Key Features

• Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original pipe, ensuring correct flow characteristics and connection integrity specific to the RW-1800 water system.
• Direct-Fit Replacement — Engineered to align with existing fittings and mounting points on RW1810 rollers, so installation is straightforward without reworking any connections.
• Confirmed RW1810 Fitment — Verified for the Multiquip RW1810 RAMMAX ride-on roller series, so you can order with confidence knowing this is the correct part for your machine.
• Sustained Water Distribution — A fully intact upper water pipe keeps the roller drum properly wetted during asphalt and compaction passes, preventing material pickup and maintaining a clean drum surface.
• Verified Part Number — Multiquip part number 50045 is traceable through the OEM parts catalog, eliminating guesswork when cross-referencing your machine's parts list.

The upper water pipe on a ride-on roller is part of the drum wetting system, which delivers a continuous flow of water to the drum surface during compaction operations. Keeping the drum wet prevents hot asphalt or other paving material from sticking to the roller, which protects the surface finish and maintains compaction efficiency. A cracked, blocked, or leaking upper water pipe disrupts this flow, leading to material buildup on the drum and uneven compaction results — making timely replacement essential to keeping work on schedule.
