The Wacker Neuson is a genuine OEM Elbow Barbed Hose Fitting designed for RD12, RD16, CB14B, RS600, and RS800 series rollers and compactors. As a direct OEM replacement, this fitting is sourced to the original specification and drops into place without modification. Fitment spans a wide range of Wacker Neuson tandem rollers, single-drum vibratory rollers, and soil and asphalt compaction machines, making part number a high-demand service item across multiple equipment lines.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original barb geometry and material spec, ensuring a secure, leak-free hose connection under operating pressure and vibration.
- Direct-Fit Replacement: — Matches the original elbow angle and barb diameter so the hose seats correctly without reworking the surrounding plumbing.
- Broad Fitment Coverage: — Compatible with RD12A-90, RD12-90, RD16-90, RD16-100, CB14B-900, CB14B-1000, RS600, RS600A, RS800, RS800A, RSS800A, and RS800V series machines.
- Maintains Fluid Circuit Integrity: — A correctly seated barbed elbow prevents water or hydraulic fluid weeping at hose junctions, keeping the water system or hydraulic circuit flowing at full capacity.
- Vibration-Resistant Barb Retention: — The barbed profile grips the hose firmly, resisting the constant vibration inherent to compaction equipment that can loosen push-fit or poorly matched fittings over time.
A barbed elbow hose fitting routes flexible hose around a directional change within the machine's fluid circuit — most commonly the water sprinkler system used to prevent asphalt from sticking to the drums on tandem rollers. The angled elbow body redirects flow while the barbed stem grips the inside wall of the hose to form a seal without additional clamp force at the barb itself. When this fitting cracks, deforms, or pulls free of the hose, fluid flow to the drums is interrupted, which can cause asphalt adhesion, uneven compaction passes, and accelerated drum wear.
