The Bomag 05850251 One Way Restrictor is a genuine OEM component designed for BC-series refuse and landfill compactors, including the BC 571 RB, BC 671 RB, BC 671 RS, BC 771 RB, and BC 771 RS. Sourced directly from Bomag, this part meets the exact specifications of the original component it replaces. This one way restrictor installs into the hydraulic circuit of these compactors as a direct replacement, with no adaptation needed to match the original configuration. If you're running BC-series refuse compactors and need a confirmed OEM fit, part number 05850251 is the correct replacement to specify.
Key Features
- Genuine OEM Hydraulic Precision — Manufactured to Bomag's original flow-control specifications, ensuring the restrictor passes fluid in one direction at the correct rate for consistent hydraulic system behavior.
- Direct Drop-In Replacement — Engineered to match the original port sizing, thread specification, and body dimensions of the factory-installed unit for a straightforward swap.
- Broad BC-Series Coverage — Fits the BC 571 RB, BC 671 RB, BC 671 RS, BC 771 RB, and BC 771 RS refuse and landfill compactors, covering multiple configurations across the lineup.
- Protects Hydraulic Circuit Integrity — A correctly functioning one way restrictor prevents uncontrolled flow reversal and pressure spikes that can accelerate wear on downstream hydraulic components.
- Verified Bomag Part Number — Ordering by part number 05850251 eliminates substitution errors and confirms you're receiving the correct component for your machine.
A one way restrictor is a hydraulic flow-control fitting that allows fluid to pass freely in one direction while metering or blocking flow in the opposite direction. In a refuse and landfill compactor, this component is used to regulate the speed or force of a hydraulic actuator on one stroke while allowing unrestricted return travel, protecting the circuit from pressure surges and ensuring smooth, controlled operation of the compaction or steering functions it serves. When this restrictor wears, becomes clogged, or fails, the affected circuit can exhibit erratic movement, loss of control authority, or excessive heat buildup — all of which place additional stress on pumps, valves, and cylinders throughout the system.
