High Pressure hoses standards from Jinyuan Rubber

High Pressure Hose Standards

SAE J517 standard remains the benchmark for high pressure hydraulic hose dimensions and performances.

Many hoses offer higher ratings,longer life,and more flexibility than standard hoses of the same size.

SAE hose standards list:

In order to bring a measure of uniformity to hydraulic hoses manufacturer,minimum standards requirement for construction,dimensions,and performances have long been established in North America by SAE.

Except SAE standards,there are some other standards out of North America,such as the European Norm Standard(EN),Deutsche Industrie Norm(DIN),and the International Standards Organization(ISO) also set standards.which may differ from those of SAE.

SAE standard J517 issued general specs for the 100R hose series,which are the most common hoses used in hydraulic systems now.Here is an brief overview of SAE specs.

SAE 100R1, Type A hose has one braid of high-tensile-strength wire around an oil resistant tube (commonly nitrile), and an oil, weather, UV, and ozone-resistant cover commonly made of NBR or PVC. Type AT has the same construction as Type A, except the cover does not need to be removed to assemble with fittings. Type S has the same construction as Type AT and working pressures of ISO 436-1, Type 1SN.

SAE 100R2 hose has two braids of steel-wire reinforcement. A ply or braid of suitable material may be used over the inner tube and/or wire reinforcement to anchor the rubber to the wire. Type A requires skiving (removing) a portion of the cover to assemble with fittings. Type AT has the same construction as Type A, except the cover does not need to be removed to assemble with fittings. Type S has the same construction as Type AT and working pressures of ISO 1436-1, Type 2SN.

SAE 100R3 hose has two braids of synthetic textile yarn. It is generally used in low-pressure applications with petroleum oils, antifreeze, or water.The same construction as EN854 2TE

SAE 100R4 hose has one or more plies of woven or braided textile fibers with a spiral of body wire. It’s typically used for return and suction lines.

SAE 100R5 hose is reinforced with two textile braids separated by a high-tensile-strength steel-wire braided. All of the braids are impregnated with an oil and mildew-resistant synthetic rubber compound.

SAE 100R6 hose includes one braided or spiral ply of textile yarn. It’s for general-purpose, low-pressure applications.

SAE 100R7 thermoplastic hose should be used with synthetic, petroleum, and water-based hydraulic fluids at temperatures from –40 to 93°C. It consists of a thermoplastic inner tube resistant to hydraulic fluids with synthetic-fiber reinforcement and a hydraulic fluid and weather-resistant thermoplastic cover. Nonconductive 100R7 is identified with an orange cover and appropriate layline. Pressure capacity is similar to that of 100R1.

SAE 100R8 high-pressure thermoplastic hose should be used with synthetic, petroleum, and water-based hydraulic fluids within a temperature range from –40 to 93°C. It has a thermoplastic inner tube resistant to hydraulic fluids, synthetic-fiber reinforcement, and a hydraulic fluid and weather-resistant thermoplastic cover. Nonconductive 100R8 is identified with an orange cover and appropriate layline. Pressure capacity is similar to that of 100R2.

SAE 100R9. This hose type has been removed from the SAE standard.

SAE 100R10. This hose type has been removed from the SAE standard.

SAE 100R11. This hose type has been removed from the SAE standard.

SAE 100R12 hose should be used with petroleum and water-based hydraulic fluids within a temperature range from –40 to 121°C. It has four spiral plies of heavy wire wrapped in alternating directions. A ply or braid of suitable material may be used over the inner tube and/or over the wire reinforcement to anchor the synthetic rubber to the wire.

SAE 100R13 hose is for petroleum and water-based hydraulic fluids within a temperature range from –40 to 121°C. Multiple spiral plies of heavy wire wrapped in alternating directions cover the inner tube. It’s for high-pressure applications subject to surges or flexing.

SAE 100R14 hose handles petroleum, synthetic, and water-based hydraulic fluids within a temperature range from –54 to 204°C. Type A consists of an inner tube of polytetrafluorethylene (PTFE) reinforced with a single braid of stainless steel. Type B has the same construction as Type A, but with the additional feature of an electrically conductive inner surface to prevent buildup of electrostatic charge.

SAE 100R15 hose should only be used with petroleum-based hydraulic fluids within a temperature range from –40 to 121°C. It has multiple spiral plies of heavy wire wrapped in alternating directions. A ply or braid of suitable material may be used over or within the inner tube and/or over the wire reinforcement to anchor the rubber to the wire.

SAE 100R16 hose has one or two braids of steel-wire reinforcement. It’s for high-pressure hydraulic applications requiring tight bends and high flexibility.

SAE 100R17 hose, with one or two braids of steel-wire reinforcement, has a constant working pressure rating of 3,000 psi.

SAE 100R18 thermoplastic hose should be used for synthetic, petroleum, and water-based hydraulic fluids in a temperature range from –40 to 93°C. It has a thermoplastic inner tube that resists hydraulic fluids, synthetic-fiber reinforcement, and a hydraulic fluid and weather-resistant thermoplastic cover. Nonconductive 100R18 is identified with an orange cover and appropriate layline. Working pressure rating is 3,000 psi for all sizes.

SAE 100R19 hose has a constant working pressure rating of 4,000 psi in all sizes. It has one or two braids of steel-wire reinforcement. A ply or braid of suitable material may be used over the inner tube and/or wire reinforcement to anchor the rubber to the wire.
