This flat gasket is commonly used in industrial and commercial systems such as fuel lines, oil transfer and solar thermal installations. It is suitable for applications involving mineral oils, fuels and glycol-based heat transfer fluids. The gasket ensures tight sealing in environments where temperature fluctuations are frequent, making it ideal for both indoor and outdoor mechanical systems.

The installation typically involves fitting the gasket between flanged components, ensuring a secure and leak-free joint. Due to the wide operating temperature range, it is particularly useful in systems exposed to extreme weather conditions or those operating near heat sources. Correct sizing and alignment are essential to maintain system integrity over time.

Technical parameters

The nominal pressure rating of PN 16 indicates the maximum allowable working pressure under standard operating conditions. The specified minimum operating temperature of -20°C allows for use in cold climates or refrigerated environments. These parameters are critical when selecting the appropriate gasket for a given application to ensure long-term performance and resistance to thermal cycling.

Installation and connection

For proper installation, the mating surfaces must be clean and free of debris to prevent uneven compression of the gasket material. The gasket should be placed centrally within the flange groove to avoid misalignment during tightening. Threaded or flanged connections are common methods for securing the joint. Installers should use a torque wrench to apply even tightening force and follow the manufacturer’s recommended sequence to prevent distortion. Common mistakes include over-tightening, which can damage the gasket, and using incompatible fasteners that may cause corrosion.

Compatibility and accessories

This gasket is compatible with flanged pipe systems designed for mineral oils, fuels and glycol-based media. To complete the assembly, installers may need to order additional components such as bolts, nuts and washers according to the specific flange type and size. It is important to verify the compatibility of all mating parts before installation to ensure a leak-free seal.

Technical background for designers

This material remains flexible across a broad temperature range, allowing it to adapt to dynamic loading and thermal expansion. When integrated into a system, the gasket forms a compressible layer that fills irregularities between flanges. The sealing effectiveness depends on surface finish, flange parallelism and the uniformity of clamping force applied during installation.

Service and operation

During routine maintenance, inspect the gasket visually for signs of wear, cracking or hardening, especially after prolonged exposure to high temperatures. The integrity of the joint should also be checked for leaks or corrosion around the flange edges. While no specific service interval is provided in the documentation, regular inspections are recommended in high-cycling or high-temperature applications to ensure continued performance.
