At MEREFSA, we offer a wide variety of encapsulated silicone seals, designed to ensure high performance in demanding applications. We provide models encapsulated in FEP, PFA, and PTFE, in various formats such as O-ring, rectangular, or oval, as well as options with Camlock closures, adapting to the specific needs of each industrial application.
Product Information
Encapsulated Seals of high quality, designed for applications that require optimal sealing. We offer encapsulated seals in FEP or PFA with a silicone, FKM, or EPDM core, in various formats such as O-ring, square, rectangular, oval, and with Camlock closures.
These seals can be manufactured in solid or hollow versions, with no diameter limitations for O-rings.
When to use Silicone Encapsulated Seals?
They are the ideal solution for applications where the use of conventional rubbers is prohibited, such as in the food, chemical, and pharmaceutical industries. In environments where corrosion or high temperatures may prematurely degrade O-rings, compromising their sealing capability, silicone encapsulated seals offer greater resistance and durability, ensuring optimal long-term performance.
When to use FKM encapsulated gaskets?
They are recommended for applications that require high resistance to corrosion and extreme temperatures, both high and low. They are particularly suitable for environments where the use of conventional rubbers is prohibited due to the presence of aggressive substances such as acids, solvents, and hydrocarbons. In these cases, the use of encapsulated FKM O-rings prevents premature deterioration and ensures the system's sealing integrity.
Material Comparison for O-Rings
Pure PTFE O-Rings: PTFE is an inert material with excellent chemical resistance. However, due to its rigidity and lack of elastic memory, it is not suitable for use as a compression seal. Once disassembled, the seal loses its sealing capability, which limits its reusability.
PTFE Sandwich Seals: While they are a cost-effective option, their design features high permeability on the sides, which reduces their effectiveness and makes them vulnerable to chemical attacks. This makes them a less durable solution in demanding applications.
PTFE Coated O-Rings: O-rings coated with acrylic or latex emulsions with PTFE offer a low friction coefficient. However, they lack significant chemical resistance, and their coating deteriorates easily, which limits their usefulness in aggressive industrial environments.
Perfluoroelastomer O-Rings: This material represents the most advanced solution in terms of chemical resistance and operational temperature range. However, its high cost limits its viability for many industrial applications, being reserved only for critical situations.
Metal O-Rings: These offer excellent chemical resistance and optimal performance in high-pressure applications. However, their rigidity and high cost can be drawbacks in certain applications where greater flexibility is required.
Encapsulated Seals: Flexibility + Resistance
Silicone Encapsulated O-Rings: Designed for static applications, combining the chemical resistance of FEP or PFA with the flexibility of a silicone core. They are recommended for applications that require FDA certification or contact with food, as silicone allows for a temperature range of -60 °C to +260 °C. The FEP coating offers good chemical resistance, although with a more limited temperature range, while PFA withstands temperatures up to +260 °C and provides greater resistance to abrasion and pressure.
FKM Encapsulated O-Rings: Designed for static applications, these encapsulate a fluoroelastomer (FKM) core in FEP or PFA, offering an optimal combination of chemical resistance and flexibility. The FKM core, with a temperature range of -20 °C to +204 °C, provides superior chemical resistance compared to silicone. As with silicone encapsulated seals, the FEP coating limits its temperature range, while PFA, with thermal stability up to +260 °C, ensures greater resistance to abrasion and pressure.
Available in multiple formats (O-ring, square, rectangular, oval, and with Camlock closures), these seals can be manufactured in solid or hollow versions. Additionally, we offer O-rings with no diameter restrictions, adapting to the specific needs of each client.
