CBC-3.1-20 Water Filter

0.5 Micron Nominal Filtration
20" x 3.1"

Pentek CBC-3.1-20 and Ametek CBC-3.1-20 replacement carbon block water filter for Seal-Safe

CBC-3.1-20 Seal-Safe Carbon Block Cartridge

DISCONTINUED

There is no direct replacement filter. In most housings that use the Seal-Safe Cartridges, you may use double open end filters such as the CBC-20 water filter.

The HEP-1-3.1-20 Seal-Safe Cartridge is still manufactured, but it is a pleated sediment filter and not a carbon block filter cartridge.
  • Pentek / Ametek CBC-3.1-20 Water Filter:
  • Nominal 0.5 Micron Seal-Safe Water Filter Cartridges
  • Seal–Safe™ (patent pending) double o–ring sealing cartridges are 3.1" in diameter and ideal for critical applications where a positive seal is required.
  • These carbon block cartridges contain approximately 20% more carbon than standard CBC cartridges and 8% more surface area for enhanced capacity and cartridge life. These cartridges also feature Endurawrap™ to protect the block from fine sediment and to enhance its useful life.
