Honda 91308-MB0-003 O-Ring (5.7X2.2)

The Honda 91308-MB0-003 O-Ring (5.7X2.2) is a genuine OEM replacement designed for H6522 compact tractors. As a factory-sourced component, this O-ring is manufactured to the exact dimensional specification Honda requires, ensuring a proper seal where it is needed. Honda supersedes parts at serial breaks, so confirm your unit's serial number against the fitment table before ordering to ensure part number 91308-MB0-003 is the correct application for your machine.

Key Features

• Exact OEM Specification — sourced directly from Honda, this O-ring matches the precise 5.7x2.2 mm dimensions called out in the H6522 parts catalogue, so it seats and seals as intended
• Drop-In Replacement — this part installs directly in place of the original, requiring no modification to surrounding components
• Compact Tractor Fitment — listed for the Honda H6522 compact tractor; verify your serial number against the fitment table to confirm this is the correct O-ring for your specific unit
• Seal Integrity — a correctly sized O-ring maintains a leak-free joint; a worn, cracked, or incorrectly dimensioned O-ring allows fluid to bypass the sealing surface, leading to leaks and potential component damage

An O-ring is a circular elastomeric seal used throughout a compact tractor's systems — hydraulic circuits, fluid passages, and threaded fittings — to prevent fluid from escaping at joints and connections. The ring is compressed between two mating surfaces, forming a pressure-tight barrier. When an O-ring hardens, cracks, or takes a permanent set from heat and age, that barrier breaks down and fluid begins to seep past the seal, which can lead to system pressure loss or fluid contamination if left unaddressed.
