The Honda 19505-KS6-700 Water Hose Clamp A is a genuine OEM component designed for GX620, GX630, GX670, and GX690 horizontal shaft engines. As a direct OEM replacement, this clamp is manufactured to Honda's exact specifications, ensuring a secure, leak-free connection in the engine's cooling or liquid-routing circuit. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and fitment can vary across production runs.
Key Features
- Genuine Honda OEM Part — sourced directly from Honda, this clamp meets the same dimensional and retention standards as the original, keeping hose connections secure under operating pressures and temperatures the engine encounters.
- Correct Clamp Geometry — the "A" designation identifies this as a specific variant; verify part number 19505-KS6-700 against your engine's parts diagram to confirm you have the right clamp for your application.
- Broad Large-Displacement Fitment — compatible with GX620, GX630, GX670, and GX690 horizontal shaft engines, covering Honda's top-tier commercial engine lineup.
- Serial Number Verification Recommended — Honda updates components across production runs, so always cross-reference your engine's serial number with the fitment table to confirm this is the correct clamp for your unit.
A water hose clamp secures a coolant or water hose to its fitting, preventing the hose from slipping off or leaking under the pressure and vibration of normal engine operation. On large-displacement horizontal shaft engines like the GX620 through GX690 series, a failed or loose clamp can allow coolant loss, leading to overheating and potential engine damage. Replacing a worn or damaged clamp with the correct OEM part restores a proper seal and protects the engine's liquid-routing system from unplanned leaks.
