JIC 37-degree Flare Hydraulic Fittings Weld Adapter
The JIC 37-degree Flare Hydraulic Fittings Weld Adapter has several key features:
1. Precise 37-Degree Flare Angle : Designed to provide a reliable and leak-proof seal by creating a tight connection at a 37-degree flare angle, which ensures secure fitting under high-pressure conditions.
2. Weldable Design: The adapter is equipped with a weldable end, allowing it to be securely welded to pipes or other components, ensuring a strong and permanent connection.
3. Durability: Made from high-quality materials, such as stainless steel, to withstand harsh environments and high-pressure systems, providing long-lasting performance.
4. Versatile Application: Commonly used in hydraulic systems, including fluid power systems and heavy machinery, for connecting hoses or pipes to different components.
5. Corrosion Resistance: Often manufactured with corrosion-resistant materials, making it ideal for applications in industries such as oil, automotive, and industrial machinery.
6. Easy Installation: The flare design simplifies installation, as the fitting provides a reliable, tight connection without the need for additional sealing components like O-rings or gaskets.
7. High-Pressure Capability: It is engineered to withstand high-pressure conditions, ensuring safety and reliability in demanding hydraulic applications.
This combination of features makes the JIC 37-degree Flare Hydraulic Fittings Weld Adapter an essential component for hydraulic systems requiring durable, high-pressure connections.
JIC 37-degree Flare Hydraulic Fittings Weld End Connector are made of stainless steel, a straight adapter. One end will be welded to hold on the metal tube or metal equipment and another is taper seat with UN / UNF thread to connect crimp hose fittings or JIC 37-degree swivel female fittings.
Hydraulic fitting series provides a variety of selection, including straight unions, 45-degree elbows, 90-degree elbows, Tees, nuts, plugs and caps. Flare design adopts taper metal sealing technology to provide crack resistance withing worrying about temperature and fluid.
