About

John Crane is the world’s largest designer, manufacturer and supplier of engineered sealing systems and associated products. Our beginnings go back to 1910, when maintenance mechanic John Crane discovered that combining metal foil with packing dramatically improved the performance of packing used to seal pumps on central heating systems he maintained. That innovative spirit formed a basis for the company he founded and has propelled John Crane to a host of breakthrough products and technologies that have revolutionized the sealing industry.
Today, John Crane offers the widest range of sealing products and technological resources anywhere, with more than 50 active patents and a global sealing database of over a half-million applications.
