Learn the correct torque specifications for RX ring joint flanges to ensure leak-free connections in high-pressure applications.

An octagonal ring joint gasket works by being compressed between two mating flanges, creating a tight metal-to-metal seal. Its octagonal shape provides multiple sealing surfaces that embed into the flange grooves under bolt load, ensuring a high-integrity, leak-proof connection suitable for high-pressure and high-temperature applications.

Oval ring joint gaskets are commonly made from metals such as soft iron, low carbon steel, stainless steel, and various alloys to withstand high-pressure and high-temperature environments.

This article outlines practical measures to prevent blowout and leakage in tanged metal reinforced graphite gaskets, focusing on correct installation, controlled bolt torque, and choosing the appropriate gasket material for specific operating conditions.

Pure expanded graphite gaskets generally have a higher initial cost than standard compressed fiber or rubber gaskets, but they are often more affordable than specialized materials like flexible graphite composites with costly metal reinforcements. Compared to PTFE gaskets, the price can be similar or slightly lower, depending on sheet thickness and grade. While the upfront expense is greater than many common non-metallic options, the superior chemical resistance, wide temperature range, and long service life of pure expanded graphite frequently result in a lower total cost of ownership through reduced maintenance, less downtime, and fewer replacements.

An exhaust spiral wound gasket is a high-performance seal designed for exhaust systems, built with alternating metal and filler layers to handle extreme temperatures, vibration, and pressure while preventing gas leaks.
