The 2J / 6504 MJ-FJS straight swivel adapter is professionally engineered for high-pressure hydraulic pipeline systems, adopting 37° JIC male flare to 37° JIC female swivel configuration. Manufactured in strict accordance with SAE J514 international standards, it features integral forging and CNC precision machining, with a 37° flare seating mechanism to form a tight metal-to-metal seal. The independent rotating female end eliminates hose twisting and torsional stress during installation, effectively resisting mechanical vibration, thermal expansion and extreme pressure spikes. Suitable for stable transmission of hydraulic oil, industrial water and compressed gas, it reduces hose premature failure, lowers maintenance costs, and ensures long-term leak-free operation of heavy-duty industrial fluid systems.
Manufactured in full compliance with SAE J514 international industry standards, all thread dimensions, 37° flare angle and tolerances are strictly controlled. The product passes 96-hour neutral salt spray test with reliable corrosion resistance, with a full size range from 1/4" to 2-1/2". Complete dimensional drawings, thread parameters and pressure rating data can be provided according to customer requirements, 100% interchangeable with mainstream international brand standard parts.
Anti-Torsion Swivel Design: Independent rotating female nut eliminates hose twisting during assembly, reduces mechanical stress and premature hose failure, extends the service life of the entire pipeline system.
Reliable 37° Flare Sealing: Precision machined 37° cone seating forms a tight metal-to-metal seal, effectively absorbs equipment vibration, maintains leak-free performance under long-term high-pressure and dynamic load conditions.
Full Size & Universal Interchangeability: Complete size range from 1/4" to 2-1/2", strictly compliant with SAE J514 standard, 100% interchangeable with mainstream brand parts, no compatibility risks for equipment maintenance.
Wide Media Adaptability: Chemically stable material and structure are compatible with hydraulic oil, industrial water, compressed gas and other common industrial media, a versatile choice for inventory management.
Quick & Easy Installation: Standardized JIC thread profile ensures smooth wrench-tight assembly, no need for sealants or welding, greatly reduces on-site installation labor time and difficulty.
Carbon Steel (Cr3+ Zinc Plated)
Adopts eco-friendly trivalent chromium zinc plating process, with excellent rust and oxidation resistance, high tensile strength and pressure tolerance, cost-effective for conventional hydraulic systems, construction machinery and general industrial working conditions.
Stainless Steel (Passivation)
Through rigorous professional passivation treatment, it forms a dense protective oxide layer, with outstanding chemical corrosion resistance and hygiene performance, perfectly suitable for marine, petrochemical, food processing and other highly corrosive or high-cleanliness working environments.
This JIC male to female swivel adapter is widely used in high-pressure hydraulic pipeline connection scenarios in various core industrial fields:
Construction & Earthmoving Machinery: Hydraulic pipeline connection for excavators, bulldozers, loaders and other mobile heavy equipment, adapting to high-vibration field working conditions.
Industrial Manufacturing: Pipeline assembly for automated production lines, hydraulic stations, industrial cleaning high-pressure water systems, machine tools and compressed air systems.
Agricultural Machinery: Hydraulic system piping for high-horsepower tractors, combine harvesters and other agricultural equipment, resistant to outdoor harsh weather and complex working conditions.
Petrochemical & Marine Engineering: Medium transmission pipelines for oil and gas, chemical processing systems, ship equipment and offshore platforms, with corrosion-resistant material options for harsh environments.
The adapter body is formed by high-tonnage integral hot forging to optimize metal grain structure, ensuring dense internal matrix and excellent burst pressure resistance. The 37° flare sealing surface and JIC threads are processed by multi-axis CNC machine tools with micron-level precision. Each batch undergoes strict thread gauge inspection, dimensional verification and pressure sealing test before delivery, fully complying with SAE J514 standard requirements, ensuring stable and reliable long-term operation under extreme high pressure.
Frequently Asked Questions (FAQ)
A: Yes, we are a specialized manufacturer based in Ningbo, Zhejiang Province, China. Our facility is entirely dedicated to the precision engineering and production of hydraulic hose connectors, instrument fitting connectors, transition joints, and related fluid power accessories.
A: We highly encourage quality verification. We welcome sample orders so you can physically test the thread precision, material finish, and sealing capabilities. We can send samples with a very reasonable charge, with the shipping freight handled on your account. Mixed sample batches are also fully acceptable.
A: For standard bulk orders, our production and delivery cycle is approximately 30 days. However, because we maintain a substantial inventory of conventional products, we can often process and dispatch small-batch shipments almost immediately. Custom products or orders with highly complex multiple parts will require a tailored timeline.
A: Our MOQ policy is designed to be highly flexible. If the specific 6504 MJ-FJS / 2J sizes you require are currently in stock, there is absolutely no MOQ limit. We will only establish an MOQ for products that are temporarily out of stock or require custom manufacturing. Please contact our team with your specific requirements for exact details.
A: Absolutely. We have extensive experience as an OEM/ODM provider. We offer professional laser marking services, allowing us to accurately etch your company's brand, logo, or specific part markings directly onto the metal surface of the fittings, ensuring a professional presentation for your inventory.
A: Our standard and preferred payment term to ensure secure and efficient transaction processing is T/T (Telegraphic Transfer).
