Stainless Steel RTJ Gaskets

Stainless Steel RTJ Gaskets, SS Oval & Octagonal Ring-Type Joint Gaskets Supplier in Mumbai, India

Unifit Metal Alloys is a manufacturer, supplier, stockist and exporter of Stainless Steel Ring-Type Joint (RTJ) Gaskets in Mumbai, India, supplying metallic sealing products for high-pressure piping, valves, pressure vessels and demanding industrial systems. These gaskets are manufactured from stainless steel materials selected for their strength, corrosion resistance and suitability for elevated-temperature service. We offer different ring profiles, dimensions, material grades and specifications to meet a wide range of flange sealing requirements. Standard and customized sizes can also be supplied.

Stainless Steel RTJ Gaskets are designed to fit into precision-machined ring grooves between RTJ flanges. When the flange assembly is tightened, the metallic ring is compressed against the groove surfaces to establish a dependable metal-to-metal seal. This sealing arrangement helps contain pressurized liquids and gases and is particularly suitable for applications where high sealing reliability is required.
