Mac-Weld offers both RTJ orifice plates, along with RTJ plate holder assemblies which include the required universal orifice plate.

RTJ Plate holders are a great solution for applications were frequent size changes or replacements are expected. Ring type joint orifice plates contain an intergral gasket that mounts between the ring tougue joint flanges.
