The Multiquip 03780800 Hose Nipple 2G40 Hatz is a genuine OEM replacement designed for RW1404, RW1404MR, and RW1504HF RAMMAX walk-behind rollers. As a direct-source OEM component, 03780800 is manufactured to the same specification as the original part, ensuring a correct, trouble-free installation in Hatz-powered roller applications. Fitment includes RW1404MR units from S/N 326075 and up, RW1504HF units up to S/N, and standard RW1404 models. Sourcing the correct OEM nipple means your roller's cooling or fluid routing system stays sealed, leak-free, and performing as intended.
Key Features
- Genuine OEM Construction — Produced to original Hatz engine integration specs, ensuring correct thread form, bore diameter, and material grade for a leak-free fluid connection.
- Direct-Fit Installation — Matches the original hose port configuration on 2G40 Hatz engines, so the nipple seats and seals correctly without rework or adapter fittings.
- Confirmed Fitment — Compatible with RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) RAMMAX walk-behind rollers.
- Fluid System Integrity — A sound hose nipple keeps coolant or fluid routing sealed under operating pressure; a cracked or failed nipple leads to fluid loss and potential engine overheating.
- Verified OEM Part Number — Ordering by exact part number 03780800 eliminates the guesswork of cross-referencing and confirms you receive the correct component for your serial number range.
A hose nipple is a threaded or barbed fitting that forms the rigid connection point between an engine's fluid port and a flexible hose in the cooling or fluid delivery circuit. On Hatz 2G40-powered equipment like the RW1404 and RW1504HF RAMMAX rollers, this fitting directs coolant or hydraulic fluid through the system at consistent pressure. When a nipple cracks, corrodes, or strips at the threads, the seal is broken — leading to fluid leaks, pressure drop, and potential engine damage if left unaddressed. Replacing it promptly with the correct OEM part restores the integrity of the fluid circuit and keeps the roller operating within its designed thermal and hydraulic parameters.
