Products / Flexitallic / Ring Type Joints

The metallic Ring Type Joint is used in the petroleum industry, where high pressure applications necessitate the need for a high integrity seal.

Every RTJ that leaves the Flexitallic manufacturing facility is identified with key product information to give you the confidence that their products meet stringent application requirements.

In addition, every material that enters their factory is checked using the latest Positive Material Identification (PMI) technology, which combined with their material database, ensures they have full product traceability.

RTJ’s were initially developed for use in the upstream petroleum industry and are also commonly used on valves and pipework assemblies, and high integrity pressure vessels.
