Wacker Neuson 5000028071 Coupling 3 Hose Shank Ext Thd

The Wacker Neuson Coupling 3 Hose Shank Ext Thd is a genuine OEM hose connection fitting designed for PT3, PT3A, PT3H, PT3V, PT3Y, PS3, PST3, PG3, PDT3, and PDI3A series pumps. As a direct OEM replacement, this coupling is manufactured to the same specifications as the original, ensuring a secure, leak-free hose connection every time. It fits an extensive range of 75mm/3-inch centrifugal trash pumps and submersible pump models across multiple Wacker Neuson product lines. If you are servicing a PT3 or PS3 series pump and need to restore a damaged or worn hose port, part number is the correct OEM solution.

Key Features

• Genuine OEM Hose Port Integrity — Manufactured to Wacker Neuson's original dimensional tolerances, ensuring full thread engagement and a pressure-rated seal at the hose connection point.
• External Thread Design — The external threaded shank interfaces directly with standard pump discharge hose fittings, allowing straightforward installation without adapters.
• Broad PT3 and PS3 Series Coverage — Confirmed fitment across PT3, PT3A, PT3H, PT3V, PT3Y, PS3-1503, PS3-2203, PS3-3703, PS3-5503, PST3-750, PG3, PDT3, and PDI3A pump models.
• Maintains Full Flow Capacity — A correctly seated coupling keeps the discharge path unrestricted; a cracked or cross-threaded coupling causes pressure loss, leaks, and reduced pump output on the jobsite.
• Fuel and Fluid Safety Relevance — On pump applications, a compromised hose coupling can result in uncontrolled discharge of contaminated water or hazardous fluids; replacing a damaged coupling promptly keeps the discharge path contained and controlled.

The hose shank coupling serves as the threaded connection point between the pump body's discharge port and the discharge hose assembly. It channels pressurized flow out of the pump and into the hose line, and the external thread profile locks the hose fitting in place under operating pressure. When this coupling becomes cracked, corroded, or stripped, the threaded joint can no longer hold a pressure-tight seal, leading to leaks at the discharge connection, loss of pump prime, and reduced overall flow. Replacing it with the correct OEM part restores the original connection geometry and ensures the pump operates at its rated discharge capacity.
