Description
Overview:
This Cylinder Head O-Ring is a non-genuine replacement for Yanmar small diesel engines and directly replaces OEM part number 114250-01380. Moulded from a durable, oil- and heat‐resistant elastomer, it provides a tight seal at the cylinder head joint to help prevent loss of compression and leakage of combustion by‐products or lubricating oil. Built to consistent dimensions for a precise, secure fit, it is designed to cope with high pressure and thermal cycling typical of working engines. Suitable for maintenance and repair on compact single‐cylinder diesels found in construction and garden equipment, including the Yanmar L40 and L48. A practical choice for preventative servicing or rebuilds where reliable sealing is essential. Internal reference/MPN: 320 190. Non Genuine Part.
