Specifications

Important: I found consistent evidence that 250040-892 is a Sullair kit/diaphragm repair set, but the available sources do not establish a reliable specific compressor model. Sullair recommends providing the compressor serial number when ordering parts, so compatibility should be verified before purchase.
