Compatible Machines for the 15H190 Seal Diffusion Exhaust
- Graco high‑pressure airless sprayer systems
- Fluid‑handling manifolds and multi‑head coating rigs
- Industrial spray applications using diffusion and exhaust control modules
Product Overview
The 15H190 Seal Diffusion Exhaust is a high‑performance sealing module engineered for demanding fluid delivery systems. It features a compact design and lightweight construction to seamlessly integrate into existing sprayer manifolds, delivering reliable containment and enhanced flow control.
Designed for endurance and precision, this seal assembly supports consistent fluid diffusion, minimized back‑pressure, and longer service intervals—ideal for industrial coating, high‑load environments, and professional finish systems.
Key Features
| Feature | Description |
| Compact & Lightweight Design | Minimal footprint allows integration into tight manifold assemblies without adding bulk. |
| High‑Precision Sealing Module | Engineered with advanced polymer and elastomer materials for tight sealing and minimal leakage under pressure. |
| Optimised Flow & Exhaust Path | Internal geometry is tuned for smooth material flow, reduced turbulence, and consistent diffusion of fluids and gases. |
| Durable Construction | Built with rugged materials that withstand cyclic loads, abrasive fluids, and job‑site conditions. |
Installation & Usage Tips
- Shut down the machine and relieve any residual fluid or air pressure before servicing the manifold.
- Remove the existing seal module and clean the mating surfaces to ensure a smooth interface.
- Install the 15H190 module, aligning bolt holes and sealing surfaces correctly to avoid leaks or misalignment.
- Tighten fasteners to specification and inspect for full surface contact and proper clearance.
- After installation, test the system at low pressure to confirm proper function before returning to full operation.
- During routine maintenance, inspect the seal for signs of wear, leakage or deformation and replace as needed to maintain peak performance.
???? Frequently Asked Questions
The module provides controlled diffusion and exhaust pathways within high‑pressure manifold systems, helping to stabilise flow, reduce back‑pressure and maintain sealing integrity.
Installation is straightforward with correct preparation: depressurise system, clean surfaces, align module and torque fasteners properly. No major modifications are required.
Regularly inspect for wear, leakage, and surface damage. Keep the module clean from debris and sediment build‑up, and replace promptly if any performance degradation is observed.
