Grooved fittings are pipe fittings that feature a grooved design, which allows for quick and easy installation using mechanical couplings. These fittings are made from various materials such as carbon steel, stainless steel, and aluminum, offering a versatile range of applications. The primary benefit of grooved fittings is their speed of installation—no welding or threading is required. They are often used in fire protection systems, industrial piping, and HVAC installations, particularly in environments that demand quick, easy, and reliable connections. Grooved fittings also provide high flexibility and are excellent for systems that require frequent maintenance and upgrades.
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:45° elbow in the groove is to change the direction of the pipe, and it is usually used in places where a small angle is required. It can bend the pipe at a 45-degree angle, which is suitable for slight changes in the direction of fluid flow. Compared with the 90-degree elbow, the 45-degree elbow can reduce the fluid resistance in the pipe, maintain a relatively smooth flow, and can effectively adjust the pipe layout in a small space. Due to its easy installation and good flow performance, the 45° elbow is widely used in fire protection systems, water supply pipelines and other fields.
Brief:The 90 elbow to change the direction of the pipeline, and it is usually used where the pipeline needs to turn. It can reduce the fluid resistance and pressure loss that may be caused by right-angle turns while ensuring the stability and smoothness of the pipeline system. Due to its simple design and convenient installation, the 90-degree elbow is widely used in fire protection pipelines, water supply pipelines and other systems.
Brief:The cross in the groove is to connect four pipes to form a cross structure. It is usually used in pipe systems that need to distribute or converge fluids in multiple directions, and can achieve effective connection between four pipes. In applications such as fire protection systems and water supply pipes, the cross can help the flexible layout of the pipe system to ensure the smooth flow of fluids in multiple directions. It is widely used in complex pipe networks, especially in situations where four pipes need to be connected at the same time.
Brief:The Tee is to branch or connect a pipeline to a main pipeline to form a T-shaped structure. It can achieve the distribution or convergence of fluids in different directions and is often used in pipeline systems that require diversion or convergence. In applications such as fire protection systems and water supply pipelines, tees can not only effectively change the direction of fluid flow, but also ensure the stability and smoothness of the pipeline system, and are particularly suitable for occasions that require quick installation and disassembly.
