet-ready handle: the square hole accepts a standard ratchet, which helps with hard-to-reach valves and stiff valves
• Tri-flange base: the bolt pattern matches most popular brands, which makes retrofits easier
• Bonding attachment: built into the base
• Serviceable when installed: drain plugs on both sides help with winterization
• UL listed for marine use

Larger sizes in the line include a grease zerk fitting for lubrication. It can also be used for draining. Not for use in potable water systems.

Groco is a well-known name in marine plumbing. This seacock line suits sailboats, powerboats and other vessels that need a strong, serviceable through-hull valve.
