Any ideas on what material this is?

Hi everyone,

I'm having trouble identifying the material used in the oil seal of a hydraulic gear pump.

There is a picture of the microstructure of the oil seal with it's hardness.

Any ideas?

Cheers

Seal material depends on what fluid the seal is keeping in or out. The hardness is usually given a Durometer number. The seal shown is generically called a Garlock seal, but there are many manufactures of this type of seal.

The way you can get material is to get the part number off the seal and contact a place that sells seals. They should be able to give material type.

Here is an example of a catalog:
