The flexible elastomer “spider” that sits between the two metal jaws of Flow’s pump motor coupling. At every pressure stroke it compresses slightly, absorbing torsional shock from the intensifier crank while keeping the hubs perfectly in step, so your 60k psi ESL or Classic pump stays smooth, quiet and aligned.
The OEM Difference
No one tests like Flow. Flow OEM parts deliver unmatched precision, durability, and safety. Every component is engineered to outperform and outlast the rest.
