What Leak Proof Engineering does
Leak-Proof Engineering (India) Private Limited is a Mumbai-headquartered manufacturer of mechanical seals and adjacent sealing components, founded in 1973 as the first company to produce mechanical seals in India. The company's core technology spans mechanical shaft seals (pusher, metal bellow, rubber bellow, fully split, and non-contacting designs) compliant with API 682 and DIN 24960, dry gas seals for centrifugal compressors compliant with API 692, full API Plan-based seal support systems (Plans 11, 32, 52, 53A, 53B, 54, 62, 65A), rotary joints, bearing isolators (IsoPro series), cutlass bearings, flexible graphite packings, self-sealing rings, and segmental carbon seals. Manufacturing is anchored by an 18,000+ sq. mtr. in-house facility in Vadgam, Gujarat, with captive production of silicon carbide and ceramic faces and metal bellow welding, plus dedicated test rigs for API 682, dry gas, agitator, non-contacting, high-pressure/high-speed, and cryogenic seal qualification.
The company sells predominantly through a direct, field-based sales-led motion — 16 branch offices and 7 regional offices across India, supplemented by international sales and service offices in Bangladesh, Saudi Arabia, Nigeria, the United States, Kuwait, and the UAE — with manufacturing/repair facilities in Abu Dhabi (UAE) and Al-Jubail (Saudi Arabia). End markets span 15 industrial verticals, with primary emphasis on Oil & Gas, Refineries, and Petrochemicals, and secondary exposure to Fertilizers, Power Generation, Chemicals, Pharmaceuticals, Mining & Mineral, Steel, Biotech, Cryogenic, Paper & Pulp, Food & Beverage, Textile, and Pigment & Dyes. Revenue mechanics are dominated by one-time product sales of seals and support systems, complemented by refurbishment and repair services performed at facilities in India and Saudi Arabia; pricing is not publicly disclosed and is negotiated through the direct sales organization. The company is privately held, holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, and operates with 501–1,000 employees.
