The Bomag 05722794 Square Ring is a genuine OEM sealing component designed for the BMP 851 trench compactor. Sourced directly from Bomag, this square ring meets the original engineering specifications for the BMP 851, ensuring a proper seal where it counts. When a square ring fails or degrades, fluid leaks and pressure loss can compromise the hydraulic or mechanical system it protects — making prompt, accurate replacement essential. Order part number 05722794 with confidence knowing it is the correct OEM component for your machine.
Key Features
- OEM Sealing Integrity — manufactured to Bomag's original material and dimensional specifications, delivering the compression and fluid resistance required for this sealing application
- Direct Drop-In Replacement — this square ring seats into the same groove as the original, requiring no reworking of mating surfaces or hardware
- Confirmed BMP 851 Fitment — verified for the BMP 851 trench compactor, so you can order part number 05722794 with full confidence in compatibility
- Sustained System Pressure — a correctly seated square ring maintains hydraulic or mechanical circuit pressure, keeping the compactor operating at full efficiency across demanding compaction cycles
- Leak Prevention — degraded or incorrectly sized seals allow fluid bypass that can escalate into larger system damage; this genuine OEM part restores the barrier to its original integrity
A square ring is a sealing element used to prevent fluid — typically hydraulic oil or lubricant — from escaping past a joint, bore, or fitting within the machine's system. Unlike a round O-ring, its flat-sided profile provides a larger sealing surface area and more stable seating in rectangular grooves, reducing the risk of the seal rolling or shifting under pressure. When a square ring wears, hardens, or is cut during reassembly, the resulting leak can cause pressure drops, contamination, and accelerated wear to surrounding components.
