45 Degree Elbow JIS Flange Hydraulic Hose Fitting: 88141 Series

Why This 45 Degree Elbow JIS Flange Hydraulic Hose Fitting Passes the Compliance Gate

The 88141 Series is a 45 degree elbow JIS flange hydraulic hose fitting with a Japanese-standard (JIS B8363) flange head and a crimp-style barbed hose end. It is engineered for hydraulic lines on Japanese-built excavators, loaders, and construction machinery where a flange-port connection must change direction gently. For OEMs, the flange head geometry is interchangeable with original Japanese flange hardware, so machine drawings stay unchanged. For distributors, the series covers the common 5/8 inch flange with three hose bores in one part number family. For maintenance teams, the 45 degree routing reduces hose bending stress and keeps assemblies within narrow clearances.

Why this 45 degree JIS flange fitting passes the compliance gate:

• 45 degree elbow body with a compact flange-to-barb layout
• 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
• Overall height H from 24 mm up to 28.8 mm across the listed sizes
• Carbon steel cold-formed body, case hardened, with corrosion-resistant finish options
• Braided-hose series; spiral-hose counterparts order as 88142-XX-XX

Principais vantagens

1. Space-saving 45 degree routing. The elbow turns the hose gradually, which trims hose length, cuts bending stress, and fits low-profile layouts.
2. Interchangeable Japanese flange geometry. The flange head follows the JIS B8363 flange interface and mates with existing ports, O-rings, and clamp hardware.
3. Three hose bores on one flange size. Stock DN 12, DN 16, and DN 20 while carrying a single 5/8 inch flange pattern.
4. Braided and spiral coverage. The listed numbers serve braided hoses; spiral-hose orders simply move to the 88142 series.

Especificações Técnicas

What Is a 45 Degree Elbow JIS Flange Hydraulic Hose Fitting?

A 45 degree elbow JIS flange hydraulic hose fitting redirects the hose path by 45 degrees at the flange port while keeping the sealing performance of the flange joint. The flange head is bolted to the port with an O-ring seal, and the barbed end is crimped onto the hose.

The 88141 Series suits pump and valve lines where the hose must leave the port at a controlled angle. Because the bend is formed in the fitting body rather than in the hose, the hose keeps a larger natural bend radius and lasts longer in service.

Dados dimensionais

Tabela completa de dimensões (matriz de referências)

Read each part number from left to right: 88141-10-08 breaks down as 88141 (braided 45 degree elbow 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 88142-XX-XX.

Material e tratamento térmico

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.

How to Read the Part Number Matrix

The matrix lists three braided-hose part numbers for the 88141 45 degree elbow 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 88142.

Guia de Montagem e Utilização

Procedimento de crimpagem em quatro etapas

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. Orient the elbow before final torque so the hose points in the planned direction.

Avisos relativos à instalação

• 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 88142 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.
• Check the elbow orientation before tightening; rotating the body after torque can break the seal.

Personalização OEM e rastreabilidade da qualidade

Opções de personalização

• Body length and angle 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

Sistema de Qualidade e Rastreabilidade

Each 88141 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.

Perguntas Frequentes

Q: What is a 45 degree elbow JIS flange hydraulic hose fitting? A: It is a hose end with a Japanese-standard flange head and a barbed crimp end set at a 45 degree angle. It connects braided hydraulic hose to flange-port equipment while turning the line by 45 degrees.

Q: Which standard does the 88141 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 88141 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 88141 series with spiral hose? A: No. The listed numbers are for braided hoses. For spiral hoses, order series 88142-XX-XX with the same dash pattern.

Q: Why choose a 45 degree elbow instead of a straight fitting? A: The elbow turns the hose at the port, so the hose keeps a larger bend radius. This reduces stress and lets the assembly fit tighter layouts.

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