FAQs

What is SAE 100 R4 hose used for?

SAE 100 R4 hose is mainly used for low-pressure hydraulic suction and return lines, including fuel, lubricating oils, and hydraulic oil transfer.

Is SAE 100 R4 hose reinforced with wire?

Yes, it is typically reinforced with a spiral of textile fabric and a wire helix to prevent collapse under vacuum and enhance kink resistance.

Can SAE 100 R4 hoses handle high temperatures?

The standard SAE 100 R4 hose is rated for oil temperatures from -40°C to +100°C. We also offer custom formulations for higher temperature resistance.

Do you offer custom branding or private label?

Yes, we support OEM and private label services, including logo printing, packaging, and customized color stripes.

What sizes are available?

Standard sizes range from 3/4″ to 4″. We can also develop custom inner and outer diameters upon request.

Can I get a free sample before bulk order?

Yes, samples are available upon request. Just contact our sales team to discuss shipping details.
