Description
Overview:
This genuine Loncin valve stem seal (MPN: 140400011-0001) controls oil at the valve guide to stop it entering the combustion chamber, helping your engine run cleanly and efficiently. Built with an oil- and heat-resistant elastomer bonded to a steel outer shell, it provides a stable, long-lasting seal under high temperatures and sustained vibration. Designed for Loncin small petrol engines, it is a direct-fit part for the G120F A Shaft and R Shaft variants and widely used across related models such as the G160F. It is suitable for engines powering equipment like generators, water pumps and compact garden or site machinery. Using the correct OEM seal helps reduce oil consumption, minimise smoke, and protect valves and guides over the long term.
Key Features:
- Genuine Loncin part for assured fit and performance
- Prevents oil leakage at the valve stem to support clean combustion
- Durable oil- and heat-resistant elastomer with a robust steel shell
- Engineered to withstand vibration and continuous running
- Helps reduce oil consumption, exhaust smoke and plug fouling
- Supports reliable starting and stable idle by limiting oil ingress
- Direct replacement with OEM dimensions for Loncin engines
- Suitable for routine servicing and preventive maintenance
- Compact press-fit design for straightforward installation with standard tools
- MPN: 140400011-0001
Typical Applications:
Used during top-end rebuilds or valve service on Loncin single-cylinder engines fitted to portable generators, water pumps and light construction or garden equipment. Ideal when resolving oil burning, blue smoke at start-up, or oil fouling on machines powered by G120F, G160F, G200F and related Loncin engines.
Also known as:
Valve guide seal, stem oil seal, valve oil seal, valve guide oil seal, top-hat seal. These terms all refer to the small seal that controls oil flow where the valve stem passes through the guide.
