What is the difference between a standard brass safety unit and one in stainless steel?

The material is different at the seat of the safety unit. Some are brass, some are stainless steel. Which one is appropriate depends on the aggressiveness of the water. Stainless steel reduces the problems caused by water that is too aggressive or too hard.

The stainless-steel valve seat in the COMAP stainless-steel 889 safety unit is guaranteed for 10 years.
