BSP Banjo Hydraulic Hose Fitting: 72011 Series Banjo Body (ISO 228 G Thread)

Why This BSP Banjo Hydraulic Hose Fitting Passes the Compliance Gate

The BSP banjo hydraulic hose fitting in the 72011 series is a banjo body with a parallel G-thread (ISO 228) port end and a hose end for crimping. It is built for OEMs, distributors, and repair shops that need a leak-free, angle-adjustable connection on BSPP ports. Each body is machined from cold-forged carbon steel or 304/316L stainless steel, then zinc-plated or Dacromet-coated for corrosion resistance. Because the port end is a straight G thread sealed by two washers, this BSP banjo hydraulic hose fitting installs without the torque guesswork of a tapered thread. Every batch ships with full material traceability plus 100% pressure and thread inspection.

主な強み

• 360° adjustable orientation. The eye can be rotated to any position before final tightening, so the hose can be routed cleanly through tight or obstructed spaces.
• Double-washer face seal. One sealing washer above and one below the eye are compressed against the port face and bolt head, giving a reliable two-sided seal on a parallel G thread.
• Material and surface options. 20#/35#/45# cold-forged carbon steel or 304/316L stainless steel, with trivalent zinc, zinc-nickel, or Dacromet finishes.
• Verified thread and pressure. 100% factory pressure testing and thread inspection, with torque and crimp data sheets supplied per order.

技術仕様

What Is a Banjo Body Hydraulic Hose Fitting?

A banjo body hydraulic hose fitting uses a ring-shaped “eye” at the port end that a hollow banjo bolt passes through. Two sealing washers, one above and one below the eye, are compressed against the port face and the bolt head when the bolt is tightened, creating a double face seal. The hose end is then crimped to the hose, and because the eye can rotate before final tightening, the outlet can be aimed anywhere through 360°.

Unlike a tapered-thread end (BSPT/NPT) or a cone-seat end (JIC/ORFS/24°), a banjo joint seals on flat washer faces, not on a tapered thread or a metal cone. This is why a BSP banjo hydraulic hose fitting must never be sealed with PTFE tape or thread sealant, and must never be mixed with tapered-thread or cone-seat ends. The bolt and body must be matched on thread size, bolt length, and oil-hole position; parts from different series are not interchangeable.

Also note: at the same nominal size, the pressure rating of a banjo end is typically lower than that of an equivalent straight-thread end, because the seal depends on the washers and the hollow bolt body. Always confirm against the data sheet and the actual system pressure, and consult an engineer for high-pressure or pulsating duty.

寸法データ

The drawing labels its dimension columns A, d, D, and H. The table below records the meaning of each symbol as dimensioned on the drawing; the drawing provides no separate letter legend, so values are read directly from the columns.

全寸法表（部品番号マトリックス）

All dimensions are in millimeters unless stated. The port thread is a parallel G thread per ISO 228 (for example G1/4″X19). The coding rule is 72011 - port thread - hose dash: the middle pair follows the port thread size and the final pair follows the hose dash size. Read across each row to match one body to its thread and hose bore, and use the dash number to pick the matching hose size.

Version note (translated from the drawing): NOTE: 1. For use with braided hoses. 2. If used with spiral hoses, the hose fitting series number changes to 72012-XX-XX. The series number printed on the drawing is 72011.

材料および熱処理

使用圧力および動作範囲

The working pressure of a banjo body is set by the port-end standard and the hose rating together; it is not a fixed number for the fitting alone. A typical working temperature range is -40 °C to +120 °C, and the exact value depends on the hose and the seal materials used. Torque and crimp data tables are supplied with each order, and 100% of units are pressure tested before packing. For high-pressure, high-pulse, or safety-critical circuits, always confirm the rating against the data sheet and consult an engineer for the correct selection.

選定と発注

部品番号マトリックスの読み方

Every part number for this BSP banjo hydraulic hose fitting follows the pattern 72011 - port thread - hose dash. The first four digits identify the family and the parallel G-thread port end; the next pair is the port thread code; the final pair is the hose dash size. To order, choose the port thread that matches your BSPP port, then choose the dash that matches your hose bore. Order the banjo bolt and the sealing washers separately, since the body alone does not form a seal.

Matching Banjo Bolts and Sealing Washers

A banjo joint has three parts: the body, the hollow banjo bolt, and two sealing washers. Match the bolt thread to this body’s port thread, and match the bolt length and oil-hole position to the body’s eye depth and port depth. Use one sealing washer above and one below the eye; the common choice is a DIN 7603 copper or aluminum ring, but always confirm the ring material and size against the port face and fluid. The bolt and the washers are ordered separately from the body, so please specify all three when raising an inquiry.

相互参照サービス

If you are replacing an existing part and only have an OEM or legacy number, send it to us and we will translate it to the closest 72011 body and its matching bolt. We compare thread size, hose dash, and eye dimensions to confirm fit before quoting. This helps distributors and repair shops consolidate several old numbers into one reliable family.

包装・物流

Each BSP banjo hydraulic hose fitting is packed 10 pcs per box, with a batch label on each carton that records the series, part number, and batch code. Origin is marked Made in China – HENGHUA. Material test reports travel with the shipment, and third-party inspection (BV / SGS) can be arranged on request. We quote within 24 hours and support OEM and private-label programs.

組み立て・使用ガイド

4段階の圧着手順

1. Cut the hose vertically with a hose cutter so the end is square and free of burrs.
2. Mark the insertion depth on the hose jacket using the crimp data sheet.
3. Apply a thin film of compatible grease and insert the fitting until the mark is reached.
4. Crimp to the specified diameter and verify the crimped outside diameter with a caliper.

Installing the Banjo End

Place one sealing washer above and one below the eye, then pass the hollow banjo bolt through the eye and thread it into the port by hand until it seats. Rotate the eye to aim the hose in the required direction, then tighten to the torque in the data sheet. Keep the port face clean and flat, and use fresh washers each time; a deformed or reused washer is a common cause of leaks. Never use PTFE tape or thread sealant, because the joint seals on the washer faces, not on the thread.

インストールに関する注意事項

• ❌ Missing sealing washers, wrong washer size, or reused and deformed washers.
• ❌ Mixing a banjo end with tapered-thread or cone-seat ends (BSPT/NPT, JIC/ORFS/24°).
• ❌ Over-torquing, which can deform the eye and damage the seal faces.
• ❌ Mixing parts from different brands or different series on the same joint.
• ✔ Correct practice: matched body, bolt, and washers; clean flat port face; correct torque; one washer above and one below the eye.

よくある質問

How does a banjo body seal? It seals on two flat washer faces. One washer sits above the eye and one below, and the hollow bolt compresses them against the port face and the bolt head when tightened.

Can I adjust the hose angle after tightening? Yes, up to the point of final torque. Rotate the eye to the required direction, then tighten to the data-sheet torque, which locks the orientation.

Can the sealing washers be reused? No. Washers deform to match the seal faces, so we recommend new washers for every reinstallation to avoid leaks.

Will this fit a BSPT, NPT, or JIC port? No. This is a parallel G-thread banjo joint and must not be mixed with tapered-thread or cone-seat ends. Match it only to a BSPP port with the correct bolt and washers.

Do I need thread sealant or tape? No. The joint seals on the washer faces, so PTFE tape and thread sealant are not used and can interfere with the seal.

Can you supply matched bolts and washers? Yes. We supply the banjo bolt and DIN 7603 copper or aluminum washers as separate line items, matched to the body you order.

Do you offer bulk and custom orders? Yes. We support wholesale volumes and OEM/private-label customization with laser marking and custom finishes.
