The Multiquip 50303000 is a genuine OEM Hose Connection 2G40 Hatz designed for RAMMAX walk-behind rollers including the RW1404, RW1404MR, and RW1504HF series. As a direct OEM replacement, the 50303000 is manufactured to the same specifications as the original component, ensuring a correct, hassle-free installation. Fitment covers RW1404MR units at S/N 326075 and up and RW1504HF units up to S/N, so confirm your serial number before ordering. DHS Equipment stocks genuine Multiquip parts to keep your roller running as intended.
Key Features
- Genuine OEM Construction — Produced to Multiquip's original material and dimensional standards for the Hatz 2G40 engine cooling circuit, not a generic substitute.
- Serial-Number-Specific Fitment — Confirmed for RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N 1534188); verify your serial number to ensure correct application.
- Direct Drop-In Installation — Matches the original hose routing and connection points on the Hatz engine, so no cutting, adapting, or re-routing is needed.
- Coolant System Integrity — A properly seated hose connection maintains sealed coolant flow to the Hatz 2G40 engine; a cracked or loose connection leads to coolant loss, overheating, and unplanned shutdowns on the drum.
- Broad RW-Series Coverage — Compatible across the RW1404, RW1404MR, and RW1504HF RAMMAX roller models, making it a practical stocking part for fleets running multiple units.
The hose connection serves as the sealed interface between coolant hoses and the Hatz 2G40 engine's cooling circuit on RAMMAX walk-behind rollers. It directs coolant flow through the engine to regulate operating temperature and prevent heat buildup during compaction passes. When this fitting cracks, warps, or loses its seal, coolant escapes the circuit — leading to overheating, potential engine damage, and forced downtime on the jobsite.
