The Wacker Neuson O-Ring is a genuine OEM O-Ring designed for the LTN4Y and LTN5Y series light towers, including the LTN4Y, LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Y SA, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypa, and LTN5Ypk models. Sourced directly from Wacker Neuson, this part is manufactured to the same specification as the original component that came with your machine. Keeping the correct O-Ring in service is essential to maintaining fluid integrity and preventing leaks that can lead to costly repairs or unexpected downtime. Confirm your model number against the fitment list before ordering to ensure an exact match.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compound and dimensional specification, ensuring correct compression and long-term sealing performance in this application.
- Direct Drop-In Replacement — Matches the original O-Ring profile exactly, seating into its groove without re-machining or fitting adjustments.
- Broad LTN Series Coverage — Compatible with a wide range of LTN4Y and LTN5Y light tower variants, including SA, RH, CH, UK, 60 Hz, 120V/60Hz, HD, and pk configurations.
- Leak Prevention Where It Counts — A failed or worn O-Ring allows fluid to bypass the seal, leading to contamination or pressure loss; replacing it promptly restores proper system integrity.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component, carrying the same part number used by Wacker Neuson dealers and service centers worldwide.
An O-Ring is a circular elastomeric seal designed to sit in a machined groove and compress between two mating surfaces, creating a fluid- or air-tight barrier. In light tower applications, O-Rings are used throughout fuel, hydraulic, and coolant circuits to prevent leaks at connections, fittings, and component interfaces. When an O-Ring hardens, cracks, or becomes deformed through heat cycling and age, it loses its ability to seal, which can result in fluid leaks, contamination ingestion, or pressure loss that affects machine operation. Replacing a worn O-Ring with the correct OEM part restores the seal to its original performance standard and protects the surrounding components from damage.
