Graco 15H179 Deflector Quiet Manifold

Compatible Machines for the 15H179 Deflector, Quiet Manifold

• Graco high‑pressure fluid distribution manifolds
• Graco coating systems using “quiet manifold” technology
• Industrial spray systems requiring deflector plate replacements

Product Overview

The 15H179 Deflector, Quiet Manifold is a precision‑engineered component designed for fluid‑handling systems where noise reduction, stable flow and reliable sealing are essential. This deflector plate is integrated into manifold assemblies to redirect fluid flow, minimise turbulence and enhance operational lifespan of spray equipment.

Crafted for professional use, this deflector offers enhanced durability, smoother internal flow transitions and quieter operation through a tough construction and optimised geometry. It supports efficient system performance and helps maintain consistency under heavy use conditions.

Key Features

Installation & Usage Tips

• Shut off the system and relieve all fluid pressure before servicing the manifold assembly.
• Disassemble the manifold and remove the old deflector plate; clean the mating surfaces thoroughly to remove residue or damage.
• Install the 15H179 deflector, aligning the bolt‑holes correctly and ensuring full surface contact with the manifold housing.
• Tighten fasteners to the manufacturer’s specified torque values to prevent distortion and ensure a proper seal.
• After installation, operate the system at low pressure and listen for noise or irregular flow; then resume full operation once normal behaviour is confirmed.
• During routine maintenance, inspect the deflector surface for erosion, pitting or wear—addressing these issues early helps maintain efficient performance and longer service life.
