Graco 15B487 FDA Viton Ball for Husky 1040 Pump – Product Details & Compatibility
Compatible Machines
The Graco 15B487 FDA Viton Ball is designed for use in the check‑valve assemblies of the Husky 1040 series diaphragm pumps and other compatible Graco fluid‑handling units that specify a ball component made from FDA‑compliant Viton® elastomer. It is ideal for applications requiring reliable sealing, chemical resistance and adherence to sanitary standards.
- Graco Husky 1040 diaphragm pumps in sanitary, food, beverage or chemical‑transfer applications
- Pump assemblies where the ball check valve must maintain integrity under frequent cycling and fluid exposure
- Maintenance or service kits for high‑cycle industrial systems requiring genuine OEM balls for performance and longevity
Product Overview
The Graco 15B487 FDA Viton Ball is an OEM‑specified ball component engineered from fluorocarbon elastomer (Viton®/FKM) compliant with food‑grade requirements. It acts as the sealing interface within the pump’s check‑valve system, preventing backflow, ensuring unidirectional flow and maintaining system efficiency even in harsh environments.
Key Features
- Constructed from FDA‑compliant Viton®/FKM material for outstanding chemical resistance and durability
- Precisely manufactured to OEM tolerances for seamless fit and reliable performance in the check‑valve assembly
- Optimised to handle frequent cycling and exposure to fluids, solvents or coatings without degradation
- Allows maintenance or retrofit without replacement of the entire valve, helping reduce downtime and cost

Usage Notes
- Depressurise the pump and isolate fluid lines before servicing the valve ball.
- Inspect the ball seating surface, bore and mating components for wear, debris or damage.
- Install the ball ensuring correct orientation, clean mating surfaces and proper alignment.
- After installation, run a brief test cycle to verify sealing integrity and absence of back‑flow or leakage.
- Replace the ball when you observe surface wear, cracking, chemical attack or leakage in the check‑valve system.
Frequently Asked Questions
It serves as the sealing component in the check‑valve assembly of the pump, ensuring one‑way flow and preventing back‑flow while resisting chemical, thermal and cycle stresses.
While some non‑OEM balls may fit physically, using the OEM 15B487 ensures correct material (FDA‑compliant Viton®), precise tolerances and reliable long‑term performance as the pump was designed.
Replace when the ball shows signs of wear, cracking, swelling, or chemical attack, or if the pump begins to leak, lose efficiency, or fail to maintain proper check‑valve operation.
