Description
Overview:
The Gasket Head for Robin Subaru EX21 engines is a precision-cut sealing component for the top end of a single-cylinder petrol engine. It sits between the cylinder head and the engine block to maintain compression and to prevent leakage of combustion gases and oil. Manufactured from heat-resistant gasket materials suitable for air-cooled industrial engines, it is built to cope with repeated heating and cooling cycles. This direct-fit replacement is purpose-made for the Robin Subaru EX21 engine commonly found on compact machinery and power equipment. It helps restore correct sealing after head removal or overhaul, supporting reliable cold starts, steady running, and full power output. Common reference numbers for this part include RB277 15001 13 and 277 15001 13.
Key Features:
- Engineered profile to match the EX21 cylinder head and fire ring area for a dependable seal
- Heat- and pressure-resistant construction for long service life in industrial use
- Helps maintain correct compression and prevents blow-by and oil mist leaks
- Stable sealing under thermal cycling and vibration typical of small plant machinery
- Clean, flat faces for good conformity when fitted to properly prepared surfaces
- Direct-fit replacement that works with standard head bolts and dowel locations
- Supports consistent performance after routine maintenance or top-end rebuilds
- Compatible with standard torque procedures and tightening sequences for EX21
- Suitable for use with unleaded petrol engines used in site and garden equipment
- Designed to minimise rework by reducing the risk of re-sealing or early leaks
