Ring-Type Joint (RTJ) Gaskets, RTJ Oval & Octagonal Ring Gaskets Supplier in Mumbai, India
Unifit Metal Alloys is a manufacturer, supplier, stockist and exporter of Ring-Type Joint (RTJ) Gaskets in Mumbai, India, supplying high-integrity sealing components for piping systems, pressure equipment, valves and industrial process applications. These gaskets are manufactured from metallic materials selected to withstand high pressure, elevated temperatures and demanding operating environments. We offer different ring sizes, profiles, materials and specifications to suit various flange and sealing requirements. Standard and customized dimensions can also be supplied.
Ring-Type Joint (RTJ) Gaskets are installed in specially machined ring grooves between compatible flanges to create a reliable metal-to-metal seal. During tightening, the gasket is compressed into the flange groove, forming a tight sealing contact that helps prevent the escape of process fluids or gases. Their robust construction makes them suitable for applications where conventional soft gaskets may not provide the required sealing performance.
