The Gast AA405 Gasket Muffler/Filter at Kinequip is a molded sealing component designed for use in Gast air compressors and vacuum pumps. It serves a dual function—sealing the muffler/filter housing while helping reduce noise and prevent particulate contamination in the airflow system.
Made from durable elastomeric material, the AA405 maintains a tight seal under varying pressure conditions and resists wear from vibration and chemical exposure. It is commonly used in maintenance and repair of Gast units where the muffler/filter interface requires reliable sealing.
This gasket is compatible with several Gast models and is often included in service kits or sold as a standalone replacement part. Installation is simple and does not require adhesives or special tools, making it ideal for quick field repairs.
