Stainless steel threaded couplings serve to connect straight pipe to straight pipe often in low-pressure systems. They are widely used in water, oil, natural gas, air, and other equipment, and are easy to replace and install.
Threaded stainless steel coupling is a connection fitting with female threads. The presence of internal threads makes the process of connecting pipes simple and fast, making it possible to quickly disassemble pipes or their components. Often used to connect other valves or stainless steel pipe fittings with male threads.
Commonly used threaded couplings include NPT or BSP threaded, with PTFE tape used to ensure a tight seal during use. NPT tapered threads ensure a secure and leak-proof connection, making them ideal for a variety of applications in many industries, including piping, chemical processing, oil and gas, and food processing.
Overview
Threaded fittings are used in commercial and industrial environments to transfer water, oil, gas, or air through a non-critical system. They are fast and economical components that are easily added to these systems. In addition, they require no welding so the system can be easily installed and modified.
