Ratchet Piston Ring Compressor Options

Hold suitable piston rings compressed during installation with a ratchet-band tool offered in three height selections.

✅ Keep the rings gathered for insertion - The compressor band provides the temporary restraint used in a matching piston-installation procedure.

✅ Adjust the band around the assembly - A ratchet arrangement lets you take up the band as instructed.

✅ Choose the tool height for access - Three-, four- and six-inch labels provide different versions for the intended work.

Match the compressor to the piston and cylinder

Piston installation requires the rings, piston and bore to be prepared according to the engine's service procedure. The compressor handles the temporary ring-restraint step while the assembly is positioned for insertion.

Confirm the supported diameter and selected band height before purchase. Keep the tool square and follow the engine instructions rather than forcing the piston if an edge or ring does not move as expected.
