Brass vs. Zinc-Plated Steel Pressure Switch Housing for Water Service Applications
June 21, 2021
When monitoring water supply and water pressure, it is essential to ensure that the components used are designed to be compatible with water. The more common pressure switches (PS61 Series and PS71 Series) feature a 12L14 steel housing that is Zinc-plated. For water applications, the Zinc-plated steel will eventually rust. Allowing rust into the water system is not ideal.
To overcome this, Gems has two options for water service:
Brass Housing: PS41
Brass is highly resistant to corrosion and resists attacks from minerals and acids that are often found in water.
Stainless Steel Housings: PS61 and PS71
Stainless Steel is a non-toxic material that is also corrosion resistant and will not leach into the water system.
The PS41 Series, with its standard brass housing, and the PS61/PS71 Series, with their optional stainless-steel housings, make an ideal pressure switch for water applications.
