Piston Ring Set 2.953 1.2 1.5 2.8mm

The Hastings Piston Ring Set 2.953 1.2 1.5 2.8mm is a crucial internal engine component designed for restoring compression, oil control, and ring seal integrity in reciprocating engines. Ideal for mechanics involved in rebuilding or refreshing engine blocks, this set addresses issues like blow-by, loss of compression, and excessive oil consumption.

This piston ring set features precise dimensions with a bore diameter of 2.953 inches and three individual ring thicknesses—1.2mm for the compression ring, 1.5mm for the scraper ring, and 2.8mm for the oil control ring. Each ring is crafted from high-carbon steel, ensuring controlled ring gap geometry for optimal sealing pressure against the cylinder wall during combustion while maintaining the necessary oil film thickness for lubrication.

Technicians restoring engines with the Hastings Piston Ring Set will appreciate the precision engineering that guarantees compatibility with OEM pistons and ring grooves, making it essential for any thorough engine overhaul or top-end rebuild where ring wear cannot be overlooked.
