Piston Ring Expander Pliers

Handle suitable piston rings during installation with expanding pliers that give the ring a dedicated holding point.

✅ Open the ring with a matching tool - The pliers provide the spreading action used to position a compatible ring over the piston.

✅ Keep a grip on the installation step - Silicone-covered handles provide the hand-contact area during controlled operation.

✅ Reach with a compact hand tool - A 170 mm overall length fits the tool into an engine-assembly work area.

Fit the ring using controlled expansion

Piston rings need careful handling during assembly. Using an appropriate expander lets you work with the ring as a component rather than pulling it apart with fingers or improvised leverage.

Match the tool to the ring and follow the engine's installation instructions. Expand only as required and check the ring's position afterwards; these pliers are not a band compressor for inserting the assembled piston into the cylinder.
