Armstrong 875000-804 Packaged Coupling Insert Pipe Fitting - 7JE

The Armstrong 875000-804 is a packaged coupling insert designed for flexible coupling assemblies in commercial and industrial pump applications. This 7JE size insert is a genuine Armstrong replacement part compatible with Series 4030 pumps and other Armstrong pump models requiring this coupling size.

Key Features:

• 7JE size Woods-style flexible coupling insert
• EPDM rubber construction for durability and chemical resistance
• No metal-to-metal contact for clean, quiet operation
• No lubrication required for maintenance-free performance
• Slides into position between coupling flanges for easy installation
• Absorbs shock loads and compensates for minor misalignment

This coupling insert is a critical wear component that connects the pump shaft to the motor shaft while allowing for slight angular and parallel misalignment. Regular inspection and replacement of worn coupling inserts helps prevent motor and bearing damage, ensuring reliable pump operation in heating, cooling, and process water systems.
