The Sealey VS157 Piston Ring Compressor with 60mm-175mm diameter capacity is specifically designed for medium to larger bore engines, making it ideal for performance vehicles, larger capacity family cars, and light commercial applications. The 60mm minimum diameter makes this model particularly well-suited to engines where smaller compressors simply won't fit. The quality construction features sprung steel wraps that maintain consistent pressure around the piston circumference, whilst the ratchet action tension mechanism allows for precise, graduated tightening. This combination ensures that even on larger pistons, you achieve uniform compression without risking damage to expensive rings. The supplied steel key provides convenient control over the tension adjustment.
