What Gasket is Used for Seawater?

Question: What gasket is used for seawater?


Seawater is a corrosive medium, and gaskets used in seawater applications must be resistant to corrosion and have good sealing properties. Two commonly used materials for seawater gaskets are:

1. Rubber gaskets: Gaskets made of materials such as EPDM, Nitrile (NBR), or Neoprene are often used in seawater applications. These gaskets provide good resistance to seawater, ozone, and UV exposure, and can be used in a range of temperatures.

2. Non-asbestos gaskets: These gaskets are made of a combination of aramid fibers, mineral fibers, and fillers, and provide good sealing properties and resistance to seawater corrosion. They can be used in a wide range of temperatures and pressures.

In addition to these materials, some gasket manufacturers may also offer gaskets made of materials specifically designed for seawater applications, such as marine-grade silicone or Viton.

When selecting a gasket for a seawater application

it’s important to consider factors such as the specific chemical and temperature properties of the seawater, the type of equipment being sealed, and the operating conditions of the application to ensure that the gasket provides the required level of performance and longevity.
