The Multiquip A400321501 Stopper is a genuine OEM component designed for GB4000 and GB2000 balloon systems. Sourced directly from Multiquip, this part meets the exact specifications of the original component installed at the factory. Confirmed fitment includes GB4000 units and GB2000 units with serial number G3000001 and up, so verify your serial number before ordering to ensure a correct match.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional specifications for the stopper application, ensuring the part seats and functions exactly as intended.
- Direct-Fit Installation — Engineered to drop into the existing mounting position without alteration, using the same attachment points as the original component.
- Confirmed Fitment — Compatible with GB4000 and GB2000 (S/N G3000001 and up) balloon systems; always cross-reference your serial number to confirm applicability.
- Maintains Controlled Movement — A correctly functioning stopper limits travel and prevents over-extension within the assembly, preserving alignment and protecting surrounding components from impact damage.
- Operational Safety Relevance — In balloon system applications, a worn or missing stopper can allow uncontrolled movement that risks component contact and structural stress — replacing it promptly keeps the system operating within its designed range of motion.
A stopper is a mechanical limit component that controls and restricts the travel range of a moving part within an assembly. It absorbs or blocks movement at a defined endpoint, preventing contact between components that could cause wear, misalignment, or structural damage. When a stopper deteriorates or fails, the system loses its defined travel boundary, leading to uncontrolled motion, accelerated wear on adjacent parts, and potential damage to the broader assembly.
