Frequently Asked Questions

What is the difference between reflex and transparent gauge glass?

Reflex gauge glass has prismatic grooves that reflect light differently depending on whether liquid or vapor is present, creating a clear visual contrast. Transparent gauge glass provides a direct view of the fluid level and is used when actual fluid clarity needs to be observed.

Can you customize gauge glass dimensions?

Yes, we offer custom cutting, shaping, and polishing services for gauge glass to meet specific equipment requirements. Contact us with your specifications for a quote.

What temperatures can your glass withstand?

Borosilicate glass: up to 300°C | Quartz glass: up to 1200°C | Soda-lime glass: up to 150°C. Exact limits depend on duration and pressure conditions.

Do you provide samples?

Yes, we offer free samples for qualified inquiries. Contact us to request sample materials based on your application needs.
