Sight Glass Products made using Compression are Stronger

Sight glass products need to be reliable. LJ Star provides high-strength, quality sight glass products for a variety of applications. Our sight glass is made with either borosilicate or soda lime glass resulting in the strongest and safest products for our customers.

We understand the importance of visual inspections for your process equipment. Our site glass products allow you to safely observe processes inside tanks, pipes, reactors and vessels. Our sight glasses are often used in conjunction with ex-lights and non-ex lights (luminaires) that light tank and pipe interiors for increased visibility.

L.J. Star will always provide third-party documentation of standards compliance and product performance claims.
