The Durlon® LT100 is a specialized gasket material engineered for low-torque, chemically aggressive environments. Its innovative construction chemically bonds expanded PTFE (ePTFE) to a peroxide-cured EPDM rubber base, offering the chemical resistance of PTFE and the flexibility of EPDM. This design delivers superior sealing under low bolt loads and varying temperatures, making it ideal for non-metallic and plastic flanges where torque limitations are critical. Its dual-rib profile and controlled PTFE thickness optimize performance for flat-face and raised-face flanges.
A one-piece PTFE shield enhances the chemical protection and sealing reliability of the LT100, particularly in corrosive or high-purity systems. Designed with FDA-compliant materials, it is well-suited for sensitive industries such as pharmaceuticals, food and beverage, and potable water. With excellent resistance across the pH spectrum (0–14), the LT100 provides a reliable solution for applications involving acids, caustics, gases, and a wide range of chemicals. Its durability, regulatory compliance, and adaptability across flange types make it a trusted choice for industries demanding dependable, low-stress sealing.
Durlon® LT100 is specifically engineered for high-integrity sealing in low-torque, chemically aggressive, and sanitary environments. It is an ideal solution for non-metallic and plastic flanges where bolt load limitations are a concern. Designed to perform across the full pH spectrum from 0 to 14, Durlon® LT100 excels in systems that handle acids, caustics, bleaches, gases, potable water, wastewater, and steam. It is particularly well-suited for highly regulated industries such as food and beverage, pharmaceuticals, and water treatment, where FDA compliance and sealing reliability are critical. The gasket's ability to maintain performance under fluctuating temperatures and pressures makes it a dependable choice for corrosive fluid handling in chemical processing and semiconductor manufacturing. Additionally, it is an excellent sealing option for FRP and glass-lined piping used in industries such as mining, pulp and paper, and electronics.
Durlon® LT100 is a molded composite gasket manufactured by chemically bonding expanded PTFE (ePTFE) to a peroxide-cured EPDM rubber base. This proprietary formulation combines the superior chemical resistance and non-stick properties of PTFE with the flexibility and low compression set of EPDM. The gasket features a one-piece PTFE shield that spans the entire surface, providing full-face chemical protection and enhancing sealing performance. Its dual-rib design ensures compatibility with both flat-face and raised-face flanges, making it versatile across a range of flange types. The material exhibits low creep relaxation and requires minimal bolt load, which contributes to its long-term sealing reliability. With M&Y values of M = 1.5 and Y = 300 psi, Durlon® LT100 delivers consistent mechanical performance while resisting permeation, deformation, and chemical degradation.
