10611 Metric Male Double-Use 60-Degree Cone Seat Hydraulic Hose Fittings

Metric 60-degree cone hydraulic hose fittings seal two ways from one part number: against a female 60-degree cone seat for metal-to-metal sealing, or against a flat port face with a bonded seal washer. The 10611 double-use series covers 18 part numbers from DN6 (-04) to DN40 (-24), with metric threads from M14x1.5 to M52x2, engineered for wire-braided hydraulic hose. If you build or maintain machines with metric 60-degree cone ports or flat-face ports, this page is your working reference: dimensions, part numbers, seal selection rules and OEM options.

Why Choose These 60-Degree Cone Hose Fittings

• One fitting, two seal methods. The same male end seals in a 60-degree internal cone seat or on a flat face with a bonded seal washer, so one part number covers both port types and you carry less stock.
• 18 sizes from DN6 to DN40. Metric threads from M14x1.5 to M52x2, including fine-pitch D versions, cover small control lines to large return lines.
• No tape, no O-ring to lose. The 60-degree cone gives a metal-to-metal seal; the bonded seal option uses a washer that stays in place on the hex face. Neither method needs thread sealant.
• OEM-ready. Laser marking, custom plating, material test reports and batch traceability for every order, with bonded seal washers supplied to match.

Standards and traceability. Threads are ISO 724 metric threads, standard or fine pitch. The sealing geometry follows the double-use 60-degree cone seat / bonded seal configuration used across the widely adopted Chinese 10-series hose fitting numbering system. Fittings are designed to pair with wire-braided hose built to EN 853 1SN/2SN or SAE 100 R1AT/R2AT performance classes. Dimensional inspection reports and material test certificates are available for OEM gate checks.

Double-Use Explained: 60-Degree Cone Seat or Bonded Seal

“Double use” means the same 10611 fitting body can create a leak-free joint on two different port designs:

• 60-degree cone seat. If the female port has a machined internal 60-degree cone, the cone on the fitting seats metal-to-metal inside it. No washer, no sealant, no O-ring. This is the classic cone-seal joint found on many Chinese-built hydraulic cylinders, pumps and manifolds.
• Bonded seal. If the female port face is flat, place a bonded seal washer (a steel washer with a bonded rubber ring, DIN 7603 style) under the hex head. As the fitting is torqued, the rubber ring compresses against the flat face and seals the joint.

The port determines the method: a cone seat takes the cone seal, a flat face takes the bonded seal. Never use both at once, and never put a bonded seal into a cone seat, because the washer will keep the cone from seating and the joint will leak.

One sentence to remember: the 60-degree cone or the bonded seal does the sealing, and the thread only holds the joint together. That is why you must never wrap PTFE tape on these straight metric threads. Tape belongs on taper threads such as NPT or BSPT.

Which seal method should I use?

60-degree cone vs 24-degree cone (DIN 2353 style)

Both families are metal cone seals, but the cone angle is different. DIN 2353 / ISO 8434-1 style fittings seal on a 24-degree cone; these fittings seal on a 60-degree cone. Even when the metric thread size looks the same, the two cones will not mate. Check the cone angle of your port before ordering, and never force one family into the other.

Metric 60-degree cone vs related cone systems

Fittings that look similar exist under other thread systems: ISO 8434-6 and BS 5200 describe 60-degree cone stud ends on BSP G-threads, and Japanese JIS B 8363 covers 60-degree cone joints with subtle dimensional differences. The 10611 series is the metric-thread double-use configuration common on Chinese and Asian equipment. If your machine is of Japanese or European origin, send us a photo of the port and the old fitting, and we will confirm whether the 10611 series is the correct match before you order.

10611 Series Technical Specifications

Materials and processing

• Body material options: high-strength carbon steel (20#/35#/45# grades, cold-formed or machined) as standard; stainless steel 304 or 316L available for corrosive or wash-down environments.
• Surface treatment: zinc plating as standard; yellow, white or black zinc, zinc-nickel and Dacromet coating available for higher salt-spray requirements.
• Heat treatment: hardness and case depth are controlled per drawing to keep the thread and the cone zone fatigue-resistant; typical surface hardness range HRC 20-28 (confirm the exact code on your drawing or PO).
• Bonded seal washer: supplied as standard with the fitting or on request per order; specify the seal material for your fluid (NBR type for mineral oils as standard).

Full dimension and part number table

All linear dimensions are in millimeters. E = thread, DN = hose bore, A and C = lengths per the supplier drawing, S1 = hex across flats. Part numbers with a D suffix are the fine-pitch version of the same thread size (for example 10611-27-10D is M27x1.5 while 10611-27-10 is M27x2).

Full dimensioned CAD drawings are available on request so your engineers can verify every length and the cone geometry before you commit a batch.

Working pressure: the honest answer engineers need

A crimp hose assembly fails at its weakest link, so the rating of a 10611 fitting depends on the hose you pair it with and the crimp quality. Wire-braided hydraulic hose in this size range typically operates between roughly 80 and 350 bar depending on bore size and construction (1SN or 2SN). Send us your hose specification and we will confirm the working pressure, burst margin and the recommended ferrule for your exact hose brand – the check is free and takes one message. For derating at elevated temperature, follow the hose manufacturer’s pressure-temperature curve, because the rubber cover and tube lose capacity above about +100°C.

Which Fitting Series Do You Need: 10611 (Braided) or 10612 (Spiral)?

The part number changes with the hose construction, because the barb geometry and the crimp parameters are different. This is the first selection check for every order.

When in doubt, check the hose label: braided hose is marked 1SN, 2SN or R1AT, R2AT; spiral hose is marked 4SP, 4SH or similar. Ordering the wrong series means the ferrule will not crimp correctly, so confirm the hose construction before you buy.

