Key Features
- Durable lower housing designed to house the diaphragm securely.
- Provides a stable seat for the diaphragm plate and membrane during pressurization.
- OEM-grade construction for perfect integration with Graco diaphragm systems.
- Facilitates reliable, leak‑resistant operation through effective structural support.
- Accessible for maintenance and rebuilds without excessive disassembly.
Technical Specifications
| Specification | Detail |
|---|---|
| Part Number | 15A218 |
| Component Type | Lower diaphragm housing |
| Material | Machined metal / die-cast (Graco OEM specification) |

| Compatibility | Used in Graco pneumatic regulator assemblies (e.g., models 233813, 234259) |
Applications & Usage
- Commonly used in Graco pneumatic regulators where the diaphragm requires a rigid, secure housing.
- Ideal for systems with frequent cycle variations, providing long-term structural support.
- Helps ensure reliable diaphragm performance and longevity, minimizing risk of fatigue or misalignment.
Maintenance Guidance
- Inspect the lower housing during diaphragm servicing or rebuilds to check for cracks, wear, or deformities.
- Clean the housing cavity thoroughly before reassembling to ensure no debris affects the diaphragm or plate.
- When reassembling, apply the correct torque to mounting bolts as per Graco specifications to maintain structural integrity.
- Replace the housing if any damage is found—compromised housing can lead to poor diaphragm operation or leaks.
FAQs: Frequently Asked Questions
It forms the structural foundation for the diaphragm assembly, securing the diaphragm, platelet, and other internal components during operation.
It is used in Graco pneumatic regulator assemblies such as models 233813 and 234259.
Replace the housing if you observe physical damage, deformation, or cracks when performing diaphragm maintenance. A compromised housing can lead to poor sealing and reduced diaphragm life.
