Details

The Darlly 70405 filter cartridge is built for compatible filtration systems requiring 40 square feet of media with a 2 inch MPT bottom connection. With a 7 inch diameter and 9-3/4 inch length, this cartridge offers a compact form factor paired with a larger threaded base for systems designed around that specific lower connection.

A cartridge like this can be especially important in replacement situations where the overall body size looks similar to other filters but the bottom connection is not interchangeable. Choosing the correct 2 inch MPT version helps support a more accurate fit, cleaner installation, and more dependable filtration performance once the system is back in service.

The Darlly 70405 is a strong fit-specific option for systems that need a 40 square foot cartridge with a broad body and a defined 2 inch threaded bottom connection.
