Inside and outside: Do industrial strainers have to be made of stainless steel?
A whole range of materials is suitable for the housing and cover of your strainer, all of which have different advantages. The decision always depends on your individual case. At Fergo, the choice is yours. We offer you over 100 items made from the following materials:
- Brass
- Brass (nickel-plated)
- Stainless steel
- Steel
- Grey cast iron
- Ductile cast iron
If, for example, maximum temperature resistance is important to you, a stainless steel strainer is probably really recommended. This also provides excellent corrosion protection. If, on the other hand, moderate strength is sufficient, but the strainer is to cover a heating system or applications with drinking water, we recommend brass. More aggressive media such as chemicals may even require PFA-lined fittings.
You can find suitable solutions in the Fergo Shop. Whether you work with high pressures or simply prefer the extremely robust version, we can equip you.
If you still have any questions in the first step, just let us know. Our support team will be happy to advise you on the products and their application.

Flange strainer in Y-shape or sockets?
Long before the fitting is actually installed, you should know how best to integrate it into your system. In industry, strainers with a flange connection are popular because they remain stable even when the pipes are subjected to stress. This type is also the standard for larger nominal widths. Socket strainers on the other hand only rarely exceed DN50. They are very compact and inexpensive, making them ideal for in-house building services or heating systems, for example.
The size of the average system and therefore the filter used alone often make a difference. A flanged strainer manufactured according to DIN specifications makes it possible to change strainers in no time at all. Ultimately, both types of connection reliably protect a suitable system against foreign bodies in the transported medium - if you pay attention to quality when purchasing. So put your trust in the high-quality fittings from Fergo!
