The Wacker Neuson is a genuine OEM Nipple Fitting designed for the PT3 series of 75mm/3-inch self-priming centrifugal trash pumps, including the PT3A, PT3H, PT3Y, PT3V, and PTK3 pump kit configurations. As a factory-sourced component, the is manufactured to the same specifications as the original part it replaces, ensuring a direct, hassle-free installation in your pump system. This fitting is an essential fluid-path component that must seal correctly to maintain pump output and prevent leaks at the connection point. If you're servicing a PT3A, PT3H, or any variant in the PT3 family, the is the correct OEM replacement to keep your pump running at full capacity.
Key Features
- Genuine OEM Thread and Dimensional Accuracy — Manufactured to the same thread pitch, diameter, and material spec as the original, ensuring a leak-free seal at every connection point.
- Direct-Fit Replacement — Engineered to drop into the same port location as the factory fitting, with no reworking of the pump housing or adjacent fittings required.
- Broad PT3 Series Compatibility — Confirmed fitment across PT3A, PT3H, PT3Y, PT3V, PT3 (without engine), and PTK3 pump kit configurations.
- Maintains Pump Flow Integrity — A correctly seated nipple fitting preserves the sealed fluid circuit inside the pump; a cracked or cross-threaded fitting can cause pressure loss, air ingestion, and reduced discharge performance.
- Fuel and Fluid System Compliance — As a wetted fluid-path component, using the correct OEM fitting ensures material compatibility with pump media and proper torque engagement — critical for safe, leak-free operation.
A nipple fitting is a short threaded connector used to join two sections of pipe, hose, or ported hardware within the pump's fluid circuit. In a centrifugal trash pump like the PT3 series, these fittings form part of the sealed pathway through which water and suspended solids travel from the inlet to the discharge port. When a nipple fitting becomes damaged, corroded, or improperly seated, it can allow air to enter the suction side of the pump or cause leaks on the discharge side — both of which degrade pumping efficiency and can lead to loss of prime. Replacing a worn or failed fitting promptly with the correct OEM part restores the integrity of the fluid path and protects downstream hose connections from undue stress.
