Flowserve 101389 Mechanical Seal Cartridge 1.5" Double Dura Seal is a dual-seal cartridge designed for rotating equipment that requires a compact, replaceable seal assembly. The 1.5-inch size specifies the cartridge form factor, while the Double Dura Seal configuration provides two sealing interfaces within a single unit. This Flowserve part carries the 101389 designation as part of Flowserve's standard mechanical seal cartridge lineup, offering a straightforward alternative to traditional seal installations.
