Ring joint gaskets, also called RTJ gaskets, form metal-to-metal seals in flanged equipment designed with a matching ring groove. KASIN lists R, RX and BX profiles, with products covering soft iron, carbon steel and selected alloy materials. These gaskets are used in oil and gas and other high-pressure systems, but the ring type and number must follow the specified flange and groove geometry.
Compare BX ring joint gaskets and R-type ring joint gaskets when reviewing existing flange specifications. These gasket types must not be treated as universally interchangeable.
RTJ sealing depends on controlled metal contact, so flange groove damage, ring re-use and incorrect bolt load can compromise a properly specified gasket. Procurement teams should treat the flange standard, ring number and material as linked fields on the purchase order. A generic reference to an RTJ gasket is rarely sufficient for a critical high-pressure joint.
Buyers should confirm ring designation, exact ring number, flange standard, groove condition, pressure-temperature limits and gasket material. Surface finish, hardness and installation procedures influence sealing performance. The BX160 API 6A gasket is one product-specific reference; any certification claim should be checked against its documentation.
