Metric Banjo Hydraulic Hose Fitting: 70011 Series (DIN 7642)

Why This Metric Banjo Hydraulic Hose Fitting Passes the Compliance Gate

This 70011 series metric banjo hydraulic hose fitting is the hose-end body of a two-part banjo joint, using a hollow bolt through an eye to enter a port at any rotation angle. Engineers, distributors and repair shops choose it when a port faces a fixed direction and the hose route still has to reach it. The body seals on two washer faces, not on the thread, so it will not crush a port or fight a fixed elbow. Every shipment carries a batch number that traces material, heat treatment and pressure test back to the melt.

Core Advantages

• 360-degree adjustable orientation. The eye can be rotated before final tightening, so the hose route is set after the fitting is seated, not before.
• Double washer-face sealing. One sealing washer above and one below the eye are compressed against the port face for a reliable, re-usable joint surface.
• Carbon steel or 304/316L stainless. Cold-headed for grain flow, carburized and hardened HRC 20-28, then finished in trivalent zinc, zinc-nickel or Dacromet.
• 21 stocked combinations. Eight metric thread sizes from M10X1 to M30X1.5 cover hose bores DN 5 to DN 32 in a single DIN 7642 family.

Technical Specifications

What Is a Banjo Body Hydraulic Hose Fitting?

A banjo body is the hose-side half of a banjo connection. It carries a ring-shaped eye through which a hollow banjo bolt passes; the bolt screws into the port and the eye is clamped between two sealing washers. Because the bolt does not turn the body, the eye angle can be set freely before the final torque is applied. This is why a metric banjo hydraulic hose fitting suits tight engine bays, transmissions and mobile equipment where a fixed elbow would not fit. Banjo threads are straight (parallel) with washer-face sealing, so they must never be mixed with tapered threads or cone-seat ends.

Dimensional Data

Letter references are quoted exactly as dimensioned on the drawing.

Full Dimension Table (Part Number Matrix)

All figures are transcribed from the 70011 series specification drawing. Part numbers read as series-thread-hose dash, so 70011-16-06 is a 70011 body, M16X1.5 bolt thread, DN 10 hose (dash 06).

NOTE: 1. For use with braided hoses. 2. If use with spiral hoses, hose fitting series number is 70012-XX-XX.

Material and Heat Treatment

Working Pressure and Operating Envelope

Rated pressure is set by the mating end standard and the hose grade together, not by the body alone. A banjo end normally carries a lower pressure rating than a straight-thread end of the same port size, because the seal depends on the washers and the hollow bolt. Confirm the working pressure against the data table and the system pressure before specifying. Do not use a banjo body above the pressure of its matching bolt, hose and washer set, and consult our engineers for high-pressure pulsating duty.

Typical service temperature range is -40 °C to +120 °C, fixed by the hose, washer and fluid actually used. Standard parts ship with a 100% factory pressure test; torque and crimp data sheets are supplied with the order.

Selection and Ordering

How to Read the Part Number Matrix

Read the code from left to right: series, then bolt thread, then hose dash. In 70011-22-08, 70011 is the DIN 7642 metric body family, 22 is the M22X1.5 bolt thread, and 08 is the DN 12 hose. The BOLT column tells you which hollow banjo bolt to order, and the DN and DASH columns set the hose to be crimped. Braided hose uses the 70011 code; spiral hose needs the 70012 code with the same thread and dash pattern.

Thread Size and Dash Chart

Matching Banjo Bolts and Sealing Washers

A metric banjo hydraulic hose fitting only works as a set, so order the body, bolt and washers together. The bolt must match the thread in the BOLT column and be long enough for the eye plus both washers. Sealing washers are usually DIN 7603 copper or aluminum rings and are compressed once; replace rather than reuse a deformed washer. Bodies, bolts and washers are sold separately, so choose the correct thread and eye height for the port.

Cross Reference Service

Send us an OEM number, a worn sample or a photo and our team will map it to the closest 70011 body code. We translate legacy part numbers into the series-thread-dash system without switching your thread or seat type. This keeps spare-parts lists clean when you consolidate several old codes into one metric banjo hydraulic hose fitting family.

Packaging and Logistics

Standard packing is 10 pcs per box with a batch label on every carton. Origin is Made in China, brand HENGHUA, and each order ships with its MTR. Mixed sizes can be boxed to your pick list, and private labels, laser marking and custom thread or surface finishes are available on request.

Assembly and Use Guide

Four-Step Crimping Procedure

1. Cut the hose square and clean, keeping the bore free of debris.
2. Mark the insertion depth on the hose as the fitting drawing requires.
3. Lubricate the hose and the fitting shell lightly, then push the hose fully to the mark.
4. Crimp with the correct die, then verify the crimp diameter with a caliper against the data sheet.

Installing the Banjo End

1. Place one sealing washer on the port face and pass the bolt through the eye and the second washer.
2. Hand-start the hollow bolt into the port, keeping the washer centred on the port face.
3. Rotate the eye to the hose route you need, then hold it while you tighten the bolt to the data-sheet torque.
4. Clean and flatten the port face first, and never use thread tape or thread sealant on a banjo thread.

Installation Warnings

• Do not fit a banjo body without washers, with the wrong washer size, or with a reused, flattened washer.
• Never mix a banjo body with tapered thread (BSPT/NPT) or cone-seat (JIC/ORFS) ports or ends.
• Do not over-torque the bolt: too much force deforms the eye and destroys the washer seal.
• Do not mix bodies, bolts and washers from different brands, series or thread systems.
• Always match thread, bolt length and eye height, and replace washers on every re-assembly.

OEM Customization and Quality Traceability

Customization Options

We build metric banjo hydraulic hose fittings to your drawing or sample, including non-standard eye heights, special thread pitches and selected surface finishes. Laser marking and private labels let your own part number appear on the body. Send a drawing or sample and we reply with a quotation within 24 hours.

Quality and Traceability System

Every batch is carburized and hardened to HRC 20-28, pressure tested and thread-gauged before packing. A batch number links each body back to its material, heat treatment and test records, and the MTR travels with the order. BV or SGS inspection can be arranged when your project requires it.

FAQ

How does a banjo body seal? The hollow bolt seats the eye on the port, and one washer above plus one below the eye are compressed against the faces. The seal is on the washer faces, not on the thread, so no thread tape is needed.

Can I adjust the angle after tightening? Set the eye angle before final torque. Once the bolt is torqued, both washers are seated and should not be loosened to rotate the eye again.

Can I reuse the sealing washers? No. Use a new DIN 7603 copper or aluminum washer each time; a deformed or flattened washer will not seal reliably.

Will this metric banjo hydraulic hose fitting fit a BSPT or JIC port? No. Banjo ends use straight metric threads with washer-face sealing and must not be mixed with tapered or cone-seat ends. Use the matching thread system instead.

Do I need thread sealant or tape? No. The washer pair provides the seal, and tape or sealant can block the oil passage or crack the eye.

Do you supply the matching bolt and washers? Yes. Order the matching metric banjo bolt and DIN 7603 washers with the body so thread, length and eye height all match.

Can you make a custom thread or private-label version? Yes. We produce custom threads, eye heights and surface finishes, and apply laser marking or private labels on request.
