Q1: What does KUNGFLEX do?+
Shanghai Beirun Hydraulic Equipment Co., Ltd. (KUNGFLEX) is a source factory for hydraulic hoses and fluid connection components, providing fluid connection solutions across hydrogen energy, semiconductor, wind power, nuclear power, aviation, vehicle manufacturing, production automation, marine, medical, liquid cooling, die casting, injection molding, adhesive dispensing, robotics, metallurgy, mining, and environmental protection. With an in-house production workshop of about 2,000 m2 and ISO 9001:2015 certification, our products are exported to 80+ countries.
Q2: What details should I pay attention to when selecting a hose?+
Key details for hose selection: ① Brand requirement and whether domestic replacement is supported; ② Inner diameter (hose bore); ③ Industry standard (SAE/DIN/GB, etc.); ④ Working pressure requirement; ⑤ Operating temperature range; ⑥ Medium to be conveyed (hydraulic oil, water, chemicals, ethanol, methanol, hydrogen, etc.); ⑦ Bending radius and operating conditions. For hose assemblies, also specify fitting type, sealing form, fitting material, and connection size.
Q3: How do I select the right hydraulic hose for my equipment?+
Selection should consider four factors: ① Working pressure and safety factor (recommended ≥ 4× working pressure); ② Inner diameter (determines flow rate); ③ Medium and temperature (compatibility differs); ④ Bending radius and vibration conditions. Provide your specs and the factory can assist with selection.
Q4: How much pressure can the hose withstand? Do you have burst testing?+
KUNGFLEX ultra-high pressure hose assemblies undergo burst testing up to approximately 4000 kg / 400 MPa — about 10× the standard working pressure — along with pressure hold, impulse, and aging tests to ensure reliability in harsh high-pressure environments.
Q5: What media is the hose compatible with? Can it be used for hydrogen or chemicals?+
Standard rubber hoses suit mineral hydraulic oil, water-glycol, etc. For ethanol, methanol, hydrogen, or corrosive chemicals, select hoses with a suitable inner liner (e.g., PA or special synthetic rubber). Please specify the medium when ordering.
Q6: What certifications do your products have?+
Our company is certified to ISO 9001:2015. Products comply with SAE, DIN, GB and other domestic and international standards, and are delivered with factory test reports.
Q7: Do you support custom and OEM/ODM? What is the MOQ?+
Yes. With a flexible production line and 2,000 m² in-house workshop, we accept drawings and samples for non-standard customization and small-batch flexible delivery. Specific MOQ is determined by specification and customization requirements — welcome to inquire.
Q8: What industries do your products mainly serve?+
Data center liquid cooling piping, semiconductor ultra-high-purity transfer, railway locomotive hydraulic control, wind power hydraulic systems, and energy storage thermal management — covering cooling circulation, hydraulic control, ultra-pure transfer, and thermal management key piping.
