Frequently Asked Questions
What international standards do your power steering hoses comply with?
Our hoses are manufactured to meet or exceed SAE J188 and SAE J189 standards, ensuring high performance in automotive hydraulic systems.
What materials are used for the construction of these hoses?
The hoses feature an inner tube made of CSM (Chlorosulfonated Polyethylene), a two-layer PA reinforcement for pressure resistance, and an outer cover also made of CSM for excellent ozone and heat resistance.
What is the operating temperature and pressure range?
The hoses can operate in temperatures ranging from -40ºC to +150ºC. They are designed for high-pressure systems with a burst pressure rating between 9400 and 12300 PSI.
Are there different surface finishes available?
Yes, we provide both smooth surface and cloth-wrapped surface finishes depending on your specific requirements or preference.
What sizes are available for the high-pressure power steering hoses?
We produce standard sizes including 1/4", 5/16", 3/8", 1/2", and 5/8" to fit most truck, bus, and passenger car power steering systems.
What is the typical lead time for an order?
Lead times depend on quantity: approximately 40 days for up to 1000 meters, 30 days for up to 5000 meters, and around 25 days for larger orders over 5000 meters.
