The RX Ring Gasket is a pressure‑energized metallic sealing solution designed for high‑pressure Ring Type Joint (RTJ) flange connections. Manufactured in accordance with API 6A and ASME B16.20 requirements, these gaskets provide reliable metal‑to‑metal sealing performance in critical oilfield and industrial applications. Engineered to fit standard R-type flat bottom ring grooves, the RX profile enhances sealing efficiency by using internal system pressure to increase gasket loading within the groove, making it highly effective in demanding operating environments. RX Ring Gaskets are commonly installed in wellhead equipment, high‑pressure valves, Christmas tree systems, and other pressure‑containing assemblies where sealing integrity and operational safety are essential.
Gaskets Enquiry Form
The RX Ring Gasket is a specialized RTJ gasket developed for higher‑pressure applications than standard R‑series ring gaskets. Its pressure‑energized design allows system pressure to assist in creating a tighter seal as operating pressure increases.
Manufactured from solid metallic materials, RX RTJ Gaskets are designed to fit standard R‑type ring grooves used in both ASME and API RTJ flange systems, creating a dependable metal‑to‑metal seal. This design minimizes leakage risks in demanding service conditions and supports long‑term performance in critical pressure systems. The gasket profile is engineered to deliver improved sealing effectiveness while maintaining compatibility with specified flange configurations.

Material Options
RX Ring Gaskets are manufactured using a range of metallic materials selected according to pressure, temperature, and media compatibility requirements.
Soft Iron
Commonly used for carbon steel flanges in standard oil and gas applications where excellent seating characteristics are required.
Carbon Steel
Suitable for general industrial services operating under controlled process conditions.
Stainless Steel (304, 316, 316L)
Provides improved corrosion resistance for petrochemical plants, offshore facilities, chemical processing, and marine environments.
Duplex Stainless Steel
Offers enhanced strength and resistance to chloride-induced corrosion, making it suitable for aggressive offshore applications.
Inconel 625, 718
Ideal for high-temperature service and aggressive chemical environments requiring superior oxidation resistance.
Monel
Widely selected for seawater service, marine applications, and hydrofluoric acid environments.
Material selection should consider flange hardness, corrosion resistance requirements, operating temperatures, and process fluid characteristics. Nickel-based alloys and stainless steels are commonly specified for corrosive service environments, while soft iron remains suitable for many standard applications.
