About us

Leak Proof has made significant contributions to the Indian Process industry. first in 1973 to manufacture mechanical seals.. first in 1983 to introduce flexible graphite, gaskets, packing and self sealing rings.. first to install facilities for manufacture of Silicon Carbide and High Alumina Ceramic seal faces, first to cartridgise heavy duty feed pump seals.. and so on. The pioneering spirit pervades our business philosophy even today. We believe in quality and class in engineering excellence rather than volumes.This is reflected in our predominant position in the higher end seals market in India. And, in the remarkable successes of our innovative application engineered seals, even in the most severe duty conditions. Our seal series LPA90S & LPA47S API 682 Seals developed indigenous for Petroleum Refinery and Oil & Gas Industry, series LPG901 Dry Gas Seals for Compressors, series LPKS918 for Agitated Nutsche Filters, series LPH 5149 for Concrete Volute Pumps, series 800 HB2 in Boiler Feed Pumps; series 90B35 in turbulent slurry applications; series 900B in heavy duty pipe line pumping; have made significant impact in the Indian industry and abroad in Argentina, Australia, Brazil, Canada, Colombia, UAE, Egypt, France, Germany, Indonesia, Iran, Jordan, Kuwait, Malaysia, Norway, Oman, Puertorico, Russia, Saudi Arabia, Spain, U.K., U.S.A., Venezuela, Etc. Our Modern Manufacturing facilities at North Gujarat has greatly strengthened our capabilities to take on large requirements, at quick delivery schedules. With our complete range of mechanical seals of all types and sizes and the everreliable Grafoil range of gaskets & packings we have an enviable reputation for reliable industrial sealing products, in India and abroad.
