SS 304/304L/316/316L/321 RTJ Gaskets

SS 304/304L/316/316L/321 RTJ Gasket, Stainless Steel Oval & Octagonal Ring-Type Joint Gasket Manufacturer & Supplier in India

Unifit Metal Alloys is a manufacturer, supplier, stockist and exporter of SS 304/304L/316/316L/321 RTJ Gaskets in Mumbai, India, supplying metallic sealing components for high-pressure flange connections, process piping, valves, pressure vessels and industrial equipment. These gaskets are manufactured from selected stainless steel grades to provide reliable sealing performance along with resistance to corrosion and elevated operating temperatures. We offer different ring profiles, dimensions and material specifications for various flange assemblies. Standard and customized sizes can also be supplied.

SS 304/304L/316/316L/321 RTJ Gaskets are installed into the precision-machined grooves of compatible ring-type joint flanges. As the flange bolts are tightened, the metallic gasket is forced against the groove surfaces, creating a concentrated metal-to-metal sealing line. This design provides dependable containment of pressurized fluids and gases and is suitable for applications where leakage prevention is a critical requirement.
