The NBR (nitrile) inner tube of SAE 100R2AT provides excellent resistance to petroleum-based fluids. Always confirm fluid compatibility before use.
SAE 100R2AT hydraulic hose is a global standard for high-pressure fluid transmission across virtually every mobile and stationary hydraulic application.
Performs reliably in the outdoor environments typical of forestry equipment, utility vehicles, and municipal machinery.
Used in stationary and mobile industrial hydraulic power units, presses, machine tools, and automated systems.
ISO 9001:2015 Certified Factory
Our production facility in Qingdao operates under a certified quality management system. Every batch of SAE 100R2AT hose undergoes dimensional inspection, burst pressure testing, and impulse cycle validation before shipment.
10+ Years of Global Export Experience
We export to distributors, OEM manufacturers, and hydraulic hose assembly shops in over 60 countries including the USA, Germany, Australia, UAE, Brazil, and Southeast Asia. Our team understands international shipping, customs documentation, and compliance requirements.
OEM & Private Label Available
We print your brand name, part numbers, and specifications directly on the hose cover. Custom color covers, non-standard coil lengths, and unique packaging are all available. Ideal for distributors looking to build a branded product line.

SAE 100R2AT is a high-pressure hydraulic hose defined by the SAE J517 standard. It consists of three layers: an oil-resistant NBR (nitrile) rubber inner tube, two braids of high-tensile steel wire reinforcement, and a thin oil- and weather-resistant synthetic rubber outer cover. The “AT” designation indicates an Armored Thin cover — meaning the cover is thin enough to be directly crimped over with swaged fittings, without the need to strip or skive the outer rubber beforehand.
The difference is cover thickness and fitting installation method. SAE 100R2AT has a thin rubber cover — crimp or swaged fittings are applied directly over the cover with no preparation needed. SAE 100R2A has a thicker rubber cover, offering greater abrasion resistance for exposed installations, but requires the outer cover to be skived (stripped back) before a fitting can be properly installed. Both hoses use the same two-braid steel wire reinforcement and have identical working pressure ratings.
The working pressure varies by inner diameter. The highest pressure is for the smallest bore — a 1/4″ (DN6) hose is rated at 400 bar (5,800 psi) working pressure. Larger bores have lower pressure ratings: 3/8″ = 330 bar, 1/2″ = 275 bar, 3/4″ = 215 bar, 1″ = 165 bar. The minimum burst pressure is always 4× the working pressure. See the full specifications table above for all sizes.
Yes — they are cross-equivalent standards from different regions. SAE 100R2AT is the North American standard (SAE J517); DIN EN853 2SN is the European standard for the same hose construction. Both specify a two-wire braid hose with essentially identical dimensional tolerances and pressure requirements. Kingdaflex’s SAE 100R2AT hose meets both SAE 100R2AT and EN853 2SN requirements and can be used interchangeably in systems designed to either standard.
SAE 100R2AT hose with an NBR (nitrile) inner tube is compatible with: petroleum-based hydraulic fluids, mineral oils, diesel fuel, lubricating oils, water-glycol hydraulic fluids (HFC), and synthetic ester fluids (HEES). It is not suitable for phosphate ester-based fluids such as Skydrol or Fyrquel — PTFE-lined hose (SAE 100R14) should be used for those applications.
The continuous operating temperature range is −40°C to +100°C (−40°F to +212°F). Short-term intermittent peak temperature is +120°C. The hose is not suitable for steam applications — for steam service, Kingdaflex offers dedicated steam hose products.
