Filter Housing

Vili's products have the following features:

Filter Cartridge Housings: This is the most direct name for the component you've described. It holds a filter cartridge and is made of materials like polypropylene.

Industrial Water Filter Housings: If the application is water filtration, this term is more specific.

Filter Housings: Given the "polypropylene" and "stainless steel" materials, this could be for use in chemical dosing systems where corrosion resistance is important.

High-Flow Filter Vessels: This term is used for larger versions of these housings, particularly those with a 4.5" diameter, which are often classified as "big blue" or "jumbo" housings.
