The 22611 (for braided hoses) and 22612 (for spiral hoses) BSP female 60° cone hose fittings are purpose-built to address the common failure points of female threaded connections in high-pressure fluid systems. Unlike poorly machined female fittings that suffer from cross-threading, misalignment leaks and thread stripping, these components feature precision internal BSP threads machined in a single setup to ensure perfect concentricity with the 60° cone seat. Manufactured via one-piece closed-die forging with multi-axis CNC machining, they eliminate internal porosity and structural weaknesses inherent in cast alternatives, delivering exceptional resistance to hydraulic hammering and continuous mechanical vibration. The self-centering 60° cone interface forms a tight metal-to-metal seal that requires no elastomers, making it ideal for high-temperature applications where rubber seals degrade. Suitable for conveying hydraulic oil, industrial water and compressed gases, these fittings drastically reduce unplanned maintenance downtime and provide a reliable, long-lasting connection for critical industrial fluid infrastructure.
Manufactured in strict compliance with DIN, ANSI, GB, JIS and BSW international standards, all internal thread pitches and 60° cone angle tolerances are controlled to ±0.05mm. Carbon steel variants pass 96-hour neutral salt spray testing without red rust, while stainless steel versions withstand over 500 hours of salt spray exposure. The full size range covers G1/8" to G2" to accommodate both delicate pilot lines and high-volume main fluid arteries. Complete dimensional drawings, swaging parameters and torque specification tables are available upon request, and all fittings are 100% interchangeable with equivalent BSP 60° cone fittings from global mainstream brands.
Precision Internal Thread Geometry: Cold-rolled BSP female threads are burr-free and perfectly pitched, eliminating cross-threading and galling during installation, and supporting repeated disassembly without thread damage.
Self-Centering 60° Cone Interface: The internal cone seat automatically aligns with mating male components during tightening, preventing misalignment-induced leaks that plague poorly machined female fittings.
Multiple Head Configuration: Offers standard hexagon for general use, double hexagon for high-torque heavy-duty applications, and compact round head for tight spaces with limited wrench access.
Void-Free Forged Construction: One-piece closed-die forging eliminates internal porosity and hidden weak points, delivering 2-3x higher burst strength than cast alternatives to withstand extreme pressure spikes.
Vibration-Locking Seal: The tapered 60° cone creates inherent friction that prevents joint loosening under continuous machinery vibration and pulsating hydraulic flow conditions.
Elastomer-Free Sealing: Metal-to-metal cone seal eliminates O-ring degradation risks, making it suitable for high-temperature, high-vacuum and chemically aggressive applications.
Carbon Steel (Cr3+ Zinc Plated, Yellow/White Finish)
Adopts RoHS-compliant trivalent chromium zinc plating available in both bright white and traditional yellow finishes, with uniform coating adhesion that resists chipping and flaking during high-torque wrenching. It provides excellent rust and oxidation resistance, with high tensile strength and outstanding cost-effectiveness, making it ideal for general construction, agricultural machinery and indoor industrial hydraulic systems.
Stainless Steel (Chemical Passivation)
Uses high-quality 304/316L stainless steel billets processed through rigorous low-temperature passivation treatment, which removes surface free iron and forms a dense, self-healing chromium oxide film. This enhances acid, alkali and salt spray corrosion resistance by 300% compared to untreated steel, perfectly suited for marine engineering, offshore oil & gas and chemical processing applications.
Hydraulic Manifold & Valve Block Connections: Ideal for female port connections on hydraulic power units, valve manifolds and control blocks, where precise alignment and leak-free performance are critical.
Agricultural Heavy Machinery: Used in tractor hydraulic systems, combine harvester drives and implement connections, withstanding dust, debris and continuous field vibration.
Mining & Underground Equipment: Suitable for high-pressure hydraulic lines on underground drills, crushers and conveyors, with forged construction resisting impact loads and harsh subterranean conditions.
Oil & Gas Field Operations: Deployed in wellhead control systems and hydraulic power units, with elastomer-free sealing performing reliably in high-temperature and hydrocarbon-exposed environments.
Marine & Shipbuilding: Stainless steel variants for ship deck machinery, winch systems and offshore platform fluid lines, providing long-term corrosion resistance in salt spray and humid marine atmospheres.
The fitting body is formed in a single operation via 1000-ton hot closed-die forging, which aligns the metal grain flow along the load path to maximize tensile strength and fatigue resistance. All internal BSP threads and the critical 60° cone seat are machined in a single setup on 3-axis CNC lathes, ensuring perfect concentricity and eliminating alignment errors between the thread and sealing surface. Each unit undergoes 100% internal and external thread go/no-go gauge inspection, hydrostatic pressure testing at 1.5 times the rated working pressure, and surface finish inspection. Finished products also undergo random batch salt spray testing to guarantee long-term corrosion resistance.
To assist you in making informed, confident procurement decisions, we have compiled detailed answers to the most common technical and operational inquiries regarding our hydraulic fitting solutions.
We are a highly specialized, direct manufacturing facility located in Ningbo, Zhejiang Province, China. We possess our own advanced forging presses, CNC machining centers, and inspection labs, allowing us to maintain absolute, end-to-end control over the production of hose connectors, instrument fittings, and transition joints.
For standard bulk orders, our typical manufacturing lead time is approximately 30 days from order confirmation. However, conventional standard items are frequently kept in stock, enabling immediate dispatch for smaller batch requirements. Highly customized components or orders with multiple complex parts will require a tailored production schedule.
Yes, comprehensive OEM and ODM services are a core pillar of our business. With rich experience in hydraulic design, we can manufacture fittings to your exact proprietary specifications. Furthermore, we offer precision laser marking to engrave your company logo, specific part numbers, or safety ratings directly onto the metal surface.
We strive to offer maximum inventory flexibility to our partners. For any standard fittings currently held in our stock, there is absolutely no MOQ limit. You can order exactly what your current project requires. For non-stock items or bespoke customized products, a reasonable MOQ will be established based on the initial manufacturing setup costs. Please contact our team for specific details.
Our standard and most efficient payment term for international transactions is T/T (Telegraphic Transfer). This ensures secure, transparent, and rapid processing, allowing us to initiate production or dispatch your goods without unnecessary delays.
