Our legacy
55+
A legacy of engineering.
A future built around water.
Since 1970, Krishna Auto Industries has evolved from a precision engineering enterprise into a specialised manufacturer of products for water transmission, distribution and flow control.
Through LnT ductile iron fittings and KRIMCO resilient seated sluice valves, we combine decades of manufacturing knowledge with a clear long-term purpose: supporting reliable water infrastructure.
