Specifications

A spectacle blind is a machined product used to safely isolate a section of a pipeline. This is typically used instead of a valve when a section needs to be isolated for an extended period.

Hendrix Fabrication’s spectacle blinds are available in sizes that range from 1/2” to 54” in diameter, with pressure ratings from 150# to 2,500#.

They are available in a variety of materials including Carbon Steels, Stainless Steels, Chrome-Moly, and more alloys.

Our spectacle blinds are available with different faces and connections, including Raised Face, RTJ (male and female), and are available in different machine finishes – such as “Mill Finish” or “Serrated Machine Finish”.
