🔷 What is a Ring Type Joint (RTJ) Gasket?

A Ring Type Joint (RTJ) Gasket is a precision-machined metallic ring designed to fit into specially machined RTJ flange grooves.

When the flange bolts are tightened, the gasket undergoes controlled deformation, creating a metal-to-metal seal capable of withstanding extreme pressures and temperatures.

RTJ gaskets are specifically used in:

✔ High-pressure systems
✔ Offshore drilling platforms
✔ Subsea pipelines
✔ Critical oil & gas operations
