Monitoring fluid levels and flow is easier with a sight glass, and this liquid sight glass 3940/7 with a diameter of 22 mm is designed for that purpose. It allows you to visually inspect the liquid inside pipes or tanks without opening the system, which is invaluable during boiler maintenance and repair. The 22 mm size fits standard openings, and the robust construction ensures durability under pressure. This sight glass is a practical addition to any heating equipment, providing a clear view of the fluid condition. Whether for oil or water systems, it helps in early detection of issues like contamination or air bubbles.
