HMT - Model Econo-Flex -Rim-Mounted Compression Plate Type Wiper Secondary Seal
The HMT Econo-Flex Secondary Seal is one of the most economical and effective types of secondary seals available. Easily installed and maintained, the HMT Econo-Flex Secondary Seal was designed under the guidance of the stringent gap specifications for secondary seals from governmental regulatory agencies throughout the U.S., including Northern California’s BAAQMD and its “zero-gap” requirements. For a secondary seal that is custom-designed to fit specific tank round anomalies, has exceptional gap sealing ability, allows for in-service installation, and has a long service life, choose the Econo-Flex Secondary Seal.
Sized specifically to each tank and constructed from custom-hardened stainless steel to ensure tension will hold up year after year, the HMT Econo-Flex will maintain a tight seal over time.
All HMT pressure-application components are made from custom-hardened stainless steel to prevent yielding under load, ensuring spring longevity and long-lasting seal performance.
The HMT Econo-Flex features a wiper tip that conforms tightly to the tank shell, minimizing ingress of rainwater into the stored product.
Bolt-on design means no hot work is required.
Meets Northern California’s BAAQMD stringent “zero-gap” requirements
Custom-hardened steel will not fatigue over time, maintaining proper sealing pressure against the tank shell and preventing gaps over the life of the seal.
