High-pressure oil transfer often brings risks of burst, seepage, and accelerated ageing – hazards that threaten both equipment and personnel. Our multi-layer steel wire braided explosion-proof hose is purpose-built to eliminate these dangers.
The Multi-layer Steel Wire Braided Explosion-proof Oil Hose features 4–6 layers of high-tensile steel braid, delivering working pressure up to 70 MPa and burst pressure at least 4 times that, a safety margin that gives plant managers and fleet operators real peace of mind. Inside, a specially formulated NBR tube resists swelling and hardening even after prolonged contact with crude, diesel, or hydraulic oils (ASTM D471 compliant). Outside, a weather-proof cover withstands UV, ozone, and abrasion, extending replacement intervals to 5+ years.
For buyers who value uptime and low total cost, this hose offers a proven combination of durability and safety. We invite you to order a sample, customise length/fittings, or ask for a bulk quotation. Our technical team is ready to advise on proper sizing and installation for your specific application.
Multi-layer Steel Wire Braided Explosion-proof Oil Hose directly addresses the top three concerns in oil delivery: explosion risk from pressure surges, leakage from inner tube degradation, and premature outer cover failure due to harsh environments.
The multi‑layer braid provides a higher safety factor than standard two‑wire hoses – ideal for mobile equipment, stationary pumping stations, and transfer terminals.
Flexible design with a minimum bend radius as low as 180 mm allows easy routing around machine frames and through tight spaces without kinking.
We offer full traceability from raw material to finished product, with each batch pressure‑tested and inspected to meet international standards.
crude oil, refined product transfer lines, tank truck loading/unloading – anti‑static versions available.
excavator boom lines, loader steering circuits, crane telescopic cylinders – handles shock loads and outdoor exposure.
underground roof supports, drilling jumbos – resists impact, moisture, and abrasive dust.
dispenser hoses, aviation refuellers – with static dissipative compounds and wear‑resistant covers for daily heavy use.
4 to 6 layers of high‑carbon steel wire, engineered to distribute pressure evenly; working pressure range 10–70 MPa, burst pressure 4–5 times working pressure – ensuring no catastrophic failure even under severe surges.
Nitrile rubber (NBR) with volume swell ≤ ±10 % after 168 h immersion per ASTM D471 – compatible with mineral oils, diesel, hydraulic fluids, and many synthetic lubricants.
functions from –40 °C to 120 °C without hardening or softening – suitable for arctic cold and desert heat alike.
minimum bend radius ≤ 180 mm (for 6 mm ID) – passed 100,000 impulse cycles without leakage, reducing stress at connection points.
weather‑resistant cover resists cracking, chalking, and abrasion; typical service life ≥ 5 years under recommended conditions – significantly lowers replacement frequency and maintenance costs.

Safety first: Never exceed rated working pressure or temperature. Protect the cover from sharp edges and abrasive contact. For anti‑static requirements, ensure proper grounding of fittings to dissipate static charge.
Routing: Maintain the recommended minimum bend radius at all times; avoid twisting, crushing, or pulling the hose excessively, as this may damage the steel braid.
Inspection: Check regularly for bulges, cuts, or seepage around fittings. Replace immediately if any abnormality is found.
Storage: Keep in a cool, dry place away from direct sunlight, ozone sources, and strong acids/alkalis. Long exposure to harsh chemicals will shorten service life – consult us if your media is aggressive.
Q: What is the minimum order quantity? Can I test a short piece first?
A: Our MOQ is only 10 metres for standard sizes, which makes it easy for you to run a field trial before committing to larger volumes. We also offer sample lengths (up to 2 m) at a nominal fee – refundable upon placing a formal order.
Q: Do you provide custom diameters, lengths, or pre‑installed fittings?
A: Yes. We support full customisation – inner diameter, overall length, pressure rating, and even fitting types (JIC, BSP, flange, etc.). We can also print your logo on the cover for easy identification. Just share your drawing or requirements with our engineers.
Q: How long is the warranty?
A: We offer a 12‑month warranty against material or workmanship defects. If a hose fails under proper use within that period, we replace it free of charge. We also provide failure analysis assistance to help you prevent recurrence.
Q: Is this hose suitable for anti‑static applications?
A: Yes. We can incorporate conductive materials into the inner tube and cover to meet standard resistance requirements (≤ 10⁶ Ω per metre) – ideal for refuelling and solvent transfer. Please specify “anti‑static” when you inquire.
Q: How do I select the correct working pressure grade?
A: Our technical team will guide you based on your maximum system pressure, pressure spikes, and hose length. We recommend choosing a hose with working pressure at least 20 % higher than your normal operating pressure for an added safety buffer.
Q: What is your typical lead time for bulk orders?
A: For standard sizes in stock, shipment within 3–5 working days. Custom orders usually take 10–15 days, depending on quantity and complexity. We also offer expedited production for urgent projects – just ask us.
Q: Can I get a quotation with shipping to my country?
A: Absolutely. Provide your required sizes, quantities, and destination port/address. We will send a detailed proforma invoice with freight options. We also assist with customs documentation.
