Product Details
If corrosion resistance is only needed on wetted parts of a sight glass, our Model I Weld sight glass unit is an ideal choice for the application.

The Model I's insert can be made from a wide variety of materials (stainless steel, glass-lined, or Hastelloy, etc) to ensure compatibility with any process fluid, while the main unit body can be made of carbon steel (or any material your application requires). As with all PPC products, the Model I Weld can be made to meet any pressure and temperature requirements.
