The 10K64 seal assembly is the OEM-specified mechanical seal option for Goulds 3656/3756 S-Group pumps, commonly used for water supply, recirculation, and cooling applications. Please note our seal is 304SS, OEM specification call for 314SS for 10k64 (refer to note below)

*** Build note: Our 10K64 seal is manufactured with electro-polished 304 stainless steel for the spring and other metal components. Some Goulds documentation lists 316 stainless steel for these metal parts. For most standard water/HVAC services, this 304SS build performs reliably; if your application involves aggressive chemicals, or severe corrosion conditions, contact us and we can quote a 316SS option when available.
