"RTJ" (Ring Type Joint) gaskets are manufactured in accordance with API-6A and ANSI B16.20 specifications. RTJ's have "R" numbers assigned to them for pipe size and pressure class identification. Stock materials include soft iron, low carbon steel, 4-6 chrome (f5), 304, 304L, 316, 316L, 347, Monel, Inconel and Incoloy.
API Ring Joint Gaskets
API Ring Joint Gaskets come in two basic types, an oval cross section and an octagonal cross section. These basic shapes are used in pressures up to 10,000 psi. The dimensions are standardized and require specially grooved flanges. The octagonal cross section has a higher
sealing efficiency than the oval and would be the preferred gasket. However, only the oval cross section can be used in the old type round bottom groove. The newer flat bottom groove design will accept either the oval or the octagonal cross section. The sealing surfaces on the ring joint grooves must be smoothly finished to 63 Microinches and be free of objectionable ridges, tool or chatter marks. They seal by an initial line contact or a wedging action as the compressive forces are applied. The hardness of the ring should always be less than the hardness of the flanges.

BX and RX Ring Gaskets
The BX ring gasket differs from the standard oval or octagonal shape in that it is square in cross section and
tapers in each corner. BX can only be used in API 6BX flanges. RX ring gaskets are similar in shape to the standard octagonal ring joint gasket but their cross section is designed to take advantage of the contained fluid pressure is effecting a seal. They are both made to API 6A.
