John Crane

John Crane has a strong legacy that dates back to the creation of the Crane Packing Company in 1917. Prior to World War II, the company’s England-based operations were sold to Tube Investments, which resulted in the creation of TI Group. Then in 1987, TI Group acquired the remaining regional operations and the company reunited as John Crane — named after one of the company’s original founders. In 2000, TI Group merged with Smiths Industries to become Smiths Group plc, a global technology company based in London. Today, John Crane is the largest subsidiary of Smiths Group plc.  1930s–1970s — John Crane has achieved many landmark successes through the years, including the design of the world’s first automotive mechanical seal in 1949. The innovative design was soon followed by the development and introduction of the John Crane Type 1, end-face, elastomer bellows shaft seal. This patented product revolutionized sealing technology and is still one of the most widely used seals in the industry.John Crane still offers the mechanical packing and gasket products upon which the Crane Packing Company built its success. Each year, the company manufactures some 238,900 miles of braided packing — almost enough to reach to the moon — along with flat gaskets and live-load packing for valves.
