These pipe fitting elbows are manufactured to GOST 13977-72, a Russian standard covering detachable pipeline connections for demanding hydraulic and pneumatic systems. The fittings serve nominal pipe diameters from 3 to 38 mm and withstand working pressures in the 15–24 MPa class, handling media including AMG-10 hydraulic oil, MVP oil, glycerin-alcohol mixtures and compressed air per GOST 17433.
Material options span carbon steel grade 45, alloyed 30KhGSA, stainless grades 14Kh17N2 and 12Kh18N9T, heat-resistant 13Kh11N2V2MF and aluminium alloy AK6 — allowing buyers to match corrosion and temperature requirements precisely. At roughly USD 3 per piece with a 100-piece minimum, the elbows target distributors of hydraulic components, aviation and machine-building MRO suppliers, and plants maintaining equipment built to GOST documentation.
