The Multiquip 50125-04 is a genuine OEM Plastic Quick Disconnect Knob designed for BPX, CV1A, CV2A, CV2B, CV3A, and CV3B series concrete vibrators. As a direct OEM replacement, the 50125-04 is manufactured to the same specification as the original component, ensuring a correct, trouble-free installation with no guesswork on fit or function. Sourced directly through authorized Multiquip supply channels, this part is the same knob that ships on new machines — giving you confidence that you are restoring your vibrator to its original operating condition.
Key Features
- Genuine OEM Construction — Molded to the original material grade and dimensional tolerances required for a quick-disconnect application, so the knob seats, locks, and releases the way it was designed to.
- Direct Drop-In Replacement — Matches the original mounting interface on BPX, CV1A, CV2A, CV2B, CV3A, and CV3B vibrators, so the knob threads or snaps into place exactly as the factory unit did.
- Broad Vibrator Series Fitment — A single part number covers the BPX backpack flex-shaft vibrators and the CV1A, CV2A, CV2B, CV3A, and CV3B concrete vibrator models, making cross-fleet servicing straightforward.
- Smooth Disconnect Action Restored — A worn or cracked knob makes separating the flex shaft from the power unit difficult and can cause unintended disengagement mid-pour; replacing it brings the quick-disconnect mechanism back to full, positive operation.
- Operator Safety Relevance — A secure, fully functional quick-disconnect knob is essential for safely coupling and decoupling flex-shaft components — a damaged knob risks accidental separation under vibration load.
The Plastic Quick Disconnect Knob is the user-operated interface that locks the flex shaft to the concrete vibrator power head and releases it for transport, blade changes, or service. When engaged, it holds the connection rigid so vibration energy transfers efficiently down the shaft to the head without play or wobble. When the knob cracks, strips, or becomes difficult to turn, the coupling can slip or fail to release cleanly, interrupting the pour and potentially creating a hazard for the operator.