Part Number Decoder and How to Order

The 10611 part number carries the whole specification, so purchasing can copy it straight into a PO without another round of emails:

10611 – 22 – 08

• 10611 = double-use 60-degree cone seat / bonded seal series for braided hose
• 22 = thread nominal size (here M22x1.5)
• 08 = hose dash size (here DN12, 1/2-inch class bore)
• D suffix = fine-pitch thread version (for example 10611-27-10D uses M27x1.5)

Because one thread size can serve several hose bores, always quote both the thread size and the dash size. If you are replacing an existing fitting, send us a photo of the thread end, the port face and the hose side, plus the hex size, and we will confirm the matching part number the same day. This service is the fastest way to convert an unreadable old part number into a confirmed 10611 order number, and it also tells you whether your port is a cone seat or a flat face.

Bonded seal washers are available as spares or pre-fitted with the fitting. If your maintenance team loses a washer, you replace the washer – never the fitting – which keeps downtime and spares cost low.

Assembly Guide: Four Steps to a Reliable Crimp

These fittings are crimp-style hose ends: the barbed tail is pushed into the hose and a matching ferrule is crimped over the cover. Follow the four steps below on every assembly.

Step 1 – Cut the hose square. Use a sharp hose cutter or cutoff saw. A square, clean cut lets the ferrule grip the cover evenly. A beveled or ragged cut is the most common cause of pull-out failures.

Step 2 – Prepare the insert depth. Push the fitting tail into the hose until it bottoms firmly against the internal shoulder. The hose end must sit at the full insertion depth, not short, or the crimp zone will be wrong.

Step 3 – Lubricate and insert. Apply a thin film of assembly lubricant to the hose bore and the barb. Push the fitting in with a steady twisting motion until it bottoms out, then wipe away excess lubricant. Do not use grease on the cone face or the bonded seal washer.

Step 4 – Crimp and verify. Crimp the matched ferrule with the hose manufacturer’s crimp specification. After crimping, always measure the crimp outside diameter with a caliper and compare it with the crimp table. The measured value must sit inside the allowed tolerance band. If it is out of tolerance, do not put the assembly into service – cut it off and re-crimp with a corrected setting.

Warnings: three mistakes that cause leaks and blow-outs

• Never mix hoses, fittings and ferrules from different manufacturers. Even when the dash size matches, crimp parameters and barb geometry differ, and a mismatched set can leak or pull apart under pressure.
• Never use a bonded seal in a 60-degree cone seat, and never stack a cone seal with a bonded seal on the same joint. Each port design takes exactly one sealing method. Double sealing prevents the cone from seating and guarantees a leak.
• Never put PTFE tape or sealant on the straight metric thread, and never force a 24-degree cone fitting or a flat-face O-ring fitting onto a 60-degree cone port because the threads happen to fit. The seal face will not mate, and the joint will leak or damage the port.

Aplicaciones típicas

Metric 60-degree cone ports and flat-face bonded-seal ports are specified across a wide range of hydraulic equipment, especially machines built to Chinese or Asian standards and their global service networks:

• Hydraulic cylinders, power units, presses and machine tools
• Plastic injection and die-casting machinery
• Mining, tunneling and construction equipment
• Agricultural and forestry machinery
• Material handling and mobile equipment
• Marine and offshore auxiliary systems

Wherever the port carries a machined 60-degree internal cone or a flat face, the 10611 series is the direct hose connection for braided hose circuits – with one part number serving both.

FAQ

Q: What is a double-use 60-degree cone hydraulic hose fitting? A: It is a crimp-style hose fitting with a metric male thread that seals two ways: metal-to-metal against a female 60-degree cone seat, or against a flat port face using a bonded seal washer under the hex. One part number covers both port types.

Q: Should I use the cone seal or the bonded seal? A: Read the port. A port with a machined internal 60-degree cone takes the cone seal with no washer. A flat-face port takes the bonded seal washer. Never use both on one joint, and never put a washer into a cone seat.

Q: What is the difference between 10611 and 10612 series? A: 10611 is for wire-braided hose (1SN/2SN or R1AT/R2AT) and 10612 is for spiral hose (4SP/4SH style). The thread range is the same, but the barb geometry and crimp parameters differ.

Q: What does the D suffix in the part number mean? A: The D suffix marks the fine-pitch version of the same nominal thread. For example 10611-27-10D is M27x1.5 while 10611-27-10 is M27x2. Order the pitch that matches your port.

Q: Do I need thread tape or sealant on the male thread? A: No. The 60-degree cone or the bonded seal does the sealing. Tape on a straight metric thread is useless and can contaminate the system. Use tape only on taper threads.

Q: Is this fitting the same as a 24-degree cone or ORFS fitting? A: No. DIN 2353 style fittings seal on a 24-degree cone, and SAE ORFS uses inch threads with an O-ring. This series seals on a 60-degree cone or a bonded seal with metric threads. The families are not interchangeable.

Q: Is this the same as ISO 8434-6 or JIS 60-degree cone fittings? A: Related but different thread systems. ISO 8434-6 / BS 5200 60-degree cone stud ends use BSP G-threads, and Japanese JIS B 8363 has subtle dimensional differences. The 10611 series is the metric-thread configuration common on Chinese and Asian equipment. Send a photo of your port and we will confirm the match before you order.

Q: What is the working pressure of these fittings? A: The assembly rating depends on the hose, the ferrule and the crimp quality. Send your hose specification and we will confirm the working pressure and the recommended ferrule for your combination.

Q: Can you make custom part numbers with my logo? A: Yes. We offer laser marking, custom plating, stainless versions and special dimensions, with MTR and batch traceability for OEM programs.
