Jabsco 18753-0357 - Seal Carbon Nitrile
The mechanical seal you are looking for is specifically designed for a Jabsco pump. It features a Carbon Rotary Face/Primary Ring, 18-8 Stainless Steel Retainer, 18-8 Stainless Steel Spring, and Nitrile Bellows/Elastomers. This seal is compact, unitized, unbalanced, and has a single spring with bi-directional capabilities. The one-piece construction allows for easy installation and replacement. With a full-convolution Nitrile elastomer bellows, this seal offers maximum flexibility to compensate for shaft movement and wear. Torsional stress on the bellows is managed by a dent and groove positive drive arrangement. The precision surface finish enhances service life and reliability. The Nitrile elastomer drive ring securely grips the shaft for effective sealing and drive, eliminating the need for set screws or drive pins. The coil spring and ferrules ensure consistent face loading even in extreme working conditions.
