NBR Rubber Hose
Product Overview
The NBR rubber hose is a premium-grade hydraulic and industrial hose engineered from Nitrile Butadiene Rubber (NBR), a synthetic elastomer celebrated for its exceptional resistance to oils, fuels, petroleum products, and a wide array of industrial chemicals. This robust hose construction ensures reliable performance in demanding environments where exposure to harsh fluids is constant. Ideal for high-pressure applications, our NBR rubber hose features a seamless inner tube that minimizes fluid permeation, a reinforced synthetic textile braid or steel wire helix for superior strength, and an oil-resistant NBR cover that withstands abrasion, weathering, and ozone degradation.
Manufactured to international standards such as SAE 100R6, DIN 20022, and ISO 1436, the NBR rubber hose delivers consistent pressure ratings up to 400 bar, depending on the diameter and construction. Its flexibility across a broad temperature range—from -40°C to +100°C—makes it versatile for automotive, agricultural, construction, and manufacturing sectors. Whether conveying hydraulic fluids, diesel fuel, or lubricants, this hose provides leak-proof operation, extending equipment lifespan and reducing downtime. Available in various lengths, diameters, and end fittings, our NBR rubber hose supports custom configurations to meet specific project requirements, ensuring seamless integration into existing systems.
With advanced compounding techniques, the NBR rubber hose exhibits low compression set and high tensile strength, preventing kinking and bursting under impulse pressure cycles. This makes it a go-to solution for professionals seeking durability without compromising on cost-efficiency. Backed by rigorous quality testing, including hydrostatic burst tests and adhesion checks, every meter of our NBR rubber hose guarantees safety and longevity in real-world applications.

FAQ
What is an NBR rubber hose?
An NBR rubber hose is constructed with Nitrile Butadiene Rubber, offering high resistance to oils, fuels, and abrasion. It's widely used in hydraulic and fuel transfer systems for its balance of flexibility and strength.
How does NBR rubber hose differ from EPDM or SBR hoses?
Unlike EPDM (water-focused) or SBR (general-purpose), NBR excels in oil and petroleum resistance, making it unsuitable for water but ideal for industrial fluids. It provides better low-temperature flexibility than neoprene alternatives.
What is the maximum working pressure for NBR rubber hose?
Working pressure ranges from 50 to 400 bar based on size and reinforcement. Always refer to the specification table and match to your system's requirements for safety.
Can NBR rubber hose handle biofuels or synthetic oils?
Yes, standard NBR grades are compatible with most biofuels (up to B20) and synthetic hydraulic fluids. For aggressive synthetics, consult our technical team for specialized compounds.
What maintenance is required for NBR rubber hose?
Inspect regularly for abrasions, kinks, or leaks. Store away from direct sunlight and chemicals. Replace if exposed to temperatures beyond specs or after 5 years, whichever comes first.
Are custom lengths and fittings available for NBR rubber hose?
Absolutely. We offer cut-to-length reels, pre-assembled crimped ends, and adapters in carbon steel, stainless, or brass to fit your exact specifications.
Does your NBR rubber hose meet international safety standards?
