The Midland Haldex KN21004 is a manual drain valve for heavy-duty air brake wet and dry reservoirs. It features a high-profile design and ships with a 48-inch unclasped cable and ferrule already included, so no separate cable kit is needed at installation. The valve installs via a 1/4-inch NPT male thread with pre-applied sealant, making it compatible with a wide range of air tank configurations. It allows complete draining of air reservoirs to purge accumulated moisture and contaminants. Call us to confirm proper fit for your specific tank and plumbing configuration.
