Review on 🔧 Efficient Compression Made Easy: OTC 4838 Piston Ring Compressor Set - 6-Piece by Robin Naber

This is a well built set that is easy to use. Each band is marked for bottoming, and the holding holes are slightly off-center to create a slight taper that gets narrower towards the bottom. The holding hand tool works horizontally or vertically and the ratchet works well. My only complaint is that the bands are powder coated and the paint can chip unless a lot of lube is used on the bands and piston rings. The box is plastic, but well finished, everything is convenient.
