The Wacker Neuson Ring Seal 8 X 12 is a genuine OEM component designed for a wide range of Wacker Neuson compaction and cutting equipment, including DPU 4045H, DPU 5045H, DPU 2430F, DPU 2440F, DPU 2450F, DPU 2870, DPU 2950, DPU 2960, DPU 2970, DPU 7060, DPS2040, DPS2050, DPS3050, DPS3060, RD25, RS800H series machines, and the DFS 90 floor saw. As a genuine Wacker Neuson part, the is manufactured to the exact material and dimensional specifications required to maintain a proper hydraulic or fluid seal in your machine. It drops in as a direct replacement with no guesswork, making it the trusted choice for service technicians and equipment owners who need the job done right the first time. Confirm your model number against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Material Integrity — Manufactured to Wacker Neuson's exact elastomer and dimensional specifications, ensuring the correct compression set and sealing performance for hydraulic and fluid system applications on these machines.
- Direct Hydraulic System Fit — Sized precisely at 8 x 12 mm to seat correctly in its designated port or fitting, eliminating the risk of improper seating that leads to fluid bypass or leakage.
- Broad Fitment Across Compaction and Cutting Families — Compatible with DPU reversible vibratory plate compactors, DPS single-direction vibratory plates, RD25 tandem rollers, RS800H single-drum rollers, and the DFS 90 powered floor saw.
- Leak Prevention Where It Counts — A correctly seated ring seal maintains system pressure integrity; a degraded or improperly sized seal allows fluid loss that can lead to erratic compaction force or hydraulic system damage.
- Fluid System Safety Compliance — Using the correct OEM-specified seal prevents uncontrolled fluid weepage at joints and fittings, supporting safe operation and reducing environmental contamination risk on the worksite.
A ring seal — sometimes called an O-ring or sealing ring — creates a fluid-tight barrier between mating components in hydraulic circuits, oil passages, or fluid fittings. In compaction and cutting equipment, these seals are subjected to continuous vibration, pressure cycling, and temperature variation, all of which gradually degrade the seal material over time. When a ring seal fails, fluid bypasses the joint, causing pressure loss, external leakage, or contamination of surrounding components — any of which can compromise the machine's hydraulic output or trigger premature wear elsewhere in the system. Replacing a worn ring seal promptly with the correct part, such as the Wacker Neuson 5000012491, restores system integrity and keeps hydraulic-driven functions performing as intended.
