“K” Type compressor head for using an SD5H14 compressor in our Klima Compressor Upgrade Kits. If you have a Sanden 508 or SD5H14 compressor from a different application and you want to convert it to run in the upgrade kit, this kit will come in handy. This is the same head that comes standard on the SD5H14 Model 6630. We have upgraded our compressor recommendation to the SD7H15, but if you have one of these compressors you can still use it with our kit. Your purchase includes the head, replacement gasket, and specialty “shorty” 43mm fine pitch flange bolts required for use with this head (yes, you need the bolts too! Most Sanden heads use longer bolts, which should not be cut or re-purposed). Fits Sanden 508 and SD5H14. Install according to instructions in Sanden SD Service Guide.
