Oil Seals for Heavy Equipment and Machinery

Find replacement oil seals for heavy equipment, hydraulic systems, engines, and industrial machinery at Fab Heavy Parts. Oil seals help retain lubricating oil or other fluids around rotating shafts and help limit contamination from dust and debris. Selecting the correct seal is important for reducing leakage and maintaining the performance of the assembly it serves.

This collection includes oil seals and seal kits for selected excavators, loaders, hydraulic pumps, swing drives, travel motors, and air compressors. It also includes related products such as oil seal installation tools.

Hydraulic Pump, Swing Drive, and Travel Motor Oil Seals

Explore oil seals for selected hydraulic pumps and rotating drive assemblies. Examples in the collection include Caterpillar swing drive oil seal 128-9170, Case hydraulic pump oil seal LE018730, and a travel motor oil seal kit for the Komatsu PC120-6E. Each listing specifies its own application, so these products should not be treated as interchangeable. 

When replacing a seal, inspect the sealing surface and related components for wear or damage. A new seal may not resolve recurring leakage if the shaft, housing, bearing, or other mating surface is damaged.

Engine and Air Compressor Oil Seals

The collection also includes oil seals for engine-related applications and industrial air compressors. For example, oil seal 1616754800 is listed for Atlas Copco GA7 and GA11 air compressors. Other listings cover crankshaft oil seal applications and compressor components. Check the individual product details to confirm the intended equipment and part number. 

How to Identify the Correct Replacement Oil Seal

Start with the part number on the original seal whenever possible. Also compare the machine or engine model, application, and listed dimensions. Seal type, inner and outer diameters, width, material, and operating conditions can all affect suitability; similar-looking seals are not necessarily compatible.

If you cannot find a matching listing, request a quote with the original part number and equipment details to help identify the appropriate replacement.
