Description
Overview:
This Non Genuine Exhaust Valve is a direct replacement for Honda GX120 engines, engineered to restore reliable exhaust sealing and gas flow. Made from heat‐resistant, hardened steel, it withstands high temperatures and repeated thermal cycles typical of small petrol engines. The valve works within the cylinder head to open and close the exhaust port, helping maintain smooth running, efficient combustion, and consistent power. It replaces OEM part number 14721-ZF0-000 and suits common Honda GX120 applications found in compactors, generators, water pumps, and other site or garden machinery. Designed for a precise fit in models such as GX120 and GX120K1, it is a practical choice when refreshing a tired cylinder head during routine maintenance or a top-end overhaul. Supplied as a single exhaust valve.
Key Features:
- Non Genuine replacement for Honda OEM 14721-ZF0-000
- Heat‐resistant hardened steel construction for durability under high exhaust temperatures
- Precision‐machined head and stem for correct seating and smooth operation
- Helps maintain compression sealing and efficient exhaust scavenging
- Consistent dimensions for reliable fitment in GX120 family engines
- Smooth stem finish to reduce guide wear and friction
- Supports stable idle, easier starting, and steady power delivery
- Suitable for routine service work or full cylinder head rebuilds
- Cost‐effective alternative to genuine parts without compromising core function
- Supplied as a single exhaust valve for one cylinder position
Typical Applications:
Used during engine repairs or services when the exhaust valve is worn, burnt, pitted, or leaking. Common on Honda GX120-powered equipment such as generators, water pumps, plate compactors, pressure washers, tillers, and light construction or horticultural machinery. Ideal when refurbishing heads, addressing loss of power, misfires, or poor starting linked to exhaust valve sealing.
