Frequently Asked Questions

What standards do these power steering hoses comply with?
The hoses are manufactured to meet SAE J188 and MS263-53 standards, ensuring reliability for automotive hydraulic systems.
What materials are used for the inner and outer layers?
Both the inside and outside rubber are made of CSM (Chlorosulphonated Polyethylene), which provides excellent resistance to heat, oil, and ozone.
What is the typical burst pressure for these hoses?
The burst pressure typically ranges between 65 to 85 Mpa (approximately 9400 to 12300 psi), depending on the specific size.
Can these hoses be used for both high and low pressure sides?
These specific hoses are designed for the high-pressure side of the power steering system. Low-pressure hoses are available separately.
What are the available surface finishes?
We offer both cloth surface (wrapped) and smooth surface options to meet different aesthetic and functional requirements.
What is the operating temperature range?
The standard working temperature range is -40ºC to +150ºC, making it suitable for most automotive engine environments.
