Product description
The R4 Low-Pressure Suction & Return Hose is a textile-reinforced hose with a helical wire that prevents collapse under suction. Conforms to SAE 100R4.
Construction
- Tube: Synthetic rubber (NBR), oil-resistant
- Reinforcement: Heavy textile braid plus spiral helix wire (anti-collapse)
- Cover: Synthetic rubber, oil and weather-resistant, cloth-impression finish
Performance
Working pressure, as published by the manufacturer: 21 bar at 3/4", 17 bar at 1", 14 bar at 1-1/4", 10 bar at 1-1/2" and 7 bar at 2", with minimum burst four times working pressure. Continuous service from -40°C to 121°C — ask for a fluid compatibility chart if running aggressive fluids.
Applications
- Hydraulic suction lines from reservoir to pump
- Low-pressure return lines back to tank
- Charge-pressure circuits and lubrication delivery
Compliance
- SAE 100R4

Supply — Length and packaging the part number is supplied in, as published. Ask us for the dimension drawing if you need it stamped.
Working pressure is the manufacturer’s published rating for the fitting itself. An assembly is limited by its lowest-rated component, so check it against the hose, the tube and the port you are mating to.
