Seal King® Secondary Seal
Low-profile secondary seal
The Seal King low-profile secondary seal was specifically designed to give the ability to maximize tank working capacity. With its extremely low profile, the Seal King increases the working capacity of a floating roof tank, allowing to increase competitiveness and profitability. The Seal King also has unsurpassed vapor-sealing ability and exceptional water-shedding capability.

Benefits
- Low profile to increase working capacity
The low profile allows operators to increase storage tank capacity by increasing the safe fill height of their tanks. In addition, for tanks with 12 m foam chamber spacing, the Seal King allows for reduced foam dam height and cost. - No gapping
The Seal King has exceptional range and pressure application, ensuring a tight-fitting seal and no gaps. - Excellent weather shedding
The tight pressure distribution and good working area provide good weather protection and minimise rainwater ingress. - Long life
Fully hardened stainless steel spring components and a solid PTFE-encased scraper tip ensure long-lasting sealing performance. - Easy fabric inspection

Design features
Fully hardened stainless steel in pressurised system
Fully hardened stainless steel support arms maintain excellent sealing pressure and will not yield as rim spaces change, ensuring a good seal over time.
Abrasion-resistant wiper tip
The Seal King employs a solid PTFE-wrapped wiper tip, which performs well against tank shells due to its low coefficient of friction and excellent toughness.
Flexible assembly adapts to tank shells
The flexible nature of the Seal King assembly ensures it molds well to shell irregularities.
Multiple vapour barrier options
A range of vapor barrier fabrics can optimize for product compatibility or mechanical durability over time.
