How to Choose Fuel Oil Hose SAE J30 R6 for Size and Service Conditions

Start with the fluid

Fuel Oil Hose SAE J30 R6 is made for diesel, petroleum products, gas oil, biodiesel, hydraulic oil, mechanical oil, lubricating oil and fuel service. We use a black, smooth NBR rubber tube, high-strength synthetic yarn reinforcement and an oil-resistant synthetic nitrile rubber cover. This combination suits a fuel or oil route where the hose is exposed to the conveyed medium over time.

The product is intended for oil with less than 30% aromatic substance content, while its application description covers petroleum-based products with aromatic content up to 50%. Treat aromatic content as an ordering point: send the exact fluid name and composition so we can review the proposed hose for your service.

Choose bore with pressure in view

Select the inside diameter from the equipment connection and the flow path, then check the pressure assigned to that size. The range is 5 mm to 50 mm. Working pressure is 20 bar for 5 mm through 25 mm, 15 bar for 32 mm, and 10 bar for 38 mm and 50 mm. Burst pressure is 60 bar for the 5 mm through 25 mm sizes, 45 bar for 32 mm, and 30 bar for 38 mm and 50 mm.

A 5 mm to 25 mm bore is the appropriate group when the connection and flow requirement also call for 20 bar working pressure. The 32 mm option is for a larger passage where 15 bar is enough. The 38 mm and 50 mm options suit the largest passages in this range when the system requirement stays within 10 bar working pressure.

Check the route, weight and temperature

Outside diameter determines whether the hose can pass through the available clamps, brackets and openings. A 25 mm inside diameter has a 35 mm outside diameter and weighs 0.78 kg per meter. A 50 mm inside diameter has a 65 mm outside diameter and weighs 1.7 kg per meter. Measure the route and consider the supported hose weight before choosing a large bore for a replacement or transfer line.

The service temperature range is -20°C to 80°C. Compare the lowest and highest temperatures around the hose with this range, especially near fuel equipment, engines or outdoor sections. Include the connection area and bend path in the clearance measurement, since the outer diameter only describes the hose body.

Roll length affects cutting and handling. The 5 mm through 10 mm sizes are supplied in 100 ±1% meter rolls. The 12.7 mm through 32 mm sizes are supplied in 50 ±1% meter rolls. The 38 mm and 50 mm sizes are supplied in 30 ±1% meter rolls. A maintenance order should include the required cut length and quantity; a distributor should plan storage around the roll size and weight per meter.

Match the product to the purchase situation

For a compact fuel or oil line, select the bore that matches the connection while keeping the required pressure within the size group. The smaller sizes combine 20 bar working pressure with outside diameters from 11 mm to 35 mm, so they fit routes where both pressure and clearance matter.

For a larger transfer path, 32 mm, 38 mm and 50 mm provide progressively larger inside diameters, but their working pressure drops to 15 bar or 10 bar. A 50 mm hose needs 65 mm of body clearance and weighs 1.7 kg per meter. Measure the opening, support spacing and connection before specifying it.

Our material construction remains the same across these sizes: NBR tube, synthetic yarn reinforcement and oil-resistant synthetic nitrile rubber cover. The purchase decision changes with fluid, aromatic content, bore, pressure, temperature, route clearance, required cut length and order quantity. Send those details together so we can review the complete selection.
