Gast K478 Air Compressor Repair Kit 9 Piece

Product Description

The GAST K478 is a 9-piece repair kit designed to restore proper operation in GAST 0323 and 0523 series oil-less compressors with internal filtration. The kit contains the consumable and wear components most commonly replaced during scheduled maintenance or after-failure service, including O-rings, a gasket, filters, vanes, and instructions. Weighing 3 pounds and packaged in a 10 x 10 x 3 inch box, it ships as a complete service set so technicians can complete the repair in a single work order without sourcing individual components separately.

This kit is intended for use on GAST 0323 and 0523 oil-less compressor models fitted with internal filtration, commonly referred to as the Q configuration. These compact oil-less compressors appear in medical, laboratory, industrial, and pneumatic control applications where clean, dry air output is required. The repair is typically performed during scheduled preventive maintenance intervals or when output pressure drops due to worn vanes or failed seals.
