Multiquip 49903 2" MNPT x 2" Barb Fitting

The Multiquip 49903 is a genuine OEM 2" MNPT x 2" Barb Fitting designed for Multiquip Water Trailer series equipment, including the WT5HP, WTE5HP, WT5HPSG, WT5C, WTE5C, and WT5CSG models. As a direct OEM replacement, this fitting is manufactured to the same specifications as the original component, ensuring a secure, leak-free connection in your water trailer's plumbing system. DHS Equipment supplies this part directly, so you can be confident you are receiving an authentic Multiquip component with the correct thread and barb dimensions. Verify your model against the fitment list above before ordering to confirm compatibility.

Key Features

• Genuine OEM Thread and Barb Dimensions — Manufactured to exact 2" MNPT male thread and 2" barb specifications, eliminating the guesswork of aftermarket sizing mismatches in high-flow plumbing applications.
• Direct-Connect Replacement — Threads directly into the existing female NPT port and accepts standard 2" hose barb connections, allowing a straightforward swap with no rework to surrounding fittings or hose assemblies.
• Broad Water Trailer Fitment — Confirmed for WT5HP, WTE5HP, WT5HPSG, WT5C, WTE5C, and WT5CSG Water Trailer models, covering both centrifugal pump and high-pressure pump variants in the Multiquip Water Trailer lineup.
• Leak-Free Flow Performance — A properly seated fitting at this diameter maintains full water flow capacity through the trailer's system; a cracked, stripped, or corroded fitting will cause pressure loss, leaks, and potential hose blowoff under load.
• Pressure System Safety — In a water trailer plumbing circuit, a compromised fitting can lead to uncontrolled discharge or hose separation; using the correct OEM-spec component ensures the connection holds under rated operating pressure.

A 2" MNPT x 2" Barb Fitting serves as a transition connector between the threaded ports of a pump, valve, or manifold and a flexible hose in a water trailer's plumbing circuit. The male NPT threads create a tapered, pressure-rated seal when threaded into a female port, while the barbed end grips the interior of a hose, holding it in place under flow pressure. When this fitting cracks, corrodes, or strips, the connection between the rigid plumbing and the flexible hose is compromised, resulting in leaks, reduced flow, or complete hose separation during operation.
