These Hippotech fuel shutoff valves are exact replacements for Honda GCV160, GCV190, and several other Honda small engines - and you get five in a pack, which is fantastic if you maintain multiple mowers or want to have spares on hand. The part number 16950-Z0Y-003 is identical to the OEM Honda valve, so installation is straightforward with no modifications needed. The valve controls fuel flow from the tank to the carburetor, which is crucial for preventing flooding and making storage easier. Turning the fuel off when you're done mowing helps prevent carburetor issues caused by old gas sitting in the float bowl. The build quality is solid with clean threads that screw in smoothly without cross-threading. The knob is easy to grip even with gloves on, and the on/off positions are clearly marked. These work with Honda GC135, GCV135, GCV160 series, GCV190 series, and fit numerous Honda mower models including HR215, HRB215, HRC215, HRR216, HRS216, HRX217 and more. Having multiple valves means you can service several mowers at once or keep extras for when friends or neighbors need replacements. The material feels durable and should hold up well to fuel exposure and outdoor conditions. If you're tired of fuel leaking from worn-out shutoff valves or dealing with hard-to-turn old valves, these Hippotech replacements are affordable insurance against fuel system problems. Installation is simple - just drain the fuel, swap the old valve for the new one, and you're back in business. Seriously, for the price of having a mechanic replace one valve, you can buy this five-pack and handle multiple mowers yourself!
