High Pressure Oil Resistant Rotary Drill Hose 3 Inch for Petroleum Hydraulic Fluids
3 Inch Rotary Drilling Hose - Oil Resistant, Anti-Kink, Extended Service Life, Durable Construction
Rotary drilling hose is a high-pressure flexible hose designed to deliver drilling fluid (mud) between the mud pump and the top drive or rotary swivel in oil and gas drilling operations. Built with multiple steel wire layers and a synthetic rubber cover, it resists abrasion, vibration, and high pressure.
It operates reliably in harsh environments with temperature ranges from -40°C to +120°C and pressure ratings up to 7,500 psi. Anti-kinking structure and flame-retardant cover ensure both durability and operational safety.
