Product Description

Seals Ring Oval RTJ Gasket


The ring type joint gaskets are either octagonal or oval in cross-sectional. RTJ gaskets are typically used for high pressure and high-temperature applications. It is widely used in refinery, petrochemical and oil field drilling industries. The Ring type joints gaskets are factory-made as per ASME B16.20. They are dimensionally suitable for use with flanges manufactured as per standards ASME B 16.5, ASME B16.47, and API 6A. The axial compressive load (due to bolt tightening) act on the Ring type joint(RTJ) gasket inflicting them to deform and flow into irregularities of projection grooves. Because of this, a metal-to-metal contact is formed between gasket and flange that makes a seal.

The ring sort joints have a superb tightness and tolerance to temperature and pressure changes. While putting in a ring type joint gasket terribly close attention should be given to their bolting up for uniform load functioning on the gasket. Also, confirm the RTJ gasket and groove faces should be freed from imperfections and scrap.



As a result of metal to metal sealing media they are made to be free of indentations, tool marks etc and have a surface finish of maximum,


· R, RX – 63 microinches Ra (1.6 micrometer Ra).

Thus Gasket supplies ring joint gaskets (RTJ Gasket) with the hardness numbers as follows:
