Raised Face (RF) Gasket

The Raised Face (RF) Gasket is one of the most widely used sealing solutions in industrial piping systems. Specifically designed to seat on the raised portion of the flange face, this gasket type ensures that sealing pressure is concentrated on a smaller contact area, creating a highly effective and reliable seal. Because of this efficient design, RF gaskets are the standard choice in process piping where dependable leakage prevention is critical.

Manufactured in a variety of materials—including Compressed Non-Asbestos Fiber (CNAF), graphite, PTFE, and rubber—these gaskets can be tailored to meet diverse application requirements. CNAF and graphite are particularly suited for high-temperature and high-pressure environments, while PTFE and rubber provide excellent resistance to chemical attack, making them ideal for corrosive or low-pressure service.

RF gaskets are fully compatible with ASME B16.5 raised face flanges, which are the most common flange type in oil & gas, chemical processing, petrochemical, water treatment, power generation, and general industrial systems. Their versatility ensures they can be used across a wide range of media, including steam, oil, gas, water, and aggressive chemicals.

In addition to their performance, RF gaskets are valued for their cost-effectiveness and ease of installation. Their simple design allows for quick replacement during routine maintenance and shutdowns, helping minimize downtime. The raised face design also helps protect the sealing surface of the flange by limiting contact to the gasketed area, extending the service life of both the gasket and the flange.

Overall, Raised Face gaskets remain the industry standard sealing solution for process piping systems, combining reliability, adaptability, and economy. Whether for critical service in refineries or standard duties in utility lines, RF gaskets provide a trusted and proven method of ensuring leak-tight connections.
