The Multiquip 9038 O-Ring A-257 Viton is a genuine OEM sealing ring designed for a wide range of Multiquip and Whiteman power trowels, walk-behind rollers, and ride-on rollers. This Viton-compound O-Ring provides a chemical- and heat-resistant seal for fluid systems across compatible equipment including the JWN24HTCSL, HTN28K, HTN27K, HDA Series, V305EH, MRH800GS, AR14H, and R2000H. As a genuine OEM part, Multiquip 9038 is manufactured to the exact material and dimensional specifications required for proper function in these machines. Sourced directly through authorized distribution at DHS Equipment, this is the correct replacement seal when the original O-Ring shows wear, cracking, or leakage.
Key Features
- Viton Material Grade — Fluoroelastomer (Viton) compound delivers superior resistance to heat, hydraulic fluids, and chemical exposure compared to standard rubber O-Rings, maintaining a reliable seal under demanding operating conditions.
- A-257 Dimensional Spec — Produced to the A-257 dash size standard, this ring drops into the correct groove geometry for a leak-free, compression-fit seal with no recutting or shimming needed.
- Broad Multiquip Fitment — Confirmed for JWN24HTCSL, HTN28K, HTN27K, HDA Series walk-behind trowels, V305EH, MRH800GS, AR14H, and R2000H rollers — one part number serving multiple machine families.
- Leak Prevention — A failed or hardened O-Ring allows fluid bypass, leading to pressure loss, contamination, or external leakage. Replacing with the correct Viton seal restores proper system integrity and prevents progressive damage.
- Genuine OEM Replacement — Supplied as a genuine Multiquip OEM component, matching the original specification for material durometer, inner diameter, and cross-section — critical for sealing performance in hydraulic and fluid circuits.
An O-Ring is a precision elastomeric seal that sits in a machined groove between two mating surfaces or around a shaft and port, preventing fluid or air from escaping the system. In power trowels and rollers, O-Rings are commonly used in hydraulic circuits, engine fluid passages, and pump assemblies where maintaining pressure and preventing contamination are essential to correct machine operation. When an O-Ring hardens, cracks, or takes a permanent set from heat cycles, it loses its ability to conform to the mating surface, causing leaks that can lead to fluid loss, pressure drop, or contamination of surrounding components.
