SAE Male 90 Degree Cone Hydraulic Hose Fitting: Series 17811 (SAE J513)

Why This SAE Male 90 Degree Cone Fitting Passes the Compliance Gate

Series 17811 is a SAE male 90 degree cone hydraulic hose fitting built to SAE J513, the North American 45 degree flare standard for hydraulic connections. The cone is machined with a 90 degree included angle (45 degrees per side) and seals metal-to-metal against a matching female 45 degree cone seat. No O-ring, sealant or thread-seal tape is required, which simplifies stock control and removes a common leak point on OEM machines and field repairs.

• For OEM designers: this SAE male 90 degree cone hydraulic hose fitting follows SAE J513 geometry, straight UNF threads match standard SAE 45 degree flare ports, and every batch is traceable from incoming steel to final test.
• For distributors and wholesalers: one matrix covers hose dash -04 to -12 with a braided-hose listing and a clear spiral-hose variant, reducing SKU guesswork.
• For maintenance teams: the cone seal is forgiving to repeated assembly, needs no consumables, and a damaged cone is obvious before installation.

Core Advantages

1. This SAE male 90 degree cone hydraulic hose fitting relies on SAE J513 45 degree flare geometry: a precision 90 degree male cone pressing into a female 90 degree cone seat, metal-to-metal, with no O-ring or sealant.
2. Full straight fitting matrix: hose dash -04 to -12, nominal bores DN6 to DN20, and thread sizes from 7/16″X20 up to 1.1/16″X14.
3. Hose barb tail suits standard braided hose; the same fitting profile is available as 17812-XX-XX for spiral hose.
4. HENGHUA process package: cold-headed carbon steel or stainless options, consistent heat treatment, 100% pressure testing and thread gauging.

Technical Specifications

What Is a SAE Male 90 Degree Cone Fitting?

The SAE male 90 degree cone hydraulic hose fitting is the male half of the SAE 45 degree flare (SAE J513) connection system, widely used in mobile hydraulics, agricultural equipment and industrial machinery. The term “90 degree cone” describes the male cone whose included angle is 90 degrees, which is why the fitting is also called a 45 degree flare male fitting. It mates with a female 90 degree cone seat on the port or on a companion fitting, and the two machined surfaces form the seal.

This system is not interchangeable with JIC 37 degree (SAE J514) or DIN cone connections even when the thread looks similar. Always confirm the cone angle before assembly, because a 45 degree cone will not seal against a 37 degree seat.

Dimensional Data

Dimensions A, C and S1 are in millimeters as dimensioned on the drawing.

Full Dimension Table (Part Number Matrix)

The table below is transcribed from the HENGHUA Series 17811 specification drawing. Each row is one complete fitting: thread dash and hose dash are identical on this straight series, so the part number reads series-thread dash-hose dash.

Note from the drawing: the part numbers listed are for braided hose; for spiral hose, change the series number to 17812-XX-XX with the same thread and hose dash.

Material and Heat Treatment

Working Pressure and Operating Envelope

The working pressure of a hose assembly is decided jointly by the hose construction and the connection standard; the fitting end itself is produced and pressure-tested to the SAE J513 envelope. Every HENGHUA fitting passes a 100% factory pressure test, and the torque and crimp data sheet for your hose type is supplied with each order. Typical service temperature is -40°C to +120°C, with system de-rating dependent on the hose and any elastomeric seal in the circuit.

Selection and Ordering

How to Read the Part Number Matrix

The part number is built as series-thread dash-hose dash, for example 17811-12-12. The first group, 17811, is the braided-hose series of this SAE male 90 degree cone hydraulic hose fitting; use 17812 for the spiral-hose version. The middle dash identifies the thread end (12 = 1.1/16″X14) and the last dash identifies the hose bore (12 = dash -12, DN20). On the straight Series 17811 the two dashes always match in the standard matrix, so confirm thread size and hose size on one line.

