Easy to Work With
LJ Star is easier to work with than other suppliers because our customer service staff has an industry-leading command of technical requirements and documentation. We recommend the sight glasses, sight flow indicators, sanitary fittings and other products that best suit your processing needs. Orders are processed quickly and correctly the first time.

Industry Proven Products
We offer the No. 1 selling fused sight glass, installed in more plants around the world than any other brand. A unique combination of metal and glass formulas make Metaglas sight glasses 4.5x stronger than comparable products. The results are superior safety, a wider operating range, and a long, worry-free service life.

Unlike other sight glasses, Metaglas meets stringent quality standards such as DIN 7079, DIN 7080, ASME BPE-2005, and ASTM E438, and it is approved for USP Type I use. See competitor comparison chart to compare features.

3rd Party Documentation
Beware of misleading claims about product performance. We provide third-party documentation so you know your sight glass will perform as promised.

Fast Delivery
In many cases, standard ship times are within 24 hours. By manufacturing our sight flow indicators domestically, we cut delivery time in half compared with suppliers who manufacture overseas. And our inventory is 50 percent larger than most competitors, enabling fast delivery.
