Hull Fittings and Strainers

Through-hulls are devices that allow pipes or cables to pass through the hull of a boat while maintaining a seal to prevent water ingress. They are used in various systems on board, such as freshwater, seawater, and ventilation systems.

Types of Through-Hulls:

• Screw-In Through-Hulls

  • Description: Use screws to fix the through-hull to the hull. They are often used for larger pipes.
  • Advantages: Easy to install and replace.

• Crimped Through-Hulls

  • Description: Pipes are inserted into the through-hull, which is then crimped to create a seal.
  • Advantages: Provides a good seal and is often used for permanent installations.

• Through-Hull with Gasket

  • Description: Equipped with a rubber or silicone gasket to ensure a tight seal between the through-hull and the hull.
  • Advantages: Provides excellent sealing and is suitable for marine environments.

• Through-Hull with Check Valve

  • Description: Includes a check valve to prevent seawater from entering the boat.
  • Advantages: Protects against water ingress risks and potential damage.

Installation and Maintenance:

• Installation:

  • Location: Choose an appropriate location for the through-hull, avoiding areas where it might be subjected to mechanical stress.
  • Sealing: Use marine-grade sealing products to ensure a secure fit and prevent leaks.

• Maintenance:

  • Regular Inspection: Regularly check the condition of the through-hull and replace the gaskets if needed.
  • Cleaning: Clean the through-hull to avoid the accumulation of dirt that may affect its function
