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. Also cross-references as MDKN21004.
