Armstrong Packaged Coupling Insert Pipe Fitting

The Armstrong Packaged Coupling Insert is a replacement pump coupler insert (also called a coupling insert or flexible coupler insert) for Armstrong Fluid Technology pumps. It is the replaceable element in the pump coupling. It links the drive motor to the pump shaft and helps keep the drivetrain running smoothly.

Key Features:

• Replacement insert for Armstrong pump couplings, made to Armstrong Fluid Technology's part specifications
• Part of the coupling that transmits motor power to the pump shaft
• Helps absorb vibration, which protects pump and motor bearings from the extra wear a worn coupling causes
• Suited to HVAC, plumbing, and other fluid-handling pump applications
• Available in multiple insert sizes, each with its own part number

Coupling inserts wear over years of continuous operation. Replacing a worn insert helps maintain quiet, reliable pump performance and extends the service life of the pump and motor. Choose the insert size that matches your pump model and coupling.
