Graco 15A054 Air Valve Bushing

Graco 15A054 Air Valve Bushing – Detailed Description

The Graco 15A054 Air Valve Bushing is a precision‑manufactured OEM component engineered to support and guide the internal mechanism of the air valve within Graco diaphragm pumps. It ensures smooth cycling of the pump by providing a stable, low‑friction interface between moving valve elements, and helps maintain accurate air control to drive consistent fluid delivery.

Key Features

• Factory‑specified OEM bushing built for exact fit and performance
• Precision bore and surface finish reduce internal wear and friction
• Promotes smooth movement and alignment of air‑valve components
• Supports high‑cycle, high‑pressure pump operations
• Helps maintain effective air‑path sealing and reliable pump switching

Typical Applications

• Air‑operated diaphragm pumps where accurate air‑valve transition is critical
• Industrial fluid delivery systems requiring consistent pump cycles
• Systems handling coatings, paints, chemicals or abrasive fluids
• When performing maintenance or rebuilds of the air‑valve section of Graco pumps

Installation & Maintenance Advice

Installing the 15A054 Air Valve Bushing requires careful handling to ensure optimal performance and longevity of your pump’s air‑valve system.

• Clean the air‑valve assembly thoroughly before removing the old bushing.
• Inspect the mating surfaces for wear or damage—replace any worn components.
• Install the new bushing carefully, ensuring it seats flush and aligns with the valve body.
• Reassemble the air‑valve using correct torque and alignment practices.
• After installation, cycle the pump at low pressure to verify proper switching and absence of air leakage before full use.

Signs It’s Time to Replace the Bushing

• Erratic or inconsistent pump cycles
• Increased air consumption or poor system efficiency
• Visible wear or scoring on the bushing bore or valve components
• Air‑valve switching delays or misalignment during operation
• Reduced pump output despite normal fluid section condition
