The Wacker Neuson Heat Shrink Tube is a genuine OEM electrical insulation component designed for the PS3 and PS4 series submersible pumps. This includes the PS3-5503, PS4-5503, PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF models across a wide range of voltage configurations — from 220V and 440V 60Hz units to 400V 50Hz and 575V 60Hz variants. Sourced directly from Wacker Neuson, part is manufactured to the exact specification required for safe, compliant electrical assembly within these pumps. Confirm your model number before ordering to ensure correct fitment across this broad PS-series range.
Key Features
- OEM Electrical Insulation Grade — Manufactured to Wacker Neuson's exact material and shrink-ratio specification, ensuring correct dielectric protection for submersible pump wiring connections.
- Direct-Fit Replacement — Sized to slip over existing conductors and terminals as originally assembled, requiring no cutting, splicing, or adaptation during installation.
- Broad PS-Series Compatibility — Fits PS3-5503, PS4-5503, PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF submersible pumps across multiple voltage and frequency ratings.
- Protects Critical Wiring Joints — A properly installed heat shrink tube seals and insulates electrical connections against moisture intrusion — essential in the permanently wet environment a submersible pump operates in.
- Electrical Safety Compliance — Using the correct OEM-specified heat shrink material maintains the insulation integrity of the pump's internal wiring, reducing the risk of short circuits, ground faults, or motor damage in submerged conditions.
A heat shrink tube is a polymer sleeve that contracts tightly around a wire, terminal, or splice point when heat is applied, forming a protective insulating layer. Inside a submersible pump, electrical connections are constantly exposed to water, and correctly rated heat shrink tubing is the primary barrier preventing moisture from reaching bare conductors or solder joints. When heat shrink tubing cracks, pulls back, or is improperly installed, water can wick into the connection and cause insulation breakdown, motor shorts, or electrical faults — failures that can take the entire pump out of service.
