L.J. Star Announces Metaglas Sight Glass For Chemical And Pharmaceutical Processing

Twinsburg, OH - L.J. Star announced that it offers a full line of Metaglas® sight glass products. Made by fusing pure borosilicate glass within a stainless steel ring, the result is prestressed glass with the strength of steel.

Metaglas is 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 glass designs, Metaglas meets stringent quality standards such as DIN 7079, DIN 7080, ASME BPE, and ASTM E438, and it is approved for USP Type I use.

Metaglas sight glass windows are suitable for general applications and aseptic use, including applications in flange sight ports, circular weld pads, visual flow indicators, threaded ferrule sight ports and sanitary clamps. The metal component is standard as duplex stainless steel but carbon steel and Hastelloy "C" is also available.

These products serve a wide variety of applications: threaded sight glasses in hazardous locations, compression chambers, sight glass illumination, fluid measurement and turbulence in gear housings. Special ANSI bolt-on flanges for flat faced flanges are also available.

Testing has shown the Metaglas sight glass to be safe at pressures far exceeding rated pressure. A video shows a Metaglas sight glass under 20 times normal pressure being struck with a steel projectile. Although the surface is chipped, the sight glass remains leak tight.
