Hydac maintains an online Betterfit database that provides cross references for all of its hydraulic filters using either the filter's product description or the manufacturer's typecode. Entering the product description or typecode for a hydraulic filter returns a list of compatible filters manufactured by all of Hydac's major competitors.
While manufacturers produce hydraulic filter elements in a range of common sizes and types, the model numbers they assign to their individual filters often vary considerably from those used by their competitors. Cross reference tools such as Hydac's Betterfit database give customers the model numbers and specifications of equivalent hydraulic filter elements produced by all major manufacturers.
Hydraulic filters are typically standardized parts, so cross reference tools are generally accurate and reliable sources of information. However, even among compatible filters, slight variations sometimes exist. Ensuring that a replacement filter is a good fit requires comparing accurate measurements of the old filter with the dimensions found on the cross reference tool.
In addition to cross references for filters produced by all major hydraulic filter manufacturers, Hydac's Betterfit database also provides filter compatibility information for parts produced by original equipment manufacturers. This information is necessary because many original equipment manufacturers do not offer replacement filters to customers. Additionally, some original equipment manufacturers no longer produce necessary replacement filters, while others have gone out of business entirely.
