ICS Valve Rebuild Kit Letter of Equivalence

Issue

How come part number 057896 (KIT,REBUILD,VLV) has been replaced with part number 075973 (KIT,REBUILD,VLV,6-PORT,6K)?

Why can't I order part number 057896 (KIT,REBUILD,VLV)?

I need a Letter of Equivalence (LOE) for my records to state newer part has same fit, form and function. 

Resolution

If a Customized letter is required, then please request from the IC/SP PSE Team, icsp.productsupport@thermofisher.com.
