SS Joint Gaskets (RTJ)
Our high-performance Stainless Steel (SS) Ring Joint Gaskets are precision-machined to perfection from premium grades including SS 304, SS 316, SS 316L, and SS 321. Available in both Oval and Octagonal configurations, these solid metallic gaskets provide unparalleled resistance to corrosion, aggressive chemicals, and high-temperature oxidation. By maintaining meticulous heat treatment processes, we ensure our stainless steel RTJ gaskets achieve the exact hardness differential required to yield a flawless, bubble-tight seal in high-pressure wellhead manifolds, process piping, and offshore extraction networks.
Key Features
✓ Precision-Engineered Metal-to-Metal Sealing
✓ Extreme Pressure Resistance (Up to 20,000 PSI)
✓ Strict Hardness Control to Protect Flange Grooves
✓ Available in Oval, Octagonal, and BX/RX Profiles
