Overview

Floating roof seals are critical components in storage tanks with floating roofs. Installed between the floating roof and the tank shell, they help minimise vapour loss, enhance environmental performance, and support safe, compliant operation.
As liquid levels rise and fall, the floating roof moves accordingly. Floating roof seals are engineered to accommodate this movement while maintaining a consistent seal against the tank wall, even under changing operating and environmental conditions.

Key Benefits

Floating roof seals play a critical role in supporting safe, efficient, and compliant storage tank
operation across a wide range of operating conditions.

Reduced vapour loss

Helps minimise vapour emissions and product loss from floating roof tanks.

Improved environmental performance

Supports environmental protection objectives and emissions control requirements across storage applications.

Enhanced operational safety

Contributes to safer tank operation by maintaining an effective seal under varying operating and environmental conditions.

Designed for roof movement

Accommodates changes in liquid level and temperature while maintaining consistent sealing integrity.

Long-term reliability

Engineered to perform reliably and consistently in demanding operating environments.

Applications and Sectors
