Multiquip 11978 Plastic 4 Barb 3 Barb Fitting

The Multiquip 11978 Plastic 4 Barb 3 Barb Fitting is a genuine OEM component designed for LD6, LD6SL, and LD60 ride-on power trowels, as well as the RX1575 walk-behind roller. Sourced directly from Multiquip, this fitting matches the original specification for a straight-forward, correct installation. It is the exact part your machine was built with, ensuring proper fluid routing and a secure barbed connection. Confirm your model code against the fitment list before ordering to ensure compatibility.

Key Features

• Genuine OEM Construction — Molded to the original barb profile and material specification, delivering the same fit and flow characteristics as the part it replaces.
• Dual Barb Sizing — The 4-barb-to-3-barb configuration connects two different diameter hoses or lines exactly as the original fluid routing requires.
• Confirmed Fitment — Directly compatible with LD6, LD6SL, and LD60 ride-on power trowels and the RX1575 walk-behind roller.
• Secure Hose Retention — The barbed design grips hose ends firmly, maintaining a leak-free connection even under normal operating vibration and pressure.
• Direct Drop-In Replacement — Matches the original mounting and connection points, so installation requires no trimming, adapting, or additional hardware.

A barbed fitting serves as the junction point between two hose lines within the machine's fluid routing system, allowing fluid to pass from one line to another while keeping both hoses locked securely in place. The stepped 4-barb-to-3-barb design on this fitting accommodates two different hose diameters at a single connection point. When a plastic barbed fitting cracks, splits, or loses its grip on a hose end, the result is a fluid leak that can compromise system pressure and lead to operational issues — making timely replacement important for keeping the machine running as intended.
