1187214 HNBR O-Ring for Caterpillar Equipment

HNBR O-ring, SKU 1187214, for use in equipment manufactured by Caterpillar. The seal is a standard O-ring with a black hydrogenated nitrile rubber construction, 78 Shore A hardness, and an operating temperature range of -40°F to 275°F. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The available product data identifies Caterpillar as the equipment manufacturer but does not specify individual machine models or series. Fitment should therefore be verified by matching the dimensions, material, hardness, and reference number with the seal location and parts documentation for the applicable Caterpillar equipment.
