Ring Joint Gasket
A Ring Gasket or Ring Type Joint Gasket (RTJ Gasket) is a precision sealing device designed to prevent leakage between two flange connections. These gaskets are engineered to sit within flange grooves and create a high-integrity seal when the flanges are tightened. For reliable and leak-free solutions, N-Pipe Solutions Inc. offers a comprehensive range of RTJ gaskets, crafted in accordance with industry standards such as API, DIN, BS, and ASME B16.20. Our gaskets ensure superior performance and durability across diverse industrial applications, including oil & gas, petrochemical, and power generation sectors.
Prime Features
R Type: Solid oval and octagonal sections for standard ring joint flanges with trapezoidal grooves.
RX and BX Types: Complex beveled edge sections for wellhead applications above 700 bar.
Combination Gaskets: Designed for connecting flanges of different sizes.
Split Gaskets: Suitable for joining API flanges with low-pressure ANSI flanges using spiral wound gaskets.
Custom Gaskets: Specially manufactured based on customer specifications.
