The Wacker Neuson O-Ring is a genuine OEM component designed for the LTN4Y and LTN5Y series light towers, including LTN4Y, LTN4Y RH, LTN4Y SA, LTN4Y 60 Hz, LTN4Y 120V/60Hz, LTN5Y, LTN5Y CH, LTN5Y SA, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypa, and LTN5Ypk models. Sourced directly from Wacker Neuson, this is the same O-Ring built into these machines at the factory — not an approximation. Choosing a genuine OEM part means you get the correct material compound, dimensional tolerances, and compression characteristics needed to maintain a proper seal in your machine.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's exact compound and durometer specifications, ensuring the O-Ring seats and compresses correctly for a lasting seal.
- Drop-In Replacement — Dimensionally identical to the original, so it seats into the same groove or port without adjustment or reworking of surrounding components.
- Broad LTN Series Compatibility — Fits across the full LTN4Y and LTN5Y light tower families, including SA, RH, CH, UK, 60 Hz, 120V/60Hz, HD, and pk variants.
- Leak Prevention Where It Counts — A correctly fitted O-Ring maintains fluid or air containment within the assembly; a worn or hardened O-Ring leads to leaks, pressure loss, and potential system damage.
- Genuine Wacker Neuson Part — Part number 5100075845 is the verified OEM reference, so you can order with confidence that the part matches what's already in your machine.
An O-Ring is a small loop of elastomeric material used to create a reliable seal between two mating surfaces, preventing the passage of fluid or air past a joint or port. In light tower applications, O-Rings are commonly found in fuel system connections, hydraulic fittings, and fluid reservoirs where maintaining a tight seal is critical to safe and consistent operation. When an O-Ring degrades — through heat cycling, chemical exposure, or compression set — it loses its ability to seal effectively, which can result in fluid leaks, contamination ingress, or loss of system pressure that affects overall machine performance.
