Back in 1936. Then a product was developed and patented, which today is the main one for the Gebo company. Namely, a ductile iron clamp connection that allows the connection of steel pipes without the use of welding or threading. For more than 80 years, Gebo fittings have been helping people save time and money, and the Gebo brand itself has become a household name. We have been working in Russia for 20 years!!!
