Description
Overview:
This Piston Ring Set is a genuine Robin/Subaru replacement for EX13 engines (OEM No. RB276 23511 17). The rings are manufactured from wear‐resistant metal alloys and precision finished to maintain a tight seal between the piston and cylinder wall. By restoring correct sealing, the set helps recover compression, reduce blow‐by, and control oil consumption, supporting reliable starting and steady running. It is suitable for single‐cylinder, air‐cooled EX13 engines commonly fitted to construction and garden machinery. Supplied as a complete set for one piston, with compression and oil control rings configured for the EX13 profile. Ideal for routine overhauls or repairs where power has dropped or oil usage has increased. Genuine Robin/Subaru part for consistent fit and performance.
