Graco 117600 Washer Felt Overview

The Graco 117600 Washer Felt is a precision felt component engineered for high-pressure fluid systems. It ensures reliable sealing, protects pump components, and maintains consistent performance in industrial and professional spraying applications.

• Inner Diameter: 15/16"
• Outer Diameter: 1-1/2"
• Material: Dense wool felt for high-pressure resistance
• Performance: Maintains sealing integrity up to 6000 psi
• Maintenance: Inspect regularly for fiber wear or clogging

Material Composition

Constructed from wool felt with uniform fiber orientation and controlled density, offering compressive resilience and stability under cyclic loading from -20°C to 80°C. Porous structure traps abrasive particles while allowing controlled fluid passage.

Mechanical Durability

Withstands high-frequency pump cycles, maintaining shape and integrity. Abrasion resistance is verified with minimal wear under ASTM D3389 Taber testing. Fatigue resistance ensures predictable maintenance intervals.

Installation & Usage

Seat precisely in pump gland cavities, pre-lubricate with compatible fluid, and secure with correct torque. Periodic inspection is recommended to detect fiber migration or surface erosion to maintain consistent pump output.
