NPT 1-1/2″ Hastelloy C-22 Threaded Fused Sight Glass Borosilicate Window for Hydraulic Oils Compressed Air

Fanovo fused sight glass is ideal for use with all common hydraulic oils, refrigeration systems, water heaters, and compressed air applications. The glass-to-metal fusion process creates a robust, hermetically sealed one-piece component. This unique construction delivers exceptional glass strength, ensuring safe operation even during temperature cycling that occurs with regular equipment start and stop procedures. The product is easy to install and boasts a long service life with zero maintenance requirements. This sight window is equipped with NPT threads that conform to the ASME B1.20.1 standard. Note: The image of objects behind the glass may appear distorted near the edges of the aperture diameter. This is because the glass is slightly concave as a result of the fusion process.
