SAE Flange 9000 PSI Interlock Hydraulic Hose Fitting: 87913 Series

Why This SAE Flange Fitting Passes the Compliance Gate

The HENGHUA 87913 Series is a straight 9000 psi flange fitting for spiral hose circuits that demand heavy-duty pressure performance. A four-bolt SAE flange head in the SAE J518 / ISO 6162 style is joined to an interlock crimp barrel, the construction type engineered for spiral-wound hose. OEM builders get a pressure-capable termination for mining and heavy-equipment lines; distributors carry one part number that defines both flange size and hose dash; maintenance teams can rebuild a flange connection on site with standard tools and a crimp data sheet.

Key points:

• Rated as part of the HENGHUA 9000 psi flange fittings range, built for mining, tunnelling and heavy-equipment hydraulics.
• Straight profile suits direct flange-to-hose routing in the tightest machine envelopes.
• Flange sizes from 3/4 in to 1-1/2 in and hose bores from DN20 to DN40 (dash 12 to 24).
• Interlock crimp construction for spiral hose, with 100% factory pressure testing and full batch traceability.

Core Advantages

1. 9000 psi-class headroom. Designed into the HENGHUA 9000 psi flange fittings family so it survives duty cycles that fatigue ordinary 3000 or 6000 psi flange parts.
2. One part number, no guesswork. The catalog number encodes flange dash and hose dash, so ordering and warehousing stay simple for distributors.
3. Interlock crimp for spiral hose. The clamp-style interlock barrel grips spiral reinforcement without tube crushing, keeping the assembly stable under impulse.
4. Tested, marked and traceable. Every fitting passes 100% pressure testing, batch marking and hardness records before it leaves the HENGHUA factory in China.

Especificaciones técnicas

What Is a 9000 psi Flange Fitting?

A 9000 psi flange fitting is a flange-type hose termination rated for the working-pressure class of heavy spiral hose. Instead of a threaded union, the hose ends in a flange head that bolts to a pump, valve or manifold port using the same four-bolt interface as an SAE J518 / ISO 6162 flange connection.

When you compare 9000 psi flange fittings, check three things: flange head dimensions against your mating half, the hose dash marking on the spiral hose, and the crimp data for your specific hose brand. HENGHUA supplies the crimp data sheet with every order so the assembled joint is verifiable, not assumed.

Dimensional Data

The drawing on the specification sheet labels four dimensions directly. All values are in millimetres.

Full Dimension Table (Part Number Matrix)

Each row is one orderable fitting. Part number format is 87913-flange dash-hose dash, where the flange dash and the hose dash both follow the 1/16 in dash-count system. Read the flange size column first, then the hose bore column, then confirm A, C, D and L against your 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.

Material and Heat Treatment

Working Pressure and Operating Envelope

The 87913 Series sits in the HENGHUA interlock flange fittings range, where every part is a 9000 psi flange fitting matched to a spiral-hose dash size. Because these flange fittings for spiral hose keep one pressure class from flange head to crimp barrel, 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.

Selection and Ordering

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 87913 Series is the straight interlock fitting for these spiral-hose sizes, so one table covers your hose series and flange size in a single search.

How to Read the Part Number Matrix

Read 87913-16-12 from left to right. 87913 is the series, 16 is the flange dash (1 in), and 12 is the hose dash (DN20). 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.

Cross Reference Service

Send the legacy or OEM part number from the fitting you are replacing, together with a photo and the hose dash if possible; this works for older 9000 psi flange fittings from any brand. HENGHUA translates it against the 87913 matrix and confirms the match in writing before you order, so retrofit buying stays low-risk.

Packaging and Logistics

Assembly and Use Guide

Four-Step Crimping Procedure

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 fitting 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.

Mounting the Flange Connection

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 before bolting. Place the O-ring or seal ring in its groove, bring the two flange halves face-to-face, and tighten the cap screws in a diagonal sequence to the torque value in the data sheet. Never tighten one screw fully before the others are seated.

Installation Warnings

• ❌ 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.
• ✔ Use only the crimp data sheet supplied for the hose brand and dash size.
• ✔ Verify the flange size and hose dash before assembly, and torque bolts in a diagonal pattern.

FAQ

1. What pressure rating does the 87913 Series support?

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

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 87913 family. For braided hose, select the braided-hose version of the fitting family and confirm it with HENGHUA.

1. Which flange interface does the head match?

The head follows the four-bolt SAE J518 / ISO 6162 flange style. Match the flange size column to your mating flange half and cap screw size before ordering.

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. What is the difference between interlock and braided-hose flange fittings?

Interlock flange fittings use a clamp-style barrel that suits spiral reinforcement, which makes them the flange fittings for spiral hose in this 9000 psi family. Braided-hose fittings use a different crimp structure, and the two families are not interchangeable on the same hose.

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?
