Product catalog summary

Overview: The document provides technical specifications and usage guidelines for the Circular Sight Glass Fitting Type 394, designed for visual inspections in pipelines, boilers, tanks, and various apparatus. It is suitable for both liquid and gaseous media and can be customized for specific applications.

Specifications:

Temperature Range: Up to 280°C, depending on glass and gasket materials.
Pressure Range: 16 barg to 160 barg, with higher pressures available upon request.
Materials: Base flange made of 1.4571 or 1.4404, borosilicate glass (DIN 7080 or similar), and various gasket materials including PTFE, FKM, NBR, C4400, Silicone, EPDM, and Graphite.

Installation Notes: The screw connection requires appropriate sealing material to achieve the specified pressure rating, as the connecting thread is not self-sealing.

Product Structure:

Components include screws, cover flange, glass cushion, sight glass, gasket, and base flange with threaded connection.
Product code example: 11-394-2-1-2-1-4-0, indicating standard version with specific materials and configurations.
