The GRACO 803919 is an anti-extrusion ring designed to prevent the extrusion of seals or O-rings in high-pressure equipment. Its material is not specified in available sources, but it is typically made from durable polymers or engineered plastics for longevity and resistance to wear. The ring is intended for use within GRACO pressure washers and spray equipment to maintain seal integrity and prevent leaks under pressure.

Key Features:

• Anti-extrusion ring
• Height: 0.1 in (0.254 cm), Width: 0.15 in (0.381 cm)
• GRACO pressure washers and spray equipment (e.g., Direct-Drive Pressure Washers, Hydra-Clean Pressure Washers)
• Prevents seal extrusion under pressure
• Enhances equipment reliability
• Supports long service life of seals

Applications:
Used in GRACO pressure washers and spray equipment to protect seals and O-rings from extrusion and failure during high-pressure operation.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and equipment longevity.
• Inspect the ring for damage before installation.
• Ensure the ring is seated correctly to prevent seal extrusion.
• Follow GRACO equipment manual instructions for installation and maintenance.
• Replace anti-extrusion rings during routine maintenance or when seals are replaced.
• Use only GRACO-approved parts for optimal performance.
