The Wacker Neuson Gasket 110MM Quick Disconnect Coupler is a genuine OEM component designed for the PS4 and PSC4 series submersible pumps. This includes PS4-3703, PS4-5503, PS4-7503HH, PS4-7503HF, PS4-11003HH, PS4-11003HF, PSC42203, PSC43703, PSC42303EX, and PSC43803EX variants. As a factory-sourced part, the is manufactured to the same specification as the original, ensuring a consistent seal at the quick disconnect coupler interface. Verify your model number before ordering to confirm compatibility with your specific pump configuration.
Key Features
- OEM Sealing Specification — Manufactured to Wacker Neuson's original compression and material grade requirements for 110MM quick disconnect coupler applications, ensuring the seal performs as intended under pump operating pressures.
- Direct-Fit Replacement — Sized specifically for the 110MM quick disconnect coupler interface; seats into the coupling without alteration, maintaining the integrity of the discharge connection.
- Broad PS4 and PSC4 Coverage — Compatible across the PS4-3703, PS4-5503, PS4-7503, and PS4-11003 model variants, as well as PSC4-series submersible pumps including explosion-protected EX models.
- Discharge Integrity — A worn or compressed-out coupler gasket allows water to bypass the discharge connection, reducing pump output and creating wet, unsafe conditions at the coupling. Replacing this gasket restores a full, leak-free seal.
- Fluid Containment Compliance — On submersible pumps used in contaminated water or confined space applications, a sound coupler seal is essential to keep discharge flow directed safely through the hose and away from the work area.
The quick disconnect coupler gasket forms the sealing surface between the pump's discharge outlet and the connected hose or pipe fitting. It compresses against the coupler faces when the connection is locked, preventing water from escaping at the joint under operating pressure. Over time, continuous wet exposure, temperature cycling, and mechanical reconnections cause the gasket material to degrade, flatten, or crack, resulting in leaks at the discharge point that reduce pumping efficiency and can create slip hazards on the worksite. Replacing the 5000059980 restores a tight, pressure-holding seal and returns the pump's discharge connection to full working condition.
