SATA ST97501SC Piston Ring Compressor 3"

The 3-inch piston ring compressor is adjustable to accommodate different piston sizes, offering versatility for various engine types and ensuring a precise fit.

1) Position the compressor over the piston rings on the piston in the cylinder with the rings aligned. 2) Adjust the tool to fit the piston diameter. 3) Engage the positive lock to compress the rings evenly. 4) Slide the piston into the bore and release the lock to release the rings once inside.

It’s built from high-strength spring steel with a corrosion-resistant coating, designed to withstand engine assembly pressures and provide long-term reliability. The design is compact and lightweight for easy handling.

The tool applies even pressure around the piston rings due to its adjustable clamp and spring steel construction, while the beaded lower edge helps prevent the compressor from slipping into the cylinder, reducing the risk of ring damage.

Ideal for engine rebuilds and DIY repairs where piston rings need to be installed or removed in gasoline and diesel engines. It is suitable for both professional shop use and home workshops.

The 3-inch version supports larger ring assemblies and is more versatile for mid-size engines, while the 2.5-inch model fits smaller pistons. If you routinely work with mid-range engines, the 3-inch option may save time and effort. See: https://fepy.com/product/sata-st97500sc-piston-ring-compressor-25

The 3.5-inch model is designed for larger piston rings and bigger bore engines, offering more capacity. The 3-inch version is ideal for mid-range sizes and may be quicker to handle for those engines. See: https://fepy.com/product/sata-st97502sc-piston-ring-compressor-35
