Multiquip AT377287 Hose Barb

The Multiquip AT377287 Hose Barb is a genuine OEM component designed for the DCA-series Ultra-Silent diesel generator line, including DCA70SSJU4F, DCA150SSJU4F, DCA180SSJU4F, DCA220SSJU4F, and DCA300SSJU4F models. As a direct OEM replacement, AT377287 is sourced to the same specification as the original production part, ensuring a correct, secure connection within the generator's fluid routing system. Confirm your model code against the fitment list before ordering to ensure this is the right hose barb for your unit. DHS Equipment stocks genuine Multiquip OEM parts to keep your generator running as designed.

Key Features

• Genuine OEM Spec Fitting — Manufactured to the same dimensional and material tolerances as the original production part, ensuring a leak-free, pressure-rated connection in the fluid circuit.
• Direct Drop-In Installation — Threads and barb dimensions match the original port and hose ID exactly, so the fitting seats and seals without rework or adapters.
• Broad DCA-Series Compatibility — Fits DCA70SSJU4F, DCA150SSJU4F, DCA180SSJU4F, DCA220SSJU4F, and DCA300SSJU4F Ultra-Silent generator models across multiple build variants.
• Maintains Fluid System Integrity — A correctly functioning hose barb keeps coolant or fluid lines firmly seated under vibration and operating pressure; a worn or cracked barb risks hose slippage and fluid loss.
• Fuel and Coolant System Safety — Proper sealing at every hose connection is critical in diesel generator fluid circuits; a failed barb fitting can lead to leaks that create fire risk or engine overheating.

A hose barb is a small but critical fitting that creates a secure mechanical connection between a rigid port or line and a flexible hose in the generator's fluid routing system — whether coolant, fuel, or an auxiliary circuit. The barbed profile grips the interior of the hose under clamp pressure, preventing the hose from slipping off under vibration or line pressure during operation. When a hose barb cracks, strips, or corrodes, the hose connection becomes unreliable, which can result in fluid leaks, loss of cooling capacity, or engine damage — making timely replacement essential to sustained generator output.
