The Multiquip 22219 O-Ring Size 2-228N-90 2.25 Dia. X.139 is a genuine OEM sealing component designed for Whiteman and International ride-on power trowel models including HHNG5, HHXG5, HHXD5, HHXDF4-DF5, EHHNK5, HTNS5S-2, JTNSW24HTCSL, JTNSW20HTCSL, JTNSW20, JTNS20, and HHXD5-ES. Sourced directly from Multiquip, this O-ring matches the original specification exactly — ensuring the correct diameter, cross-section, and durometer for a proper hydraulic or fluid seal. When sealing integrity matters on a high-cycle piece of finishing equipment, using the genuine OEM part keeps fluid circuits performing as intended and protects surrounding components from contamination or pressure loss.
Key Features
- Genuine OEM Sealing Specification — Manufactured to the exact 2.25-inch outer diameter and .139-inch cross-section spec, matching the original compound and durometer hardness for consistent compression and fluid retention.
- Direct-Fit Replacement — Dimensioned to drop into the original groove without adjustment, maintaining the designed sealing surface and clamping load across the joint.
- Broad Trowel Compatibility — Fits a wide range of Whiteman and International ride-on power trowel models: HHNG5, HHXG5, HHXD5, HHXDF4-DF5, EHHNK5, HTNS5S-2, JTNSW24HTCSL, JTNSW20HTCSL, JTNSW20, JTNS20, and HHXD5-ES.
- Fluid System Integrity — A correctly seated O-ring prevents hydraulic fluid leaks and pressure drop that can degrade blade pitch control and drive response on ride-on trowel systems.
- Hydraulic System Safety — Compromised O-rings in hydraulic circuits can cause uncontrolled blade angle changes or drive loss; replacing with a properly rated OEM seal maintains predictable machine behavior.
An O-ring is a circular elastomeric seal that fits into a machined groove and is compressed between mating surfaces to block the passage of fluid or gas. In ride-on power trowels, O-rings appear throughout the hydraulic system — including pump connections, valve bodies, and cylinder ports — where they maintain the pressure needed to control blade pitch and machine propulsion. When an O-ring degrades, cracks, or takes a compression set, it loses its ability to seal, resulting in fluid weeping, pressure loss, and inconsistent or sluggish control response. Replacing a worn O-ring promptly with the correct OEM-specification part restores full hydraulic integrity and prevents secondary damage to valves and seals downstream.
