Piston Ring Compressor Set 11pc Service Tool Kit

A practical piston ring compressor set for engine service and rebuild work, covering ring fitting and groove cleaning in one kit. Used when installing pistons and servicing ring grooves, it gives you the key tools needed for common engine repair jobs without piecing items together separately.

Suitable for garage work, workshop use and general vehicle maintenance, this set is useful when rebuilding engines, replacing piston rings or cleaning carbon and residue from ring grooves before reassembly. It suits mechanics, engine builders and experienced DIY users who need to compress piston rings for fitting and clean grooves accurately during servicing.

The kit includes three piston ring compressors with ratchet key operation, covering 53 to 125mm and 90 to 175mm capacities, along with a piston ring tool rated for 50 to 100mm. A piston ring groove cleaning tool fits 2 to 5in. / 51 to 127mm, with three blade size ranges supplied for different groove dimensions. An offset driver with Phillips and slotted ends is also included, giving added access where space is awkward. The mix of sizes helps cover a useful spread of engine service work and keeps the main tools together for repeated workshop use.
