Experts in sight glass precision

Sight glasses, also called sight windows or view ports, comprise two flanges, bolted together, surrounding a glass disc sealed with gaskets and provides a means of viewing the inside of a process vessel or tank.

Custom sight glasses are uniquely designed to suit your application. Available for a wide range of pressures and temperatures, which are dictated by the viewing area, material specification and working environment.

METAGLAS® can replace conventional glass in many applications including circular flange assemblies for welding into vessels, weld neck & nozzle flanges and sight flow indicators.

Our sight glass light products (also called” luminaires”) illuminate process vessel interiors in pharmaceutical, food processing, and chemical plants. Available in standard and explosion-proof {ex-lights} housings LED designs.

A sight flow indicator is used in process pipelines to observe the flow of liquid, powder or gas. We also offer standard view and full-view sight flow indicators for industrial, sterile and hygienic applications.

A rupture disc, also known as a bursting disc, is a non-reclosing pressure relief safety device that, in most cases, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.

Designed to be used with pressure vessels and tanks, pipelines, reactor vessels and autoclaves, our clamps offer a quick release alternative to conventional bolting systems and avoid the need for the vessel closure to be flanged and drilled.

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