PAC-RTJ excels in high-pressure applications such as oil and gas exploration and production. RTJs are also used on valves and pipework assemblies in refineries and other process industries. Available in both oval and octagonal profiles, standard style R ring type joints are manufactured to meet both API 6A and ASME B16.20 sizes and ratings. Also available are Style RX ring type joints which energizes on assembly. This type is designed to fit the same groove as a style R therefore making them interchangeable. For very high pressures, often found in sub-sea wellhead and Christmas tree systems, the style BX is used. Subsea versions of all styles are available with pressure balance holes. We also design and manufacture special RTJ and bespoke solid metal gaskets for topside and subsea blow-out preventers.
