PME API 7K Hoses Grade D WP 5000 Psi
Our API 7K Grade D rotary drilling hose is specifically engineered to meet the rigorous demands of modern oil and gas drilling.
Designed for high-pressure applications, this hose serves as a critical flexible connection between the standpipe and swivel, or between the mud pumps and standpipe, ensuring efficient and safe fluid transfer on drilling rigs.
With a formidable 5000 PSI working pressure, it delivers exceptional performance and reliability in the toughest operational environments.
Built to comply with the stringent API Spec 7K standards, our Grade D hose provides superior resistance to abrasion, oil, and harsh weather conditions, guaranteeing a long service life and reduced downtime.
It’s the ideal solution for high-pressure mud hose applications and essential for any drilling operation requiring robust and dependable fluid conveyance.




Key Feature
