Our sight glass light products (also called "luminaires") illuminate process vessel interiors in pharmaceutical, food processing, and chemical plants. Choose from standard and explosion-proof (ex-lights) housings as well as halogen or LED designs.

Sanitary fittings from L.J. Star provide reliable, sanitary connections between process lines and components. Choose from a full line of sanitary clamps.

Our safety clamp improves operator safety with stainless sanitary fittings and is specifically targeted to hazardous high temperature steam lines.The newly designed and patented Safety Clamp improves operator safety throughout the industry. Developed using the template of our market leading SH Clamp, this new Safety Clamp specifically targets hazardous high temperature steam lines. Steam presents both high temperature and high pressure, so it is particularly important to use a safe clamp for pipe connections and sight glass mounting. The ‘gate’ style section combined with the stepped eyebolt assures the Safety Clamp’s bolting mechanism cannot swing open while the clamping union is part or fully assembled. Releasing the Safety Clamp is only possible when the wing-nut has been significantly loosened to enable the smaller diameter of the eyebolt to swing through the sectioned gate, ensuring the Safety Clamp cannot be knocked or accidentally opened. Complete wing-nut removal is not necessary to open the Safety Clamp since the design guarantees the eyebolt cannot swing open while the clamping union is subjected to either clamping forces or internal pressures.

Many applications use cameras to remotely observe the interiors of tanks, vessels, and reactors. L.J. Star video camera systems are easy to install on sight ports.

Our magnetic level gages and glass weld-on level gages provide simple and reliable indication of fluid levels in boilers, tanks, and process vessels.

Our hygienic bubble traps remove unwanted gas and bubbles from process fluids. They are specially designed for the pharmaceutical industry.

L.J. Star offers a full line of sight glass accessories, such as wipers, sprayers, light timers, heaters and replacement glass.
