The Fike 56-8095-030 4″ 316SS/TEF Rupture Disc is a precision-engineered pressure relief device designed to protect piping systems, pressure vessels, and process equipment from overpressure conditions. This rupture disc is constructed with a 316 stainless steel body and TEF (PTFE-based) sealing layer, providing strong corrosion resistance and compatibility with a wide range of gases and liquids. It is designed to burst at a calibrated pressure range of approximately 101.78 / 92.62 PSIG, with an operating temperature range of 71.6°F to 149°F, ensuring reliable protection within specified process limits.
In operation, the rupture disc acts as a non-reclosing safety device installed in a pressure relief system. When system pressure exceeds the rated burst value, the disc ruptures instantly to release pressure and prevent equipment failure or hazardous overpressure events. Once activated, the disc must be replaced, making it a critical one-time-use safety component. These discs are widely used in chemical processing, oil and gas operations, pharmaceutical production, food and beverage systems, and general industrial process control where precise pressure containment and fast-acting relief are required.
Because of its stainless steel construction and PTFE sealing layer, this model is especially suited for corrosive or clean-service applications where reliability, chemical resistance, and leak-tight performance are essential.
