The GRACO 903 Seal Cup is a component designed to house and support a Posipak Seal within GRACO fluid handling equipment. Its primary function is to ensure proper sealing and lubrication of moving parts, typically within the valve stack or pump assembly. The material is not explicitly specified in available documentation, but GRACO commonly uses durable plastics or metals for such parts.
