The Wacker Neuson O-Ring is a genuine OEM component 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 is an authentic OEM part manufactured to the same standards as the original installed at the factory. Having the correct O-Ring on hand keeps fluid systems sealed and operating as intended, avoiding the leaks and downtime that come with a worn or damaged seal. Verify your model number against the fitment list before ordering to ensure a correct match.
Key Features
- Genuine OEM Sealing Material — Manufactured by Wacker Neuson to exact compound and dimensional specifications, ensuring correct compression and sealing performance in the original application.
- Drop-In Replacement — Sized and profiled to seat directly into the original groove without modification, maintaining a consistent, leak-free seal from the moment it is installed.
- Broad LTN Series Compatibility — Fits a wide range of LTN4Y and LTN5Y series Wacker Neuson light towers, covering standard, SA, CH, UK, RH, 60 Hz, 120V/60Hz, HD, and pk variants.
- Prevents Fluid Loss and System Contamination — A failed or deteriorated O-Ring allows fluid to bypass the seal, leading to leaks, pressure loss, and potential ingress of contaminants that can damage surrounding components.
- Authentic Part Number Traceability — Part number 5100075870 is the genuine Wacker Neuson reference, giving you confidence that you are ordering the correct part for your specific machine.
An O-Ring is a small circular seal that fits into a machined groove to create a pressure-tight barrier between two mating surfaces or components. In light tower applications, O-Rings are commonly used within fuel, hydraulic, and coolant circuits to prevent fluid from escaping past fittings, valves, or housing joints. When an O-Ring becomes hardened, cracked, or compressed beyond its usable range, it loses its ability to form a proper seal — resulting in visible leaks, pressure drops, and the risk of fluid contamination that can escalate into more serious mechanical damage if left unaddressed.
