The Wacker Neuson Seal, O-Ring is a genuine OEM component designed for the PTS4V series pumps. Sourced directly from Wacker Neuson, this O-ring is manufactured to the exact material and dimensional specifications used in original production — ensuring a correct, leak-free fit from the moment it is installed. If you are servicing a PTS4V pump, verifying the part number against your machine's serial configuration is always recommended before ordering.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's original compound and durometer specifications, delivering the correct compression and chemical resistance required for pump sealing applications.
- Drop-In Installation — Dimensionally identical to the original, this O-ring seats into its groove without reworking or adapting surrounding components.
- PTS4V Series Fitment — Confirmed compatible with PTS4V series pumps across multiple build configurations, including models 5100058545, 5100058546, and 5100060386.
- Leak Prevention — A correctly fitted O-ring maintains internal pressure boundaries and prevents fluid bypass — a worn or extruded seal can lead to fluid loss, contamination ingress, and accelerated wear on adjoining components.
- Genuine Wacker Neuson Part — Supplied as an authorized OEM replacement, so you can be confident the part matches the engineering intent of the original assembly.
An O-ring is a loop-shaped seal used to prevent fluid or gas from passing between two mating surfaces. In pump applications like the PTS4V, O-rings are used at critical junctions throughout the fluid path and housing assembly to maintain pressure integrity and keep contaminants out. When an O-ring ages, hardens, or becomes compressed beyond its usable range, it loses its ability to seal — leading to leaks, pressure loss, and potential damage to surrounding components. Replacing a worn O-ring promptly with the correct OEM part restores the sealing interface and keeps the pump operating as intended.
