One of the greatest contributions to change, during this last century, has been the internal combustion engine. The story of the Hepworth's is largely the story of this revolution. Since 1907 the name Hepworth has been synonymous with piston manufacturing. Peter was the fourth generation to go into the family business, founded by his great-grandfather in 1907. The company developed the Hepolite piston, famous throughout the world.

In 1977 Peter Hepworth set up a separate organisation (Peter Hepworth Components) concentrating on specialist small batch production. In 1993 Peter Hepworth Components achieved the international standards BS ISO 9002 which was upgraded in 2002 to ISO 9001:2000.

Another success story has been achieved with Peter Hepworth Components now supplying some of Britain's major car manufacturers, compressor manufacturers, the rail industry, and the Ministry of Defence.

In addition the company remains committed to the Classic Car Market – supplying pistons, pins, rings, cylinder liners and engine bearings for Rolls-Royce, Bentley, Aston Martin, Daimler, Jaguar, Bristol and Alvis to name but a few. The company's huge library of drawings together with foundry work, modern machining methods and advanced technology create a product for long life and engine efficiency.
