The 12611 and 12612 (including 12611A/12612A) straight swaged hose fittings are purpose-built for BSP standard high-pressure fluid systems, featuring a precision-engineered 60° male cone seat that delivers permanent metal-to-metal sealing performance. Manufactured via one-piece closed-die forging with multi-axis CNC machining, these fittings eliminate the internal porosity and structural weaknesses inherent in cast alternatives, ensuring exceptional resistance to sudden pressure spikes and long-term mechanical fatigue. The smooth, burr-free BSP threads provide a seamless, bind-free installation experience, while the precision-machined cone seat forms a self-energizing seal that tightens proportionally with increasing system pressure. Suitable for conveying hydraulic oil, industrial water and compressed gases, these fittings effectively prevent hazardous fluid leaks and pressure drops, drastically reducing unplanned maintenance downtime and enhancing the overall safety and reliability of industrial fluid networks.
Manufactured in strict compliance with international BSP pipe fitting standards, all thread profiles, 60° cone angles and swaging dimensions are controlled to micron-level tolerances. Carbon steel variants pass 120-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 1/8" to 2" to accommodate diverse flow requirements. Complete dimensional drawings, swaging parameters and pressure rating data are available upon request, and all fittings are 100% interchangeable with equivalent BSP 60° cone fittings from global mainstream brands.
Self-Energizing 60° Cone Seal: Precision-machined 60° cone seat forms a tight metal-to-metal seal that strengthens with increasing system pressure, eliminating elastomer degradation risks in high-temperature applications.
Superior Vibration Dampening: The deep cone seating interface creates inherent friction that prevents joint loosening under continuous machinery vibration and pulsating hydraulic flow conditions.
Optimized Internal Flow Path: Smoothly polished internal bore with gradual transition geometry minimizes fluid turbulence and pressure drops, improving overall hydraulic system energy efficiency by up to 7%.
Anti-Galling Precision Threads: Cold-rolled BSP threads deliver a smooth, grit-free engagement, preventing metal galling during high-torque installation and supporting repeated disassembly without damage.
Broad Media Compatibility: Chemically stable material and surface treatments ensure reliable performance with aggressive hydraulic oils, synthetic lubricants, industrial water and compressed gases.
Universal Cross-Standard Compatibility: Strictly adheres to BSP standards while offering seamless integration with DIN, ANSI, GB and JIS system components, simplifying global equipment sourcing.
Carbon Steel (Cr6+-Free Cr3+ Zinc Plated)
Adopts an environmentally responsible trivalent chromium zinc plating process with uniform coating adhesion, providing exceptional rust and oxidation resistance that exceeds 120-hour salt spray test benchmarks. It offers 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.
Heavy Construction Machinery: Standard connection for excavator hydraulic lines, loader steering systems and crane boom cylinders, with excellent resistance to shock loads and outdoor weather exposure.
Agricultural Equipment: Used in high-pressure irrigation systems, combine harvester hydraulic drives and tractor implement connections, withstanding dust, debris and continuous field vibration.
Petrochemical Industry: Suitable for process piping and hydraulic control systems in refineries and chemical plants, with stainless steel variants providing reliable corrosion resistance to aggressive media.
Marine & Shipbuilding: Ideal for ship deck machinery, winch hydraulic systems and offshore platform fluid lines, withstanding salt spray corrosion and harsh marine environmental conditions.
General Industrial Manufacturing: Used in hydraulic power units, machine tool circuits and compressed air systems, ensuring stable and leak-free operation for continuous production processes.
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 BSP threads and the critical 60° cone sealing surface are machined in a single setup on 3-axis CNC lathes, ensuring perfect coaxiality and dimensional consistency across every batch. Each unit undergoes 100% 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 dynamic impulse testing and accelerated salt spray evaluation to guarantee long-term reliability.
We utilize high-grade carbon steel and premium stainless steel. The carbon steel variants feature an eco-friendly Cr3+ zinc plating, while the stainless steel options undergo a thorough passivation process. Both treatments are specifically chosen to maximize corrosion resistance and durability in highly demanding industrial environments.
Yes, while these specific fittings are precision-machined to BSP standards, their intelligent design and our broader product manufacturing capabilities ensure high compatibility with DIN, ANSI, GB, and JIS specifications, facilitating seamless integration into diverse global fluid systems.
Absolutely. We possess robust OEM and ODM manufacturing capabilities. Our experienced engineering team can work directly from your technical drawings, CAD files, or physical samples to develop, test, and manufacture non-standard hydraulic fittings tailored to your precise operational requirements.
We employ a strict, multi-layered packaging strategy to prevent mechanical damage and environmental contamination. Every single fitting is equipped with a dedicated thread protective cap, sealed securely in a moisture-resistant plastic bag, packed tightly into a sturdy blank carton, and finally strapped onto a fumigation-free wooden pallet.
For standard bulk volume orders, our typical production and delivery cycle is approximately 30 days. We also maintain a substantial, ready-to-ship inventory of conventional sizes and standard configurations, allowing us to rapidly fulfill and dispatch smaller trial orders or urgent replacement requests.
Every production batch undergoes rigorous quality control under our certified ISO9001 system. This comprehensive testing protocol includes dynamic impulse pressure testing, highly accurate dimensional projection checks, and metallurgical analysis to ensure the 60-degree cone provides a flawless, metal-to-metal seal capable of withstanding severe hydraulic pressures without failure.
