The Bomag 05801182 Square Ring is a genuine OEM Square Ring designed for the BW 12 R pneumatic tyred roller. Sourced directly from Bomag, this component meets the original engineering specification for a correct, leak-free installation. This Square Ring is confirmed to fit the BW 12 R, making it a straightforward service part for technicians maintaining this machine. When it comes time to replace a worn or damaged seal, using the correct OEM part ensures the joint seals as intended.
Key Features
- OEM Material Grade — manufactured to Bomag's original compound and dimensional specification, ensuring the correct compression and seal behavior for this application
- Direct Drop-In Fit — engineered to match the exact groove dimensions of the BW 12 R, seating properly without rework or modification to mating surfaces
- Confirmed Fitment — verified for the BW 12 R pneumatic tyred roller, eliminating guesswork when ordering service parts
- Leak Prevention — a correctly seated square ring maintains fluid or air pressure at the joint; a worn or extruded ring leads to seeping, pressure loss, and accelerated wear on surrounding components
- Fuel and Fluid System Safety — proper sealing at critical joints prevents uncontrolled fluid loss, keeping the machine operating safely within designed pressure ranges
A square ring is a four-sided sealing ring used in place of a traditional O-ring in certain grooved joints and hydraulic or pneumatic connections. Its flat profile provides a larger sealing surface area and resists rolling or twisting in the groove during assembly, which makes it well suited to static and low-motion applications. When a square ring deteriorates — through heat cycling, compression set, or chemical exposure — the joint loses its seal, resulting in fluid seepage, pressure drop, or contamination ingress that can cause broader mechanical damage if left unaddressed.
