The Wacker Neuson Heat Shrink Tube is a genuine OEM component designed for the PS3 and PS4 series submersible pumps, including the PS3-5503, PS4-5503, PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF models across a wide range of voltage configurations. As a factory-sourced part, the meets the exact material and dimensional specifications set by Wacker Neuson for these pump families. This tube is built to provide dependable insulation and wire protection in the demanding wet environments these submersible pumps operate in. With broad fitment spanning 75mm/3in and 100mm/4in pump variants in 50Hz, 60Hz, and high-output configurations, this single part number covers an extensive range of PS series units.
Key Features
- Correct Insulation Grade for Submersible Service — Engineered to the dielectric and heat-resistance specifications required for electrical connections inside water-exposed pump housings.
- Genuine OEM Sourcing — Supplied directly from Wacker Neuson, ensuring material composition and shrink ratio match the original assembly specification for the PS3 and PS4 pump families.
- Drop-In Replacement — Sized to fit the existing wire harness connections in the PS3-5503, PS4-5503, PS4-7503, and PS4-11003 series without trimming or adapting adjacent components.
- Broad Voltage Compatibility — Covers pump configurations running at 220V, 440V, 575V (60Hz), and 400V (50Hz), making it the correct service part across the full PS series voltage lineup.
- Electrical Safety in Wet Environments — Properly applied heat shrink tubing is critical in submersible pump wiring; a failed or missing sleeve exposes conductors to water ingress, creating a shock hazard and risking motor failure.
Heat shrink tubing is used to insulate, seal, and protect electrical wire connections and splices inside submersible pump assemblies. When heat is applied, the tubing contracts tightly around the conductor or joint, creating a moisture-resistant barrier that prevents water infiltration and short circuits — both of which are serious risks in a fully submerged operating environment. If the tubing cracks, shrinks unevenly, or is missing entirely, exposed wiring can allow water contact with live conductors, leading to motor burnout, tripped breakers, or an electrical safety hazard on the jobsite.
