The Wacker Neuson is a genuine OEM Nipple Fitting 4 Bspt X 3.12 designed for the PTS4V centrifugal trash pump and PTK4 pump kit series. As a direct factory-sourced component, the is manufactured to the same specifications as the original part, ensuring a proper connection within the pump's fluid-handling circuit. This fitting is the correct replacement for PTS4V and PTK4 applications where thread integrity and leak-free sealing are essential to sustained pump performance.

Key Features

  • Genuine OEM Thread Specification — Machined to the exact BSPT thread form and dimensional tolerances required for a pressure-tight seal in the pump circuit.
  • Direct-Install Replacement — Threads directly into the existing port on PTS4V and PTK4 pump housings with no reworking of mating surfaces.
  • Correct Fitment for PTS4V and PTK4 Series — Sourced specifically for the 100mm/4-inch centrifugal trash pump and PTK4 pump kit configurations.
  • Leak-Free Fluid Path — A properly seated nipple fitting maintains full system pressure and prevents flow loss that would otherwise reduce pump output and discharge capacity.
  • Fluid System Safety — A failed or cross-threaded fitting can cause uncontrolled fluid discharge under pressure; replacing with the correct OEM fitting restores safe, sealed operation.

A nipple fitting serves as a threaded connector within the pump's piping and fluid-transfer circuit, linking sections of hose, pipe, or manifold to maintain a continuous, sealed flow path. In a high-volume trash pump like the PTS4V, the fitting must hold a reliable seal under sustained pressure and exposure to abrasive or debris-laden fluids. When a nipple fitting corrodes, cracks, or loses thread integrity, it allows pressure to escape, reducing discharge efficiency and creating the risk of uncontrolled fluid release at the connection point.
