Sight Glasses FAQ
What engineers ask before they specify this category.
What pressure can a sight glass take
It depends on the glass size, body style and temperature. Give the line size, working pressure and peak CIP or SIP temperature and we will confirm the rating for the specific model before you order.
Do you offer a lit sight glass
Yes, there are versions with an integrated wire light, intended for looking into dark vessels and product lines.
How do I clean a sight glass in place
Fit it where cleaning solution flows across the glass face rather than in a dead branch, and keep the flow velocity at the same figure as the rest of the line. We can advise on orientation for your layout.
Get Sight Glasses Quoted Against Your Duty
Send the line size, media, working pressure, temperature and the standard you work to, and we will confirm dimensions, material and finish in writing.
