The Micro-Tec Ring Squeezer 90–175mm (Long Series) is a premium piston ring compressor designed for fast, safe and precise installation of piston rings—especially on heavy-duty skirt ring pistons. Manufactured from highest-grade spring steel, this long-series compressor delivers exceptional strength, consistent clamping pressure and long service life. With a positive locking action, dual tension bands and a built-in safety valve friction brake, it prevents premature release while ensuring smooth, controlled compression. The wide capacity range allows the band to compress all rings at once, including skirt rings, making it ideal for professional engine builders and workshop technicians.
