The 4615 is a metal bellows seal that replaces the EZ-1®General-purpose Single Cartridge Seal. It is a member of the 4600 family of cartridge seals.  Like other Type 4600 series cartridge seals, the 4615 design provides reduced installation times, lower maintenance costs and optimal equipment performance; and is ideal for the chemical, pulp and paper, wastewater, food processing and power generation industries. The abrasion and corrosion-resistant Alloy 20CB3 SS bellows enhance reliability by eliminating dynamic O-ring hang-up caused by process contamination, thermal gradients, and material deficiencies. The 4615 replaces the EZ-1®General-purpose Single Cartridge Seal, offering improved value and availability.
