- Heavy‑duty material resists deformation under load
- Correct bolt‑pattern and installation geometry
- Ideal for replacement when mounting integrity is compromised
Compatible Machines for the 15H478 Plate Retainer
- Graco spray modules and pump systems that use retaining plates to secure internal components
- Maintenance scenarios where retaining plates show wear, distortion or loosening of bolts
Product Overview
The 15H478 Plate Retainer is a critical structural component in Graco pump and fluid systems, designed to hold internal plates, assemblies or manifold blocks securely in place. When the retainer plate becomes worn, bent or the fasteners loosen, system alignment suffers—leading to vibration, leakage or reduced lifespan. Replacing with the correct retainer restores alignment, clamp load and machine integrity.
Manufactured to precise standards, this plate ensures the correct spacing, alignment and bolting pattern for safe secure assembly under pressure and dynamic fluid conditions.
Key Features
Inspect during each major overhaul or if you notice mounting fasteners loosening, component movement or alignment drift — early replacement prevents larger system issues.
