High Pressure Wire Braided Rubber Hose Pipe – Industrial Grade Hydraulic Solution
1. Product Overview
Our wire braided rubber hose pipe is engineered for demanding hydraulic and industrial fluid transfer applications. Constructed with a synthetic rubber inner tube, multiple layers of high-tensile steel wire braiding, and a robust oil- and abrasion-resistant outer cover, this hose delivers exceptional pressure resistance and long service life. Designed to meet or exceed SAE 100 R1, R2, and EN 853 standards, it is the preferred choice for machinery, construction equipment, and oilfield operations where reliability under extreme conditions is non-negotiable.
2. Key Features
- Reinforced Steel Wire Braiding: One or two layers of high-tensile steel wire provide superior burst strength and flexibility, ensuring the wire braided rubber hose pipe withstands high impulse pressures.
- Synthetic Rubber Inner Tube: Oil- and water-resistant NBR or EPDM compound prevents degradation from hydraulic fluids, coolants, and lubricants.
- Abrasion-Resistant Cover: Neoprene or SBR outer layer resists cuts, weathering, and ozone cracking, extending hose life in harsh environments.
- Wide Temperature Range: Operates effectively from -40°C to +100°C (-40°F to +212°F), with intermittent spikes up to +125°C.
- Flexible & Kink-Resistant: Optimized helix design minimizes bend radius, allowing easy routing in tight spaces without collapse.

4. Application Scenarios
The wire braided rubber hose pipe is versatile and used across multiple sectors:
- Hydraulic Systems: Power units, cylinders, and valves in excavators, loaders, and forklifts.
- Construction Machinery: Concrete pumps, road rollers, and drilling rigs requiring high impulse resistance.
- Oil & Gas: Transfer of crude oil, diesel, and hydraulic fluids in refineries and offshore platforms.
- Agricultural Equipment: Tractors, sprayers, and harvesters exposed to UV and abrasion.
- Industrial Manufacturing: Presses, injection molding machines, and material handling systems.
- Mining: Hydraulic roof supports, conveyors, and rock drills in dusty, wet conditions.
5. Advantages
- Superior Pressure Handling: The steel wire braid absorbs peak pressure spikes, reducing risk of hose burst and downtime.
- Extended Service Life: Oil-resistant tube and weatherproof cover minimize premature failure from fluid incompatibility or environmental stress.
- Cost-Effective Maintenance: Fewer replacements and lower leakage rates reduce total cost of ownership.

7. FAQ
Q1: What is the difference between 1-wire and 2-wire braided rubber hose pipe?
A: A 1-wire braid (SAE 100 R1 / EN 853 1SN) is suitable for medium-pressure applications (up to ~210 bar), while a 2-wire braid (SAE 100 R2 / EN 853 2SN) offers double the reinforcement for high-pressure systems (up to ~420 bar). Choose 2-wire for heavy-duty hydraulic circuits with frequent impulse loads.
Q2: Can this hose be used for steam or water?
A: Our standard wire braided rubber hose pipe is designed for petroleum-based hydraulic fluids, air, and water. For steam service, we recommend a specialized EPDM-lined hose. For hot water (below 100°C), the NBR tube is acceptable but verify with our technical team for continuous duty.
Q3: What is the minimum bend radius, and why does it matter?
A: The minimum bend radius varies by hose size – typically 5 to 8 times the inner diameter. Exceeding this radius can cause kinking, reduce flow, and damage the wire braid. Always follow the specification sheet to maintain pressure rating and service life.
Q4: How do I select the correct hose size for my system?
A: Match the hose inner diameter (ID) to the port size of your fittings. Consider flow rate, system pressure, and length. Oversizing increases cost and weight; undersizing creates excessive pressure drop. Use our online calculator or contact our engineers for sizing assistance.
Q5: Do you offer custom end fittings or pre-assembled hoses?
A: Yes. We provide crimped or reusable fittings in steel, stainless steel, and brass. Pre-assembled hoses with pressure testing and labeling are available for OEM orders. Minimum order quantities may apply for custom assemblies.
Q6: What is the shelf life of this wire braided rubber hose pipe?
A: Under proper storage conditions (cool, dry, away from direct sunlight and ozone), the hose retains its performance for up to 5 years from the date of manufacture. Always inspect before installation.
Note: Specifications are typical values and may vary with size and custom configurations. Always consult the product data sheet for exact ratings. For technical inquiries or bulk pricing, contact our sales team.
