The hoses are manufactured to meet SAE J188 and SAE J189 standards, ensuring compatibility and safety for automotive hydraulic systems.
What materials are used in the construction?
We use CSM (Chlorosulfonated Polyethylene) for both the inner tube and outer cover due to its excellent resistance to ozone, heat, and oil. The reinforcement consists of two layers of high-strength PA (Polyamide) braiding.
What is the pressure rating for these hoses?
Our high-pressure hoses have a burst pressure ranging from 65 to 85 Mpa (9400 to 12300 psi), making them suitable for demanding automotive applications.
Can the hoses handle extreme temperatures?
Yes, the standard operating temperature range is -40°C to +150°C, providing reliable performance in various climate conditions.
Are there different surface options available?
Yes, we offer both Smooth Surface and Cloth (Wrapped) Surface options to meet specific aesthetic or technical requirements.
What sizes are commonly available?
We provide standard sizes including 1/4", 5/16", 3/8", 1/2", and 5/8" to fit most vehicle power steering systems.
