The Wacker Neuson is a genuine OEM O-Ring 98x2 designed for the RD7H, RD7Heh, RD7Yeh, RD7Af, RD7Hf, RD7Hehf, RD7Yehf, RD7Hfb, RD7Hehfb, RD7Yehfb, RD7Afb, and RD10Yehf series double drum rollers. As a direct Wacker Neuson OEM part, is manufactured to the exact material grade and dimensional tolerances specified for these machines, ensuring a correct drop-in fit without any guesswork. This O-Ring 98x2 covers an extensive range of RD7 and RD10 series configurations — including HRC, LRC, and standard variants — so you can confirm compatibility across your fleet with a single part number.
Key Features
- Correct Compression Seal Geometry — Manufactured to the exact 98x2 mm cross-section spec, ensuring consistent radial compression and leak-free seating in the designated bore.
- Genuine OEM Material Grade — Sourced directly from Wacker Neuson, this O-ring uses the approved elastomer compound rated for the hydraulic fluid temperatures and pressures found in these roller systems.
- Direct Replacement Installation — Seats directly into the existing groove with no trimming, shimming, or adaptation — a straight swap during scheduled maintenance or unplanned seal replacement.
- Broad RD7 and RD10 Series Coverage — Fits RD7H, RD7Heh, RD7Yeh, RD7Af, RD7Hf, RD7Yehf, RD7Hfb, RD7Yehfb, RD7Afb HRC, and RD10Yehf LRC configurations across HRC and LRC variants.
- Protects Against Fluid Intrusion and Leakage — A correctly seated O-ring keeps hydraulic or lubricating fluid contained within the circuit; a degraded seal leads to fluid loss, contamination ingress, and accelerated component wear.
An O-ring is a precision-molded loop of elastomer that sits in a machined groove between two mating surfaces, forming a pressure-tight seal that prevents fluid or lubricant from escaping the assembly. In compaction equipment like the Wacker Neuson RD7 and RD10 series rollers, O-rings are critical in hydraulic circuits, drum drive systems, and bearing housings where maintaining correct fluid pressure directly affects machine performance and drive response. When an O-ring degrades — through heat cycling, chemical exposure, or mechanical wear — it loses its ability to maintain a seal, resulting in fluid weeping, loss of hydraulic pressure, and potential damage to surrounding components if left unaddressed.
