Couplings are used to connect two sections of pipe or tubing, allowing fluid or gas to pass through without interruption. Available in several designs, including compression, slip, and welded couplings, these fittings offer a simple yet effective solution for various applications. The main advantage of couplings is their ability to create secure connections while enabling ease of maintenance. They are commonly used in plumbing, gas, and water supply systems, as well as in industrial applications such as mining, construction, and oil & gas pipelines. Couplings are available in a wide range of materials to match the specific requirements of the system, such as brass, stainless steel, or carbon steel.
Brief:Our shouldered couplings are specially designed for high-pressure piping systems using shouldered-end steel pipes. Made of durable ductile iron and equipped with high-quality EPDM or NBR gaskets, they ensure a reliable, leak-free connection even in demanding environments such as mining, tunneling, and water infrastructure projects. Easy to install and remove, they are ideal for quick assembly, system maintenance, and long-term performance.
Brief:Our reducing flexible coupling is designed to connect pipes of different diameters while allowing for flexibility, vibration absorption, and easy installation. Made from high-strength ductile iron and fitted with EPDM or NBR gaskets, it provides a secure, leak-free connection under pressure. Ideal for fire protection, HVAC, and industrial piping systems, this coupling simplifies system design by eliminating the need for concentric reducers and additional joints.
Brief:The flexible coupling is a type of fitting designed to connect pipes using a specialized groove and seal ring mechanism. It helps to absorb pipe movement and vibrations, effectively minimizing the risk of pipe failure. This product makes pipe installation and removal easier while delivering superior sealing performance to maintain system integrity and reliability. Its versatility makes it ideal for use in fire protection, water supply, HVAC, petrochemical applications, and more, particularly in pipe systems that demand flexibility, seismic resistance, and leak-proof connections.
Brief:Angle Pad Coupling is a special fitting for pipe connection, usually used to connect two pipes at an angle. It ensures the sealing and stability between pipes by using special gaskets and steel clamps. Angle Pad Coupling is particularly suitable for occasions where pipe offset or cornering is required. It can withstand certain pressure and vibration while maintaining the overall stability and sealing performance of the pipe system.
This product is widely used in fire protection systems, heating, ventilation and air conditioning (HVAC) systems, water supply and drainage systems, and oil and gas industries. Especially in those occasions where space is limited or the direction of the pipe needs to be adjusted, Angle Pad Coupling provides a simple and effective solution. Due to its easy installation and high reliability, it has become one of the indispensable key accessories in the pipeline system.
Brief:HDPE Transition Coupling is a specially designed fitting used to connect HDPE pipes with metal pipes such as steel, copper, or PVC. One end is made of high-quality PE100 for fusion welding, while the other end is metal for threaded, welded, or flanged connections. This coupling ensures a strong, leak-free, and corrosion-resistant joint between different piping materials. Widely used in water supply, gas distribution, industrial piping, and fire protection systems, it provides a reliable and efficient solution for multi-material pipeline transitions.
Brief:Quick Rigid Coupling are accessories for quick connection and fixing of pipes. They are designed with a simple and fast installation method, usually without additional tools or welding. It ensures the firmness and sealing of pipe connections through a unique groove design and locking mechanism. Quick Rigid Coupling can effectively resist pressure fluctuations between pipes while avoiding leakage problems and providing reliable connections. This product is widely used in fire protection systems, building pipes, heating, ventilation and air conditioning (HVAC) systems, water supply and drainage pipes, etc. Especially in environments that require quick installation, disassembly or maintenance, Quick Rigid Coupling provides great convenience. In fire protection systems, it can ensure the safety and reliability of pipe connections; in HVAC and water supply pipes, it provides a simple and efficient connection solution, especially for places that require frequent maintenance and adjustment. Due to its high efficiency and convenience, Quick Rigid Coupling has been widely used in modern buildings and industrial piping systems.
