ASCO Numatics C302927-D2 Solenoid Valve Rebuild Kit

ASCO Numatics C302927-D2 is a rebuild kit designed for ASCO’s 8321-series solenoid valves, specifically compatible with models 8321G003 and 8321G004. The kit provides the essential internal parts needed to restore valve integrity, including body gaskets (large and small), upper/middle/lower inserts, piston O‑rings and lip seals, plus accompanying components such as the main disc, lower disc holder assembly, core spring, retaining cap, machine screws, and a full set of insert and gasket seals. By replacing these internal components, the kit enables serviceable refurbishment of aging valves without replacing the entire unit, helping to recover original sealing and actuation characteristics in pneumatic applications. The rebuild kit is cataloged under part number 302927, and is referenced for use with 8321G003 and 8321G004 valves; when a coil replacement is needed, the compatible coil is listed as order code 238210-032-D, though coils are sold separately from the kit. This makes the C302927‑D2 a practical, downtime‑minimizing solution for maintenance in industrial automation and process-control settings that rely on ASCO Numatics 8321-series valves for dependable, repeatable performance.
