Spectacle Blinds / Figure-8 Blinds

Mill finishes or machined 125-250 RMS finishes are the most common finishes we produce, but we can finish them however you like. Additionally, RTJ (RJ) gasket surfaces can be provided in oval or octagonal form.

Yes. Let us know how you want the additional thickness machined down from the outside diameter to the raised face gasket area. This is not common and will require an additional fee.

Yes. First, we need to know if you prefer an RTJ (RJ) male or RTJ (RJ) female spectacle blind.

For a male RTJ blind, the gasket profile is machined onto the blind, but this isn't usually preferred because any damage to the gasket profile will render it unusable. For a female RTJ blind, the area for the gasket seating profile is machined into the blind. This is preferred because commonly available gaskets can be used between the blind and flange.

We also need to know the profile you'd like on your gasket surface.

For male RTJ blinds, the options are oval or octagonal. Female RTJ blinds are typically requested as octagonal, which has 3 sides on each mating area (like a flat bottom V).

We can accommodate whatever combination you require for your blinds!

Yes. We will manufacture your blind(s) with any additional feature you need.

Yes, carbon or carbon alloy steel spectacle blinds will be color coded in the webbing of the blind.
