Applications
Garlock Klozure seals are spring-loaded rotary shaft oil seals designed to retain lubricants and exclude contaminants from rotating shaft assemblies. The Klozure line has been a standard in demanding industrial and aerospace applications for decades, used in gearboxes, pumps, compressors, turbines, and accessory drives where reliable shaft sealing is required. This unit was originally procured for Teledyne CAE, a manufacturer known for small gas turbine engines used in military drones, target aircraft, and cruise missiles — placing this seal squarely in the aerospace/defense supply chain of the early 1970s. Klozure-style seals of this type are still sought today for maintenance, overhaul, and restoration of legacy aerospace and industrial machinery where the original part specification must be matched exactly.
This Garlock Klozure 521593 oil seal is new old stock (NOS) from aerospace surplus. The seal itself shows no use or wear and appears uninstalled. The original cardboard box is present and intact, though it shows age-related shelf wear consistent with its 1972 manufacture date — light soiling and edge wear on the box exterior. The seal body and lip are clean and intact. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
