Graco 15B267 2150 Diaphragm Pump Ball Seat – Product Details & Compatibility
Compatible Machines
The Graco 15B267 2150 Diaphragm Pump Ball Seat is intended for use in the Graco Husky 2150 series air‑operated diaphragm pumps where the check‑valve section uses a ball‑and‑seat assembly with Buna‑N (nitrile) or equivalent elastomer seating material.
- Husky 2150 diaphragm pumps and fluid‑handling modules using the 2150 ball‑and‑seat check‑valve configuration
- Pump assemblies undergoing maintenance or rebuilds where the ball‑seat component is replaced to restore unidirectional flow and sealing performance
- Applications in general industrial fluid transfer where reliability and correct seat material are critical to prevent back‑flow or leakage
Product Overview
The Graco 15B267 Ball Seat 2150 is an OEM‑specified check‑valve seating component engineered for the Husky 2150 pump. It provides the correct elastomer interface between the check‑valve ball and the housing, ensuring effective sealing, preventing reverse flow, and helping maintain pump efficiency under heavy cycling.
Key Features
- OEM replacement seat designed specifically for the Husky 2150 ball check‑valve system
- Certain material construction (Buna‑N or equivalent elastomer) suitable for the specified check‑valve environment
- Ensures consistent seal integrity even under high‑cycle, high‑pressure pump conditions
- Easy to install as part of rebuilds or maintenance operations without replacing the full valve assembly
Technical Specifications
| Part Number | 15B267 |

Usage Notes
- Always relieve system pressure and isolate fluid lines before servicing the check‑valve section.
- Install the OEM part 15B267 to ensure proper geometry, material compatibility and sealing performance; aftermarket substitutions may degrade pump reliability.
- Inspect the mating ball, seat bore and surrounding surfaces for wear, damage or debris before installing the new seat.
- After installation, run the pump under normal operating conditions and monitor for signs of reverse flow, leakage or reduced pressure recovery to confirm the check‑valve is functioning correctly.
Frequently Asked Questions
It provides the critical sealing surface for the check‑valve ball in the Husky 2150 pump, ensuring unidirectional flow and preventing reverse flow or pump inefficiency.
While a physically compatible replacement might fit, using the OEM 15B267 ensures the correct elastomer material, dimensional tolerances and seal performance needed in the Husky 2150 check‑valve environment.
Replace this seat if you observe worn or flattened seating surfaces, visible damage to the elastomer, frequent reverse flow or increased leakage despite proper assembly of other components.
