Cal-Van - Allstart Piston Ring Compressor Band to

The Cal-Van Allstart piston ring compressor band (also called a piston ring compressor or piston installer band) helps you install pistons into engine cylinder bores. It squeezes the piston rings flush with the piston so the assembly can slide into the block without damaging the rings or the cylinder wall.

Key Features:

• Wraps around the piston and covers the rings, compressing them evenly for installation
• Hooks into ratcheting pliers, so the band can be tightened in small increments for accurate compression
• Works with the block positioned vertically or horizontally
• Designed for engine builders, rebuilders and professional repair shops
• Made by Cal-Van Tools, which has made automotive service tools since 1939

To use it, place the band around the piston so it covers the rings and squeeze it tight. Set the piston into the cylinder, then tap it lightly with a hammer handle to seat it in the bore. Choose the child item that matches your piston bore diameter.
