Graco 15B500 FDA Viton 1040 Diaphragm – Product Details & Compatibility
Compatible Machines
The Graco 15B500 FDA Viton 1040 Diaphragm is engineered for use in the diaphragm chamber of the Graco Husky 1040 series (and equivalent 1040‑series sanitary models) air‑operated double diaphragm (AODD) pumps where a Viton (fluoroelastomer) diaphragm and FDA‑rated performance are required.
- Graco Husky 1040 AODD pumps and sanitary variants requiring FDA‑compliant Viton diaphragms
- Pump systems in chemical, food‑grade, coating, or sanitary fluid‑handling applications designated for the 1040 series
- Replacement or service kits aimed at restoring diaphragm performance, sealing integrity and longevity in high‑cycle pumps
Product Overview
The Graco 15B500 FDA Viton 1040 Diaphragm is a precision‑manufactured component made of FDA‑rated Viton elastomer, designed to meet the demands of one of Graco’s most robust pump series: the 1040. This diaphragm delivers reliable performance under frequent cycle conditions, maintaining chamber isolation, resisting chemical attack, and ensuring the seal between the air and fluid sides remains uncompromised. By using this OEM‑specified diaphragm, you restore the pump’s designed stroke, sealing behaviour, and durability — critical for minimizing downtime and maintaining efficient operations.
Key Features
- Viton (fluoroelastomer) material at FDA rating — excellent chemical resistance and elasticity property
- Manufactured to OEM tolerances for the 1040 series, ensuring correct fit, stroke and sealing integrity
- Suitable for frequent cycling typical of high‑throughput AODD pump applications, reducing maintenance downtime
- Provides robust one‑way chamber motion, fluid isolation and helps prevent air intrusion or fluid cross‑contamination
- Ideal for fluid‑handling systems requiring sanitary or food‑grade elastomer compatibility while maintaining high performance

Usage Notes
- Ensure the pump is fully depressurized and isolated from fluid before removing or installing the diaphragm to prevent injury or damage.
- Inspect the diaphragm chamber, seal surfaces and fluid/air interfaces for wear, corrosion or damage prior to installation.
- Clean all mating surfaces and align the diaphragm correctly to maintain proper stroke, sealing and pump performance.
- After installation, conduct a test cycle under normal operating conditions to verify correct chamber movement, fluid displacement and absence of leaks or air infiltration.
- Replace the diaphragm if there are any signs of cracking, extrusion, permanent deformation, leakage or if scheduled maintenance interval is reached — failure to do so may lead to more extensive pump service.
