Pathan Durgadevi Udyan, Ground Floor, 25 Plot No 74/80, Patra Chawl, Maruti , Mandir Marg, Second Street, Girgaon, Mumbai, Maharashtra 400004Female Fittings’ is a term that is also used to describe piping and tubing components Female Adaptors. Typically, they are used to join any component that possesses an external, or “male,” connection—typically male threads, a ferrule, or a spigot end. The feature that defines this component type is its internally machined recess, which functions to help seal against an opposing male component.
At Tubotech, a top piping and tubing components manufacturer in India we offer you a wide range of high-quality Female Adaptors that are designed to ensure secure, leak-proof connections in a variety of industrial piping and tubing systems.More importantly, we ensure that they are manufactured using ‘Precision Engineering’ so that they offer ‘Durability’ and ‘High-Performance’.
Above all, we make sure that all our Female Adaptors are manufactured in a manner that help meet global standards for safety, strength, and reliability.
