Secondary Seal
The secondary seal reduces evaporation losses from the primary seal and prevents rainwater or other contaminants from entering the stored product. The compression plate can be mounted on either horizontal or vertical roof rims and is designed to accommodate specific bolt spacing. Overlapping compression plates provide strong sealing pressure against the tank shell.
The wiper tip is made of UV- and weather-resistant synthetic rubber, ensuring high sealing efficiency. The shunts comply with API 2003.
