Graco 15B492 FDA 2150 Buna Ball – Product Details & Compatibility
Compatible Machines
The Graco 15B492 FDA 2150 Buna Ball is intended for use in check‑valve assemblies of Graco sanitary diaphragm pumps, especially the 2150 series, where a food‑grade or hygienic‑rated elastomer is required. It is ideal for:
- Graco Husky 2150 (FDA or sanitary version) diaphragm pumps
- Any pump check‐valve module specified for a Buna‑N ball in FDA‑rated service
- Replacement or maintenance kits in high‐cycle, sanitary fluid‑handling systems where food, beverage or personal care standards apply
Product Overview
The Graco 15B492 FDA 2150 Buna Ball is an OEM‑grade check‑valve ball made from Buna‑N (nitrile) elastomer, designed to meet FDA requirements for the 2150 series pumps. It delivers dependable one‑way sealing and back‑flow prevention in demanding sanitary or food‑contact environments. Built to Graco’s original specifications, this ball supports frequent cycling, moderate chemical exposure, and ensures consistent flow performance with minimal leakage and downtime.
Key Features
- Buna‑N (nitrile) elastomer material compliant with sanitary and food‑grade applications
- Engineered to OEM tolerances for the 2150 series to ensure correct fit and optimal performance
- Designed for frequent check‑valve cycling — reducing maintenance and downtime in high‑use applications
- Provides reliable one‑way flow control and prevents back‑flow in check‑valve systems
- Ideal for systems where food‑grade, hygienic or regulated fluid handling requires certified components

Usage Notes
- Always ensure the pump or system is fully depressurized before removing or replacing the ball to avoid injury and damage.
- Before installation, inspect the ball‑seat bore and mating surfaces for wear, corrosion or contamination to avoid seal failure.
- Clean all mating components, align correctly and install the ball per OEM instructions to achieve optimal performance.
- After installation, run a trial cycle under normal operating conditions to confirm sealing integrity and flow behaviour.
- Replace the ball immediately if signs of cracking, deformation, extrusion, surface degradation or leakage are visible to maintain system reliability.
Frequently Asked Questions
It serves as the sealing element in the check‑valve, allowing fluid to flow in the intended direction and preventing reverse flow or leakage.
While alternate materials may fit, using the OEM‑specified Buna‑N ball ensures the design sealing behaviour, fluid compatibility and service life intended for the sanitary 2150 series.
Replace it if you detect leaks, reduced check‑valve performance, visible damage such as cracks or deformation, or any indication the elastomer has degraded.
