Hygienic Butt welding inline sight glass

Hygienic Butt Welding Inline Sight Glasses are permanent, leak-proof viewing ports integrated directly into process piping. By welding the housing into the line, "dead spaces" and gasket leak points associated with clamps are eliminated. They feature a borosilicate glass cylinder protected by a 316L Stainless Steel frame. Designed for high-pressure and high-temperature CIP/SIP environments, they provide a smooth, continuous flow path for sterile monitoring in pharmaceutical and biotech systems.
