Graco 15G492 Cover Board

The Graco 15G492 Cover Board is a precision-engineered accessory designed to serve as a robust interface component in high-performance spray systems. It offers structural rigidity and exact geometry to maintain optimal seal integrity and fluid routing in demanding industrial environments.

Key Features & Specifications

Dimensions Approx. 2.05 in (H) × 7.3 in (L) × 2.75 in (W) — precision-cut to fit specified equipment.
Material & Finish High-grade aluminum alloy, with machining to tight tolerances and protective surface treatment for wear and chemical resistance.
Function Acts as a cover board across pump or manifold assemblies to maintain flatness, minimise dead volume, align sealing surfaces and enhance system efficiency.
Performance Focus Supports high-flow and high-pressure applications by reducing turbulence and maintaining uniform shear across fluid paths.

Why Choose This Cover Board?

This cover board is ideal for systems requiring dependable structural support, precision alignment, and maintenance of seal integrity over time. Using the specified 15G492 ensures interfaces remain reliable, leaks are prevented, and equipment downtime is minimised in professional spray environments.

Installation & Maintenance Tips

  • Ensure the system is depressurised and power is disconnected before installation.
  • Clean mounting surfaces and remove old sealants or residues to promote correct seating and sealing.
  • Install the board using the manufacturer’s recommended torque and alignment aids to avoid distortion.
  • During routine checks, inspect the board’s surface flatness, mounting hole wear and seal interface for signs of leakage or misalignment.
  • Replace the board if you detect fatigue, warping, or if system performance (e.g., flow or pressure stability) deteriorates.

Frequently Asked Questions

This board is designed for specific high-pressure systems. Always verify equipment model, mounting pattern and interface geometry before installation.

Replace the board when you notice distorted mounting surfaces, fluid leaks at interfaces, or decreased system performance such as unstable pressure or flow.

Using a non-OEM board may result in improper fit, increased dead volume, poor sealing, and accelerated component wear—potentially causing downtime or coating defects.
