SEALMASTER® PRIMARY & SECONDARY

The Sealmaster floating roof seal system was developed over 35 years ago, with the goal of making a seal that adjusts to the irregularities of tanks while remaining gas-tight and virtually maintenance-free. The solution is the Sealmaster seal system. The Sealmaster is comprised of fully hardened compression plates, extending from the floating roof rim to the tank shell and down into the stored product, thereby providing a non-combustible protective sheath over a fully-heat-welded vapor barrier encapsulating the entire vapor space.
