The Garlock® PS-Static Seal Gylon is a premium-quality flat sealing ring specifically designed for static applications. This means the seal is used in places where no movement occurs between the components, such as flange connections or covers. Thanks to its excellent chemical resistance and temperature tolerance, this seal is ideal for use in demanding industrial environments. The PS-Static Seal is available in various materials and dimensions and provides a reliable, leak-free seal with long-lasting performance. By minimizing leakage, it also helps prevent unplanned downtime, contributing to maximum uptime and the protection of critical equipment.
The PS-Static Seal is constructed as a flat ring, typically 1 mm thick, that is placed between two fixed surfaces. The seal is axially compressed and conforms to surface irregularities. This creates a tight seal without the need for a spring or moving parts. Garlock uses high-grade materials for these seals, such as Gylon® and FKM (Viton®). Gylon is an advanced PTFE-based material filled with additives that reduce the creep and cold flow typical of standard PTFE. This results in a gasket that remains stable under pressure and resists extrusion. The FKM variant, on the other hand, offers more flexibility and is suitable for situations requiring greater compression or elasticity.
These flat gaskets are used in industries where absolute reliability is essential. Examples include the chemical industry, where aggressive media must be sealed; the food and pharmaceutical sectors, where hygiene and certifications are crucial; and general machinery applications, where a reliable and low-maintenance seal is required. In all these cases, the PS-Static Seal provides an effective solution thanks to its material properties, resistance to high temperature and pressure, and long service life. Typical applications include flange joints, vessel covers, static parts of pumps and filters, and process equipment housings. Due to its high chemical resistance, the seal also prevents corrosion and wear on surrounding equipment, reducing the risk of damage and failure.
The PS-Static Seal is available in multiple material variants, each with specific characteristics:
|
Material |
Temperature Range |
Key Properties |
|
Gylon Blue (3504) |
-200°C to +260°C |
Versatile, chemically resistant, FDA compliant |
|
Gylon White (3510) |
-200°C to +260°C |
Highly resistant to chemicals (including bases), FDA compliant |
|
FKM (Viton) |
-20°C to +200°C |
Oil and fuel resistant, elastic, ideal for low compression |
Selecting the correct PS-Static Seal begins with accurately measuring the installation space. Key parameters include inner diameter (ID), outer diameter (OD), and thickness (typically 1 mm). For flange connections, it is important that the gasket fits properly within the bolt pattern and offers sufficient surface area to form a seal. Keep tolerances in mind: the seal must be lightly compressed to function properly. Ensure the OD is slightly larger than the recess to create tension during installation.
Material selection depends on the medium (chemical profile), operating temperature, and applicable regulations. For applications involving food or pharmaceutical contact, FDA compliance is required. In such cases, Gylon Blue and White are the best options. For oil and fuel applications or when elasticity is desired, FKM is a suitable alternative.
Also verify whether the seal conforms to industrial standards such as DIN or ANSI flange dimensions. Many PS-Static Seals are available in standard sizes aligned with these norms, but custom dimensions are also possible. Thanks to color coding (blue = Gylon Blue, white = Gylon White, black = Viton), the materials are easy to identify visually.
In summary, the Garlock PS-Static Seal Gylon® is a reliable sealing solution for static applications. Made from high-quality Gylon or FKM Viton material, these seals offer exceptional sealing capabilities and ensure minimal leakage. With Garlock's reputation for quality and reliability, the PS-Static Seal Gylon® provides the security and peace of mind you need for your static sealing requirements.

Yes, it is a flat, ring-shaped seal designed for static use between two surfaces.
No, reuse is not recommended. The material deforms upon removal and may lose its sealing performance.
Depending on the Gylon type, the range is -200°C to +260°C. Viton is suitable up to approx. +200°C.
Gylon is ideal for chemical resistance and temperature tolerance. FKM is better for oils, fuels, and elastic sealing needs.
Yes, Gylon Blue and White are FDA compliant and suitable for food and pharmaceutical applications.
