Why This 45 Degree SAE Flange Fitting Passes the Compliance Gate

The HENGHUA 87943 Series is a 45 degree elbow 9000 psi flange fitting for spiral hose circuits in mining and heavy-equipment hydraulics. It routes the hose through a compact 45 degree bend while keeping a four-bolt SAE flange head at the component port, and it carries the ISO 12151-3 and SAE J516 designations printed on the series specification sheet. OEM builders use it to clear obstacles without extra hose length; distributors stock one number that fixes flange size and hose dash; maintenance teams shorten rework because the bend angle and drop dimension are factory-controlled.

Key points:

• A true 9000 psi flange fitting family built for spiral-wound hose and impulse-heavy duty cycles.
• 45 degree elbow geometry with a defined H drop, so hose routing stays predictable in tight machine bays.
• Flange sizes from 3/4 in to 1-1/2 in and hose bores from DN20 to DN40 (dash 12 to 24).
• Interlock crimp barrel, 100% factory pressure testing, batch marking and crimp data sheet with every order.

主な強み

1. Space-saving elbow. The 45 degree outlet turns the hose toward the routing path while the flange head stays bolted at the port, which is the reason most OEMs spec a 45 degree flange fitting over a straight one in confined bays.
2. 9000 psi-class integrity. This part is designed into the HENGHUA 9000 psi flange fittings range, so the bend, the flange head and the crimp barrel share one pressure philosophy for spiral hose.
3. Predictable envelope. The A and H dimensions are printed per size, which lets pipework designers clear obstacles before a single hose is cut.
4. Tested and traceable. 100% pressure testing, batch hardness records and full traceability apply to every 87943 elbow leaving the HENGHUA factory in China.

技術仕様

What Is a 45 Degree 9000 psi Flange Fitting?

A 45 degree flange fitting is a flange-type hose termination whose outlet is angled 45 degrees from the flange axis. It is used where the hose must leave the port at an angle, avoiding tight bends that shorten spiral hose life. On the 87943 Series the flange head follows the four-bolt SAE J518 / ISO 6162 style and the part is marked to ISO 12151-3 and SAE J516 as printed on the sheet.

When you evaluate 9000 psi flange fittings in elbow form, compare the A length and the H drop against your routing space, then confirm the hose dash. HENGHUA publishes both dimensions for every size and supplies the crimp data sheet with the order, so the installed envelope is known before you buy.

寸法データ

The drawing on the specification sheet labels A, C, H and L directly. D appears in the dimension table and matches the shoulder-neck diameter used across the 87913 family drawing. All values are in millimetres.

全寸法表（部品番号マトリックス）

Each row is one orderable fitting. Part number format is 87943-flange dash-hose dash, where both dashes follow the 1/16 in dash-count system. Read the flange size and the hose bore first, then confirm A, C, D, H and L against your routing envelope.

This sheet covers the interlock (spiral-hose) version of the series only. If your hose is braided rather than spiral, confirm the correct fitting type with HENGHUA before ordering, because braided and spiral hose fittings are not interchangeable.

材料および熱処理

使用圧力および動作範囲

The 87943 Series belongs to the interlock flange fittings range where every part is a 9000 psi flange fitting matched to a spiral-hose dash size. These flange fittings for spiral hose hold one pressure class from flange head to crimp barrel, and the service envelope of each crimped assembly is confirmed against the hose rating in the supplied data sheet. Treat them as high pressure flange fittings first: size the flange, size the hose, then confirm the crimp.

選定と発注

Hose Series and Dash Selection

Start from the hose on the machine. Read the dash number printed on the spiral hose and match it to the hose dash column in the matrix: dash 12 (DN20), dash 16 (DN25), dash 20 (DN32) or dash 24 (DN40). The 87943 Series is the 45 degree interlock fitting for these spiral-hose sizes, so the elbow angle, the hose series and the flange size are resolved in one table lookup.

部品番号マトリックスの読み方

Read 87943-20-20 from left to right. 87943 is the series, 20 is the flange dash (1-1/4 in), and the second 20 is the hose dash (DN32). The flange dash equals the flange size in 1/16 in units, so 12, 16, 20 and 24 correspond to 3/4 in, 1 in, 1-1/4 in and 1-1/2 in flanges.

Send the legacy or OEM part number from the elbow you are replacing, plus a photo and the hose dash if available; this works for older 9000 psi flange fittings from any brand. HENGHUA translates it against the 87943 matrix and confirms the match in writing, so retrofit buying stays low-risk.

組み立て・使用ガイド

4段階の圧着手順

Every interlock flange fitting for spiral hose follows the same controlled crimp sequence.

1. Cut the spiral hose square with a sharp abrasive saw; no angled or frayed ends.
2. Mark the insertion depth on the hose with the depth value from the crimp data sheet.
3. Lubricate the hose end and push the elbow stem fully to the depth mark.
4. Crimp with the interlock die set and verify the crimp outside diameter with a vernier caliper against the data sheet value.

フランジ接続部の取り付け

Mounting a high pressure flange fitting takes minutes when the halves match. Check that the flange head and the mating flange half share the same flange size, then orient the elbow to its routing angle before the bolts are torqued. Place the O-ring or seal ring in its groove, bring the two halves face-to-face, and tighten the cap screws in a diagonal sequence to the torque value in the data sheet.

インストールに関する注意事項

• ❌ Do not mix hose, fitting or ferrule brands in one crimped assembly.
• ❌ Do not use a braided-hose fitting on spiral hose, or a spiral-hose interlock fitting on braided hose.
• ❌ Do not reuse a crimped fitting or re-crimp after removal.
• ❌ Flange halves and cap screws are not included and must be ordered separately to the correct size.
• ✔ Align the 45 degree outlet before final torque so the hose does not twist after assembly.
• ✔ Use only the crimp data sheet supplied for the hose brand and dash size.

よくある質問

1. What pressure rating does the 87943 Series support?

The series is catalogued at the 9000 psi level as a 9000 psi flange fitting for spiral hose in 45 degree form. The final assembly working pressure is set by the hose rating and the crimp specification in the data sheet supplied with the order.

1. Why choose a 45 degree elbow flange fitting instead of a straight one?

The 45 degree outlet lets the hose leave the port at an angle, which clears structural obstacles and avoids bend radii that shorten spiral hose life. The H drop dimension on the sheet makes the routing envelope predictable. Like all flange fittings for spiral hose in the 9000 psi family, this interlock flange fitting keeps its pressure class through the crimp.

1. Which flange interface does the head match?

The head follows the four-bolt SAE J518 / ISO 6162 flange style, and the series sheet prints the ISO 12151-3 and SAE J516 designations. Match the flange size column to your mating flange half and cap screw size.

1. How do I identify the correct part number from an old fitting?

Measure the flange size and read the dash marking on the hose, then look them up in the matrix. Alternatively use the cross reference service and send the legacy part number.

1. Is this fitting only for spiral hose?

Yes. The interlock crimp barrel is designed for spiral-wound hose, and this part is one of the flange fittings for spiral hose in the 87943 family. For braided hose, select the braided-hose version of the fitting family.

1. Which surface treatments are available?

Trivalent zinc, zinc-nickel and Dacromet are standard options, plus 304/316L stainless steel. Tell HENGHUA the environment and expected salt-spray exposure.

1. Can HENGHUA add private marking?

Yes. Laser marking of your logo, part number and batch code is available, and private-label packing can be arranged.

1. What documents come with the fittings?

A crimp data sheet ships with every order of high pressure flange fittings, and MTR, batch traceability records and third-party inspection reports are available on request.
