20 inch water filter housing choices
A 20-inch housing holds a 20-inch cartridge, but the right body depends on your fluid, pressure and temperature. We stock and build plastic housings for water service and stainless steel housings for tougher industrial duty, so you are not forced into one style.
Tell us what you run today, including the brand and part number you are replacing. We will match the connection size, cartridge style and seal so the swap is simple.

Frequently asked questions
How much does a 20 inch water filter housing cost?
Pricing is available on request. Cost depends on material, connection size, sump type and quantity, so we quote each order instead of posting prices online.
Can I get a clear 20 inch housing?
Yes. Clear sump options are available on several plastic housing series, including Big Clear, so you can inspect the cartridge without opening the housing. We will confirm the pressure and temperature limits for your use.
Do you sell replacement 20 inch cartridges too?
Yes. We supply 20-inch cartridges in pleated polypropylene, depth, melt blown, wound, glass fiber, carbon block and cleanable stainless steel, in 2.5 inch and 4.5 inch Big Blue diameters.
What if my line runs hot or at higher pressure?
We offer glass-reinforced nylon high temperature housings and 304L/316L stainless steel single cartridge housings built for high temperature and high pressure service. Send your conditions and we will match a body.
Do you ship across the country?
We serve the United States nationwide, and some products are available internationally. Ask us about stocking arrangements for just-in-time delivery of housings and cartridges.
Do you sell to homeowners?
We sell business to business and quote every order, with no published online pricing. Slim line housings are used in residential and commercial water filtration, so tell us your application and we will let you know what we can supply.
