Sight Glasses for Vacuum Tanks

Sight glasses for vacuum tanks. Available with or without o-ring. 

A vacuum sight glass in a vacuum tanker application allows operators to visually monitor the contents inside the tank without interrupting the vacuum seal.

Operating in a temperature range of -15 to +60°C, sight glasses provide a clear view of the liquid or waste levels. Polycarbonate material.

Its design maintains the tank's vacuum integrity, even under varying temperature conditions, ensuring safe and efficient operation in industries like waste management, agriculture, and environmental services.

Male BSP parallel thread with a broad shoulder. Original Metaltecnica part.

For best results, use PTFE tape on thread to secure sight glass to the female socket in the vacuum tank. The o-ring is recommended to create a flexible join between the sight glass and vacuum tank as vacuum tankers and waste tanks experience vibration during transport and operation. The O-ring helps maintain the seal despite slight movement.
