Multiquip 22220 O-Ring Size 2-225N-90 1.875 Dia. X .139

The Multiquip 22220 is a genuine OEM O-Ring Size 2-225N-90 1.875 Dia. X.139 designed for Whiteman and international ride-on power trowel models including the HHXG5, HHXD5, HHNG5, HHXDF4-DF5, EHHNK5, HTNS5S-2, JTNSW24HTCSL, JTNSW20HTCSL, JTNSW20, JTNS20, and HHXD5-ES. As a genuine OEM component, part 22220 is manufactured to the exact dimensional tolerances required to maintain proper sealing performance in these machines. Sourced directly through Multiquip's authorized parts network, this O-ring is a direct-fit replacement that installs without modification to keep your trowel running as intended.

Key Features

• Exact Dimensional Spec: — Manufactured to a precise 1.875 inch outer diameter and .139 inch cross-section, matching the original seal geometry for consistent compression and leak-free sealing.
• Genuine OEM Quality: — Produced to Multiquip's material specifications for the correct durometer and elastomer grade required in ride-on trowel hydraulic or fluid circuits.
• Broad Trowel Fitment: — Compatible with a wide range of Whiteman and international ride-on power trowel models, including HHXG5, HHXD5, HHNG5, HHXDF4-DF5, EHHNK5, HTNS5S-2, JTNSW24HTCSL, JTNSW20HTCSL, JTNSW20, JTNS20, and HHXD5-ES.
• Drop-In Replacement: — Sized to seat directly into the original groove without trimming, stretching, or adapting — swap it in and restore a proper seal immediately.
• Protects System Integrity: — A correctly seated O-ring prevents fluid bypass and pressure loss; a degraded or incorrectly sized seal can cause leaks, contamination, and accelerated wear on surrounding components.

An O-ring is a circular elastomeric seal that fits into a machined groove and creates a pressure-tight barrier between mating components. In ride-on power trowels, O-rings are used throughout hydraulic circuits, fluid ports, and mechanical assemblies to prevent leaks and maintain operating pressure. When an O-ring hardens, cracks, or takes a permanent set, it loses its ability to compress and seal — leading to fluid loss, pressure drop, and potential damage to pumps, valves, and other downstream components. Replacing a worn O-ring with the correct OEM part like the Multiquip 22220 restores the original sealing surface and keeps the machine operating at full capacity.
