Wacker Neuson 5000059982 Gasket 50MM Q.D. Coupler

The Wacker Neuson Gasket 50MM Q.D. Coupler is a genuine OEM component designed for the PS2, PSA2, PST2, and PSC2 series submersible pumps. As a direct Wacker Neuson OEM part, the is manufactured to the exact material and dimensional standards required for a proper seal at the quick-disconnect coupler interface. Fitment spans a wide range of PS2-series models including the PS2-500, PS2-750, PS2-800, PS2-1503, PS2-2203, PS2-3703, PST2-400, PSA2-500, PSA2-800, PSA2-1503L, PSA2-2203L, and related variants. Sourcing the correct OEM gasket ensures the coupler connection remains leak-free and maintains rated pump performance in demanding dewatering applications.

Key Features

• OEM Material Compliance: — Manufactured to Wacker Neuson's exact compound and dimensional spec for the 50MM quick-disconnect coupler, ensuring correct compression and sealing behavior at that joint.
• Drop-In Coupler Replacement: — Sized to seat directly in the Q.D. coupler without trimming or shimming, keeping the connection process straightforward during pump maintenance or hose changeouts.
• Broad PS2-Series Coverage: — Confirmed fitment across PS2, PSA2, PST2, and PSC2 submersible pump families in both 110 V and 230 V/400 V configurations, covering a wide range of Wacker Neuson dewatering equipment.
• Leak Prevention at the Discharge Connection: — A worn or damaged coupler gasket allows water to bypass the seal under pump pressure, reducing flow efficiency and potentially damaging surrounding components. This replacement restores a positive, pressure-rated seal.
• Genuine OEM Part Number Verified: — Sold under Wacker Neuson part number 5000059982, matching the original service documentation for all listed PS2-series variants.

The Q.D. Coupler Gasket seals the quick-disconnect coupling point on the pump's discharge outlet, preventing water from escaping around the connection rather than through the hose or pipe. In submersible pump applications, this joint is under constant pressure whenever the pump is running, so even minor gasket degradation can lead to visible leaks, reduced discharge pressure, and accelerated wear on the coupler itself. Replacing the gasket at the first sign of seeping or during scheduled maintenance keeps the discharge circuit sealed and the pump delivering its full rated output.