Thread Size and Dash Chart

Cross Reference Service

Send us the old part number from your machine or hose assembly and we will translate it into the correct HENGHUA series, thread and hose dash. For an accurate match, provide the thread size, the hose inner diameter or dash, and a photo or drawing of the end. OEM and private-label marking is available for volume programs.

Packaging and Logistics

Fittings are packed 10 pieces per box with the batch number printed on the carton, and full cartons are palletized for export. Products are marked Made in China by HENGHUA, and the material test report (MTR) accompanies each shipment. Inquiry lead time is confirmed in writing within 24 hours.

Assembly and Use Guide

Four-Step Crimping Procedure

1. Cut the hose end vertically with a sharp hose cutter so the end face is square.
2. Mark the insertion depth on the hose according to the crimp data sheet.
3. Apply a thin layer of assembly lubricant and push the hose onto the barb to the depth mark.
4. Crimp with the correct die set, then verify the crimped outside diameter with a caliper against the data sheet value.

Connecting the Male 90 Degree Cone End

When assembling a SAE male 90 degree cone hydraulic hose fitting, wipe the male cone and the mating female 90 degree cone seat clean and dry, and inspect both surfaces for scratches or dents before assembly. Run the nut or companion fitting up by hand, then tighten to the torque given on the HENGHUA data sheet for your size. No O-ring, sealant or thread-seal tape is used on this connection, and the cone seal must stay free of contamination.

Installation Warnings

• ❌ Never tighten a SAE 45 degree cone into a JIC 37 degree seat or a DIN cone seat; the angle mismatch prevents sealing and can damage both parts.
• ❌ Do not wrap thread-seal tape around the cone or threads; loose fragments contaminate the hydraulic system.
• ❌ Do not install a cone with visible scratches, nicks or embedded dirt.
• ✔ Keep the cone dry and clean until the moment of assembly.
• ✔ Tighten to the data sheet torque, not to “as tight as possible”.

FAQ

What is a SAE male 90 degree cone hydraulic hose fitting?

It is the male end of an SAE 45 degree flare (SAE J513) connection, machined with a cone whose included angle is 90 degrees, so the industry calls it a male 90 degree cone end. The cone seals metal-to-metal against a female 45 degree cone seat without any O-ring or sealant.

How do I tell SAE 45 degree flare (J513) from JIC 37 degree (SAE J514)?

Measure the included angle of the cone: the SAE J513 cone is 90 degrees (45 degrees per side) while the JIC cone is 37 degrees. Both use straight UNF threads, so thread size alone cannot tell them apart; always verify the cone angle before assembly.

Can a 45 degree cone fitting be used with a JIC 37 degree port?

No. The two cone angles are different, so the surfaces cannot seat and the joint will leak or damage the cones. Confirm that the port and the fitting belong to the same system, SAE J513 versus SAE J514, before installation.

Does this fitting need an O-ring or sealant?

No. The SAE J513 45 degree flare design is a metal-to-metal cone seal, and no O-ring, liquid sealant or thread-seal tape is allowed on the cone. Keeping the cone clean and dry is what guarantees a leak-free joint.

Which hoses does Series 17811 fit?

Series 17811 fits braided hose in dash sizes -04 to -12. If the assembly uses spiral hose, order the same fitting as 17812-XX-XX as noted on the dimension drawing.

What female fitting or port does this male cone connect to?

It connects to any SAE J513 female 90 degree cone seat with the matching thread, for example a 45 degree flare female port or a female cone seat fitting such as HENGHUA Series 27811.

What is the pressure rating of this fitting?

This SAE male 90 degree cone hydraulic hose fitting is rated by the combination of the hose construction and the connection standard rather than by a single part number. HENGHUA performs a 100% factory pressure test on every fitting and provides the torque and crimp data sheet with each order.

Can HENGHUA make a private-label version of Series 17811?

Yes. Laser marking with your logo, custom surface finish, and private-label packaging are available for OEM programs; send the required quantity and specification for a formal quotation.
