This new old stock 90mm M46 Patton Tank Gasket Set is an authentic U.S. military surplus component, issued under National Stock Number 5330-00-776-7369 and Part Number 7767369. While the exact system within the tank this gasket set is intended for remains undetermined, it was specifically manufactured for use on the 90mm M46 Patton Medium Tank—one of the foundational armored platforms of the early Cold War.

The M46 Patton, introduced in 1949, was developed as an interim solution between the WWII-era M26 Pershing and the more advanced M47 and M48 series. Featuring a 90mm M3A1 gun, improved fire control, and a Continental AV-1790 engine with Allison cross-drive transmission, the M46 saw combat use during the Korean War. As a transitional tank, it set the standard for post-war American armor design and deployment.

Gasket sets like this one would have been critical in maintaining pressure seals, fluid containment, and component interfaces throughout various mechanical or hydraulic systems on the tank. Whether used in the breech mechanism, recoil assembly, or engine compartments, original gaskets are vital for ensuring restoration accuracy and mechanical function.
