In the Filtration Part Number Search field above enter the part number and click "GO". This is usually found on the bottom "lid" or end cap of the filter. If you have a full assembly - housing plus filter inside - you will need to remove the filter from the housing to obtain an accurate part number. The majority of all Original Equipment Manufacturers filters can also be crossed to a direct replacement for your convenience. (See our Hydraulic Cross Reference Section) This offers you the best lead time, pricing and gives the customer a choice in their filtration needs. We have one of the largest cross reference data bases in the world. Don’t hesitate to contact us for your exact cross if you cannot find it here.
