Universal Piston Ring Compressor Set, 6-Band Size, Piston Installer Tool

Universal Piston Ring Compressor Set, 6-Band Size — the essential piston installer tool for clean, hassle-free engine assembly. This six-band set is designed to compress piston rings precisely as you install pistons into cylinders, helping prevent ring damage and ensuring a proper seal from the first start.

Built for versatility, the compressor fits a wide range of piston diameters to cover most common car engines. The tool tightens from 2-7/8 inches (73 mm) up to 4-3/8 inches (111 mm) in diameter, with six adjustable bands that let you dial in the perfect fit. Before purchasing, please verify your piston size to ensure the best match.

The Piston Ring Compressor Pliers feature a ratcheting lock that holds the handles in position, making one-handed installation easier and reducing the risk of dropping or misaligning the piston. The design minimizes ring distortion during compression, protecting the rings and the cylinder walls while you push the piston into place.

Durability is built in: crafted from high-strength metal, this set is wear resistant, bend-proof, and hard enough to withstand demanding shop use. A heavy-duty storage box keeps all bands, accessories, and the tool organized and ready for transport, so nothing gets lost between jobs.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
