MAXOS® BOROSILICATE CIRCULAR SIGHT GLASS
ANNULAR GLASS REPLACEMENT

As a size for size replacement for Pyrex Brand Annular Edge sight glass,
Maxos® is clearly a better choice!

Maxos® is molded from specially formulated borosilicate 8488 glass, which gives it a superior quality over cut and ground glass. The Maxos® molding process produces a uniform product with excellent optical clarity and greater thermal shock resistance at an economical price. Testing procedures subject the sight glass to 8 times its rated pressure for maximum user safety. The 8488-borosilicate features chemical attack resistance to all acids except hydrofluric and hot phosphoric. Maxos® disks are suitable for tempratures up to 572°F at atmospheric pressure. Shields* may be used on Maxos® disks as needed for service conditions.

For application assistance, please contact us with your service conditions: temperature, pressuire, media, and unsupported diameter. Service limitations will vary with the unsupported diameter, thickness of glass and the corrosive nature of the media.

Important Note: Regardless of the glass ratings shown, never exceed the gage manufacturer’s pressure limitations.

For futher information refer to the gage manufacturer’s installation,
operation and maintenance instruction manual.
