Type 5620/5620P

Universal Cartridge Seal Family — Dual Cartridge O-ring Seal

The first truly universal cartridge seal, the Type 5620/5620P will change your approach to sealing. Since the 5600 Series components are interchangeable, you can apply one seal family throughout your plant. This gives you the flexibility to cover more applications with less inventory, which means your maintenance is simplified, downtime is reduced, plant operating efficiency is increased and costs are lowered. Designs available conform to API 682, Category 1.
