“Wetted materials” specifications are found in devices that have specific requirements due to the process media. When reviewing wetted materials, it is essential to understand your application’s requirements. Wetted parts should be able to withstand the temperatures, chemicals, and regulations they will come in contact with throughout the span of their intended application.

What are Wetted Materials?

Wetted materials are parts of a component, like a valve or a regulator, that make contact with the liquids, gas, or air that flows through the device. In a simple valve, wetted materials include the body, spring, and seal materials, or any other part that gets wet by the process media. This excludes materials used on the outside of products, such as labels or inks.

Typical Applications of Wetted Materials

Wetted materials are required in a wide variety of applications including:

  • Pipes and related products
  • Mechanical plumbing devices
  • Water filters and treatment units

Among these, one of the more common applications is drinking water and water treatment.

Drinking-Water Filters & Water Treatment

Drinking-water filters are part of most water treatment systems and they remove silt, sand, dirt, and sediments from your water. Some of the most common applications for drinking water filters include:

Reverse Osmosis

Reverse Osmosis

Reverse osmosis is a water purification system that uses a semi-permeable membrane to eliminate unwanted particles and minerals like dirt, salt, fluorine, cryptosporidium, and chlorine from drinking water. It also removes microorganisms, cleaning water down to a molecular level.

Under-Sink Filters

Under-sink filters work in the same way as reverse osmosis. However, they do not eliminate minerals like fluoride and calcium. Under-sink filtration systems filter high volumes of water, don’t take up counter space, and don’t produce wastewater.

Ultraviolet Purification

UV purification is the most effective way to destroy pathogens without altering the water taste. It uses ultraviolet rays to scramble the DNA of disease-causing organisms in the water, rendering them inert and unable to replicate to cause illness. UV purification is an excellent alternative to chemically treated water.


Countertop filtration devices eliminate chlorine, fluoride, lead, pesticides, and other contaminants and minerals from water. It is a cost-efficient option that produces clean, better-tasting water.

Portable Gravity

Portable gravity filters are ideal for removing pathogens that cause E. coli, typhoid, and cholera from water. Thanks to their effectiveness and small size, these filters are widely used by the world’s major emergency relief and aid organizations in field operations.

Bottleless Water Coolers

These filters take water directly from the tap eliminating the need for plastic bottles. Because tap water is more regulated than bottled water, dispensing directly from the tap is more reliable and higher quality than using bottled water.
