Multiquip 2309 O-Ring 2-13/16" Viton

The Multiquip 2309 is a genuine OEM 2-13/16" Viton O-Ring designed for Whiteman and Multiquip ride-on and walk-behind power trowel models including the HHXDF4, HHXDF5, HHXD5, HHXG5, HDA Series, HTN27K, HTN28K, HTNS5S-2, and JWN24HTCSL/HSCSL series. As a direct OEM replacement, part 2309 delivers the exact material specification and dimensional fit required to maintain a proper seal in your machine. Sourced directly through Multiquip's authorized parts network, this is the same component used in original assembly. Keep a spare on hand to avoid unexpected seal failures during critical finishing operations.

Key Features

• Viton Material Grade — Fluoroelastomer construction provides superior resistance to hydraulic fluids, fuel, and high operating temperatures compared to standard rubber O-rings.
• Exact 2-13/16" Sizing — Dimensionally matched to the original groove seat, allowing this O-ring to seat correctly without gaps or over-compression that could cause premature seal failure.
• Genuine OEM Part — Multiquip part number 2309 is manufactured to the same specification as the component installed at the factory, ensuring consistent sealing performance.
• Broad Trowel Family Coverage — Fits HHXDF4, HHXDF5, HHXD5, HHXG5, HDA Series, HTN27K, HTN28K, HTNS5S-2, and JWN24HTCSL/HSCSL power trowels, covering both ride-on and walk-behind configurations.
• Maintains Fluid Integrity — A correctly seated O-ring prevents fluid leaks that can lead to hydraulic pressure loss, contamination, or accelerated wear on surrounding components.
• Fluid System Compliance — Using the correct Viton specification is especially important in fuel and hydraulic circuits where improper seal materials can degrade rapidly and introduce contaminants into the system.

An O-ring is a precision sealing element used at joints, ports, and connections throughout a machine's fluid circuits. Its role is to create a pressure-tight seal between mating surfaces, preventing leaks of hydraulic fluid, fuel, or lubricants. When an O-ring hardens, cracks, or deforms from heat and chemical exposure, it loses its ability to seal — leading to fluid loss, pressure drop, and potential damage to pumps, valves, and actuators. Replacing a worn O-ring with the correct Viton-grade part like Multiquip 2309 restores the integrity of the sealed circuit and keeps the trowel operating as intended.
