JIS Flange Hydraulic Hose Fitting: 88111 Series (Straight)

Why This JIS Flange Hydraulic Hose Fitting Passes the Compliance Gate

The 88111 Series is a straight JIS flange hydraulic hose fitting with a crimp-style barbed hose end and a Japanese-standard (JIS B8363) flange head. It is built for hydraulic lines on Japanese-built excavators, loaders, and construction machinery where flange-port connections are standard practice. For OEMs, the flange head geometry is interchangeable with original Japanese flange hardware, so existing machine drawings stay untouched. For distributors, the series covers the common 5/8 inch flange with three hose bores under one part number family. For maintenance teams, the straight body keeps routing short and compact inside tight chassis areas.

Why this JIS flange hose fitting passes the compliance gate:

• Straight configuration with a compact overall length A from 45 mm
• 5/8 inch flange head: C 34.2 mm outer diameter, L 6.7 mm lip thickness
• Hose bores DN 12, DN 16, and DN 20 (dash 08, 10, 12) on one flange size
• Carbon steel cold-formed body, case hardened, with corrosion-resistant finish options
• 100 percent pressure testing and full batch traceability at the HENGHUA factory
• Braided-hose series; spiral-hose counterparts order as 88112-XX-XX

Core Advantages

1. Interchangeable Japanese flange geometry. The flange head follows the JIS B8363 flange interface, so the fitting mates with existing ports, O-rings, and clamp hardware without rework.
2. Three hose bores on one flange size. Carry DN 12, DN 16, and DN 20 to serve several hose diameters while stocking a single flange pattern.
3. Braided and spiral coverage. The listed numbers serve braided hoses; spiral-hose orders simply move to the 88112 series.
4. Tested and traceable. Every fitting is 100 percent pressure tested and batch-coded, with material certificates available on request.

Technical Specifications

What Is a JIS Flange Hydraulic Hose Fitting?

A JIS flange hydraulic hose fitting combines a Japanese-standard flange head with a crimped hose attachment. The flange head is bolted to a matching flange port with an O-ring seal, while the barbed end is pressed into the hose by a crimping machine.

The 88111 Series is the straight member of the family. It connects a JIS flange port to a braided hydraulic hose in a straight line, which suits pump, valve, and cylinder lines where a compact and low-stress layout is required.

Dimensional Data

Full Dimension Table (Part Number Matrix)

Read each part number from left to right: 88111-10-08 breaks down as 88111 (braided straight JIS flange series), 10 (flange size 5/8 inch in 1/16 inch dash), and 08 (hose dash). All listed sizes share one 5/8 inch flange pattern.

Dimensions are in millimeters.

Note: the part numbers above are for use with braided hoses. If the assembly uses spiral hoses, the hose fitting series number becomes 88112-XX-XX.

Working Pressure and Operating Envelope

• Flange port hardware (O-ring, bolts, clamp halves) is sized to the Japanese flange standard used on the machine.
• Assembly working pressure is governed by the selected hose and the crimped assembly, not by the fitting alone.
• Every fitting passes a 100 percent factory pressure test before packaging.
• Typical service temperature range is -40 °C to +120 °C, with system derating set by the hose and seal compounds.
• A crimp data sheet with verified crimp diameters is provided with every order; always follow the values on that sheet.

Selection and Ordering

How to Read the Part Number Matrix

The matrix lists three braided-hose part numbers for the 88111 JIS flange hydraulic hose fitting. Match the hose dash first, then confirm the flange size. If the project runs spiral hose, keep the same dash pattern and move to series 88112.

Assembly and Use Guide

Four-Step Crimping Procedure

1. Cut the hose square and clean the end; remove loose rubber particles.
2. Mark the insertion depth on the hose as indicated in the crimp data sheet.
3. Lubricate the barb and push the hose to the depth mark without twisting.
4. Crimp with the specified die set, then verify the crimp OD with a caliper against the data sheet value.

Mounting the Flange Connection

Align the flange head squarely with the port face and confirm the O-ring sits cleanly in its groove. Insert the bolts or clamp halves supplied with the mating hardware, then tighten evenly in a diagonal sequence to the torque stated in the data sheet.

Installation Warnings

• Do not mix hoses, fittings, or ferrules from different suppliers in one crimped assembly.
• Do not use a braided-hose fitting on a spiral hose; the part number must move to the 88112 series.
• Bolts and clamp halves are not included; order them separately to the flange standard.
• A crimped assembly cannot be re-crimped; a wrong crimp means a new fitting.
• Always support long hose runs to avoid vibration fatigue at the fitting body.

OEM Customization and Quality Traceability

Customization Options

• Thread, hose end, and body length adjustments for machine-specific layouts
• Surface finish selection: trivalent zinc, zinc-nickel, or Dacromet
• Laser marking of customer logo, part number, and batch code
• 304 / 316L stainless steel material options for corrosive environments

Quality and Traceability System

Each 88111 series fitting follows the HENGHUA flow: incoming material, cold forming, machining, heat treatment, surface treatment, 100 percent inspection, pressure test, marking, and packaging. The batch code traces back to the raw material heat number, heat treatment records, and inspection report. BV or SGS third-party inspection can be arranged on request.

FAQ

Q: What is a JIS flange hydraulic hose fitting? A: It is a hose end with a Japanese-standard flange head on one side and a barbed crimp end on the other. It connects braided hydraulic hose to flange-port equipment used on Japanese-built machinery.

Q: Which standard does the 88111 flange head follow? A: The flange head is machined to the Japanese flange interface (JIS B8363). Confirm the port pattern and O-ring size with your machine drawing before ordering.

Q: What hose sizes does the 88111 series cover? A: Three bores are listed on the 5/8 inch flange: DN 12 (dash 08), DN 16 (dash 10), and DN 20 (dash 12).

Q: Can I use the 88111 series with spiral hose? A: No. The listed numbers are for braided hoses. For spiral hoses, order series 88112-XX-XX with the same dash pattern.

Q: How is the flange joint sealed? A: The port and flange head are sealed with an O-ring. Install the O-ring in its groove, align the faces, and tighten the bolts evenly to the specified torque.

Q: Do I need to buy bolts and clamp halves separately? A: Yes. Bolts, clamp halves, and O-rings belong to the mating flange hardware and are ordered separately to the flange standard.

Q: What documents come with a HENGHUA order? A: Each order can include an MTR, batch traceability records, and the crimp data sheet. BV or SGS third-party inspection is available on request.

Q: How fast is a quotation? A: Quotations are answered within 24 hours. Samples ship worldwide with a full dimensional report.
