Key Features

• Genuine OEM Material Integrity — Manufactured to exact OEM tolerances, ensuring the sealing surface and compression characteristics match the original seal washer specification for this application.
• Drop-In Replacement — Designed to install in the same position and orientation as the original, connecting directly without additional hardware or modification.
• Confirmed Fitment — Verified for use on the STXD6i and HTXD6i Whiteman hydrostatic ride-on power trowels.
• Fluid Containment Performance — A correctly functioning seal washer prevents fluid leaks at critical connection points, maintaining proper hydraulic or engine system pressure and preventing contamination.
• Fuel and Fluid System Safety — A worn or compromised seal washer can lead to fluid seepage around engine or hydraulic components, making timely replacement important for safe operation.

A seal washer creates a leak-proof barrier at threaded or bolted fluid connections within the engine or hydraulic system. It works by deforming slightly under torque to fill any microscopic gaps between mating surfaces, preventing oil, fuel, or hydraulic fluid from escaping. When a seal washer becomes worn, cracked, or compressed beyond its service life, it loses its ability to maintain that barrier — leading to fluid leaks that can cause pressure loss, component damage, or unsafe operating conditions if left unaddressed.
