Wacker Neuson 5000205485 O-Ring

The Wacker Neuson is a genuine OEM O-Ring designed for a broad range of Wacker Neuson equipment, including DPU-series reversible vibratory plate compactors, PT3H centrifugal trash pumps, HSH350 hydronic surface heaters, and E1100 ground heaters. As a direct OEM replacement, this O-Ring is manufactured to the same material and dimensional tolerances as the original, ensuring a consistent, leak-free seal across every application it serves. Fitment covers an extensive range of DPU models — from the DPU 3050H and DPU 3060H through the DPU 3750Hts, DPU 3760Hts, DPU 5260H, DPU 5275H, DPU 6260H, DPU 6275H series, and their variants — as well as PT3H pumps and HSH350 surface heaters. Confirming your machine's model number before ordering ensures this is the correct O-Ring for your application.

Key Features

• OEM-Grade Seal Material — Manufactured to Wacker Neuson's original compound and durometer specification, maintaining consistent compression and elasticity under fluid and pressure cycling.
• Drop-In Sealing Replacement — Dimensioned to seat correctly in the original groove without trimming or shimming, covering hydraulic, fuel, and water circuit applications across multiple machine families.
• Wide Multi-Family Fitment — Confirmed for DPU 3050H through DPU 6275H reversible plate compactors, PT3H trash pumps, HSH350 hydronic surface heaters, and E1100 ground heaters.
• Leak Prevention at Critical Joints — A correctly seated O-Ring maintains system pressure and prevents fluid loss; a deteriorated or incorrectly sized O-Ring leads to seepage, contamination, and accelerated component wear.
• Fuel and Fluid System Integrity — Where this O-Ring seals fuel or hydraulic circuits, maintaining its condition is essential to safe, stable machine operation and preventing uncontrolled fluid exposure.

An O-Ring is a precision-molded elastomeric seal that sits in a machined groove between two mating surfaces — such as a port, fitting, cover, or pump housing — and compresses to form a fluid-tight barrier. Across the DPU compactor, PT3H pump, and HSH heater platforms, O-Rings like the 5000205485 seal hydraulic, water, and fuel passages, preventing leaks that would otherwise compromise system pressure and machine output. When an O-Ring ages, hardens, or is damaged during service, the resulting leak can cause fluid contamination, pressure loss, or component failure, making timely replacement a critical part of any seal or service kit job.
