The Multiquip RE321504 Hose Barb is a genuine OEM component designed for DCA300SSJU4F series Super-Silent diesel generators, including the DCA300SSJU4F, DCA300SSJU4F2, DCA300SSJU4F3, and DCA300SSJU4F3PD models. As a direct OEM replacement, the RE321504 meets the exact specifications of the original part, ensuring a secure, leak-free connection within the generator's fluid routing system. This hose barb is compatible across both standard and 60Hz-designated DCA300SSJU4F variants, making it the right choice for technicians servicing this generator family. Source it with confidence from DHS Equipment as an authorized Multiquip parts supplier.
Key Features
- OEM-Matched Material and Geometry — Manufactured to the original barb profile and material spec, ensuring the correct grip and seal on mating hose ends without distortion or leakage.
- Direct Installation Fit — Installs directly into the existing fluid line port with no rework to surrounding hose or fittings, matching the thread form and barb diameter of the original.
- Broad DCA300SSJU4F Series Coverage — Confirmed fitment across DCA300SSJU4F, DCA300SSJU4F2, DCA300SSJU4F3, and DCA300SSJU4F3PD variants, including 60Hz-designated configurations.
- Leak-Free Fluid Routing — A correctly seated hose barb maintains consistent flow and pressure in the generator's coolant or fluid circuit; a worn or cracked barb risks fluid loss, overheating, or unplanned shutdown.
- Genuine Multiquip OEM Part — Supplied under part number RE321504 directly from the Multiquip parts network, ensuring traceability and confidence in specification accuracy.
A hose barb is a small but critical fitting that connects flexible hose sections within a machine's fluid routing system — typically coolant, fuel, or auxiliary lines. It works by gripping the inner wall of the hose as it seats, forming a tight mechanical seal that prevents fluid from escaping under pressure or vibration. When a hose barb cracks, corrodes, or loses its barbed profile, the connection becomes prone to seeping or outright leaks, which can lead to coolant loss, erratic engine temperatures, or contamination of surrounding components in a working generator.
