Grandflex Oil Suction and Discharge Hose Overview
Grandflex Oil Suction and Discharge Hose is a heavy-duty suction & delivery hose engineered for transferring, sucking and discharging fuel oil, diesel oil and a wide range of petroleum products with aromatic content up to 50%. Constructed with NBR inner tube, multi-layer high tensile textile cord reinforcement integrated with helix steel wire and anti-static wire, plus NBR+CR rubber outer cover. It is built to endure full vacuum suction, prevent hose collapse, dissipate static electricity and withstand tough on-site working conditions. With an operating temperature range of -20℃ to 80℃ and size options from 3/4" to 8", this hose is widely used for tank trucks, oil depots, storage tanks and all kinds of industrial petroleum transfer systems.

Oil Suction Discharge Hose Description for Petroleum Transfer Service
In oil transfer service, hose performance relies not only on pressure rating, but also on vacuum resistance, anti-collapse property and long service durability. The suction & discharge hose must keep stable flow under full vacuum suction while enduring repeated dragging, bending and repositioning on site. If the hose collapses easily under vacuum, suffers poor oil resistance or ages quickly, the oil transfer efficiency and service life will be heavily affected.
This hose is designed to solve those operational challenges with oil-resistant NBR inner tube, helix steel wire reinforced structure for vacuum support, and durable NBR+CR outer rubber cover for weather and abrasion protection. Compared with general-purpose rubber hoses, it performs much better for petroleum media suction and delivery, especially for scenarios requiring vacuum resistance, oil resistance and flexible field handling at the same time.
Product Details
Key Advantages of Oil Suction & Discharge Hose
Excellent Oil Resistance & Vacuum Performance
- NBR inner tube delivers outstanding resistance to diesel, fuel oil and petroleum derivatives
- Built-in helix steel wire prevents collapse under full vacuum suction
- Handles continuous suction and discharge of oil-based media reliably
Working Stability in Oil Transfer Operations
- Multi-ply high tensile textile cord reinforcement maintains working pressure steadily
- Anti-kink structure guarantees consistent media flow during operation
- Adaptable to rough site conditions with frequent dragging and movement
Operator and System Value
- Integrated anti-static wire avoids static accumulation for safer oil transfer
- Maintains good flexibility for easy routing while keeping robust structure
- Reduces downtime caused by hose collapse, oil swelling or premature aging
- Perfect for oil delivery systems on tank trucks, depots and industrial facilities
