1505884 Ring for Caterpillar

1505884 is a transmission seal back-up ring used in Caterpillar equipment, including excavators, wheeled excavators, wheel-type loaders, material handlers, and forest products machines. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The ring supports the sealing system in high-pressure applications and helps prevent seal extrusion during pressure increases.
