Bailey 258142A1 Spare Parts Kit

Bailey 258142A1 Spare Parts Kit is a Bailey Controls maintenance bundle designed to service Bellows Kit A B assemblies used in Bailey control systems and other Bailey hydraulic or pneumatic subsystems that rely on bellows actuation. The kit is identified as part number 258142A1 (also listed as 258142-1) and is tied to NSN 4410-01-239-2215, with Elsag Bailey Inc and Industrial Service And Supply Inc cited as manufacturers in NSN catalogs, reflecting its origin in Bailey's legacy control-part line. Retail listings describe the item as Bailey Controls 258142A1 NSMP spare parts kit, signaling its role as a factory-supplied replacement bundle for bellows components within Bailey equipment. Because the exact component content follows the Bellows Kit A B specification, the kit supports field maintenance and repair tasks for Bailey bellows-based assemblies and should be selected for systems that explicitly call out the A B bellows configuration.
