Key Features
- OEM-Grade Sealing Material — manufactured to Husqvarna's exact compound and durometer specification, ensuring the correct compression set and resistance to fluid or grease exposure in power trowel applications.
- Exact-Fit Replacement — dimensioned to match the original groove geometry on the CRT36, CRT48, and CRT48PS, so the O-Ring seats correctly without modification.
- Broad CRT Series Coverage — a single part number covers the CRT36, CRT48, and CRT48PS power trowels, simplifying parts ordering across your fleet.
- Leak Prevention — a properly seated O-Ring maintains fluid or lubricant containment, protecting surrounding components from contamination and wear that a degraded seal would allow.
- Verified Husqvarna Part Number — cross-reference 598992401 against your CRT series parts diagram to confirm placement before installation.
An O-Ring creates a static or dynamic seal between mating surfaces, preventing fluid, lubricant, or air from escaping a joint or housing. In a power trowel, O-Rings are used throughout hydraulic connections, gearbox covers, and other sealed assemblies to maintain system pressure and keep contaminants out. When an O-Ring hardens, cracks, or is displaced, it allows leakage that can lead to fluid loss, reduced hydraulic performance, or accelerated wear on adjacent components — making timely replacement essential to keeping the machine operating correctly.
