Ring Type Joint (RTJ) Gaskets

Metallic RTJ gaskets for high-pressure and high-temperature flange connections, including oval and octagonal profiles.

Product overview

Ring Type Joint gaskets are precision-machined solid metallic seals used in specially grooved flanges for high-pressure service. Oval and octagonal cross-sections are widely used. Correct material hardness, ring number, flange groove condition and dimensional standard are critical to reliable performance.
