Description
Overview:
The Sealey VS155 Piston Ring Compressor is a sprung steel band tool for compressing piston rings so a piston can be installed smoothly into the cylinder bore. Built from durable sprung steel with a ratchet tensioning mechanism and supplied steel winding key, it provides controlled, even compression across the ring set. It covers a seal range of 60-125 mm (2.36-4.92 inches) and is described with a 75 mm (2.95 inches) diameter, suiting a wide spread of small to medium engines. Ideal for work on car and van engines, motorcycles, lawn mowers, generators and other petrol or diesel plant within its size range. A practical choice for engine assembly, rebuilds and maintenance where reliable ring compression is required.
