Grooved couplings are mechanical pipe connections that utilize grooves to interlock pipes. These couplings are widely employed in various grooved piping systems, including water supply, fire protection, HVAC, and process piping systems. The fundamental design of a grooved coupling comprises two grooved-end fittings with a gasket placed in between, which is secured using bolts or clamps.

Grooved reducers are utilized in piping systems and various industrial applications to connect pipes of different sizes. They are often referred to as "reducing couplings" because they reduce the pipe size from one end to the other. The grooves on the fittings refer to a specific type of connection method employed to securely join the pipes. Grooved reducers typically feature different diameters at each end, with the larger end being grooved.

A grooved tee is a type of pipe fitting used to connect three pipes at a T-junction. It is named after the grooves present at the end of each pipe, which allow for quick and easy connection using mechanical couplings. Grooved tees are commonly used in various industrial applications that require high reliability and efficiency of the piping system.

Grooved cross is a type of pipe fitting used to connect four pipes at a common intersection. The end of a grooved cross is connected to the pipes through grooves or threads, forming a strong and leak-proof joint.

A grooved elbow refers to a pipe fitting with grooves at its ends, designed for connecting two pipes at various angles. The grooved end of the elbow features a series of small dents or grooves, allowing easy and secure connection to the pipe using mechanical couplings or clamps.

Grooved flanges are widely used in piping and HVAC systems to connect pipes of different sizes and materials. A grooved flange is a type of pipe fitting with grooves or dents around its circumference, facilitating easy and secure connection to grooved-end pipes. The grooves on the flange are typically evenly spaced and designed to align with corresponding grooves on the grooved-end pipe.

Grooved end caps are designed for grooved pipeline systems. A grooved pipeline system is a type of pipe joint that uses a series of grooves and special fittings at the ends of pipes to form a secure and leak-free connection. Grooved end caps are typically used to cover the end of a grooved pipeline, effectively sealing it and preventing the flow of fluid or gas through the pipe.
