ABOUT US
CREAVEY SEALS WAS ESTABLISHED IN 1962, A TIME OF ENERGY, INNOVATION AND NEW FRONTIERS, WITH EXCITING PLACES STILL TO BE EXPLORED - NOT LEAST OF WHICH WAS THE MOON!
America's space exploration program had been taking 'giant steps' forward in the 1960's, and William Creavey was one of the innovators keeping pace. He had been conducting experiments with Teflon® and had successfully created a seal that could withstand the extreme temperatures and safety critical applications associated with the aerospace industry. The Teflon®-encapsulated seal, and a whole new industry, were born.
William Creavey's innovation gave the world a reliable way to close off potential leaks between mating surfaces in static and dynamic applications - assisting in keeping the doors of progress well and truly open as engineers could be confident that Creavey sealing solutions would perform superbly in a wide range of applications.
Through the following decades, Creavey Seal Company lead an entire industry, defining encapsulated o-ring technology by developing new designs, materials and processes for applications ranging from outer space to protecting sensitive mechanical parts - including pumps, filters, compressors, vessel lids and pressure regulated valves. Whatever the application, the common denominator was always Creavey's consistency, superb quality and pursuit of perfection.
Today, Creavey Seals is part of the global Integrated Polymer Solutions group, with access to a breadth and depth of advanced skills and superb production facilities. Integrated Polymer Solutions is headquartered in Long Beach, California and also has a European Head office in Yorkshire, England, where NES (Northern Engineering Sheffield) is based.
