Why Pros Trust Perko Seacocks

• Cast Bronze Construction: Highly resistant to electrolysis and saltwater corrosion, ensuring decades of reliable service.

• Flanged Mounting Base: The wide, pre-drilled flange provides a secure, reinforced mounting point to the hull, distributing stress evenly.

• Stainless Steel Internals: The ball and stem are made of high-grade stainless steel to prevent sticking and ensure a perfect seal every time.

• Safety Locking Handle: The robust handle is easy to operate in tight engine rooms and clearly indicates whether the valve is open or closed.

• Winterization Drain Plug: Includes a side-mounted plug to easily drain water from the valve body, preventing cracked housings in freezing climates.

Care & Maintenance

To ensure your seacock remains easy to operate and watertight:

• Exercise the Valve: Turn the handle from fully open to fully closed at least once a month to prevent marine growth and mineral buildup on the ball.

• Fresh Water Rinse: Periodically rinse the exterior bronze and handle assembly with fresh water.

• Inspect the Seal: Check for leaks around the stem or flange annually.

• Bonding System: Ensure the seacock is properly connected to your boat’s bonding system to prevent galvanic corrosion.

Buying Tip: Don't Forget the Thru-Hull

To ensure a perfect, watertight fit, pair this seacock with a Perko Bronze Thru-Hull Connector. Using matching Perko components ensures thread compatibility and maximum corrosion resistance.
