New Addition to Our Product Portfolio

Universal Gasket Sheet AFG-300 UT® Suitable for Hydrogen Applications

Reliable sealing is a key element for the safe and efficient operation of technological equipment, pipeline systems, and energy applications. That is why we are expanding our portfolio of compressed gasket materials with the new universal gasket sheet AFG-300 UT®, designed for a wide range of industrial applications.

The AFG-300 UT® gasket sheet is a modern sealing material that combines high mechanical strength, flexibility, and very good chemical resistance, providing stable and long-term reliable sealing even under demanding operating conditions. It is also recommended for use with hydrogen. Thanks to its versatility, it is used across many industrial sectors – from energy and chemical industries to mechanical engineering, food processing, and transportation technologies.

A Modern Material for Reliable Sealing

The AFG-300 UT® gasket sheet belongs to gasket materials produced by compressing fiber-based compounds. Its base consists of a combination of special fibers and a rubber binder that ensures an optimal balance between strength, flexibility, and chemical resistance. Special fibers provide the material with high mechanical strength and dimensional stability, which is particularly important under long-term loads in flange connections.

The rubber binder improves resistance to oils, fuels, lubricants, and various chemicals commonly present in industrial environments. As a result, this sealing material maintains its properties even under fluctuations in pressure and temperature. It is also easy to process and suitable for manufacturing precise gaskets for various types of equipment.

The AFG-300 UT® gasket sheet also features a specially treated anti-stick surface, which prevents the material from sticking to flanges and simplifies both installation and removal of gaskets.

Main Advantages of the AFG-300 UT® Gasket Sheet

The new gasket sheet offers several benefits appreciated by designers, service teams, and plant operators:

✔ ANTI-STICK SURFACE – does not stick to flanges – enabling easier flange disassembly
✔ FLEXIBILITY – more flexible during installation
✔ GAS TIGHTNESS – recommended for hydrogen applications
✔ AVAILABILITY – large stock availability
✔ EFFICIENCY – cost-effective solution

The AFG-300 UT® gasket sheet is a universal sealing material with high chemical resistance to a wide range of media, including oils, fuels, and technical gases, including hydrogen. Thanks to stable thermo-mechanical properties, good compressibility, and the ability to adapt to sealing surface irregularities, it ensures reliable and long-term sealing even under combined pressure, temperature, and chemical exposure.

Operating Properties and Reliability in Practice

Key operating parameters include:

• short-term temperature resistance: −50 °C to +360 °C
• maximum continuous temperature: +260 °C
• maximum temperature with steam: +220 °C
• maximum pressure: 110 bar

The AFG-300 UT® gasket sheet is designed to perform reliably even in demanding operating environments. The material retains good mechanical properties at elevated temperatures and pressures while providing the flexibility required for effective sealing of flange joints.

Thanks to its construction, it effectively compensates for minor irregularities on sealing surfaces, minimizing the risk of media leakage. The material is also resistant to vibrations and dynamic loads commonly found in pumps, compressors, and piping systems. These properties make the AFG-300 UT® gasket sheet a reliable material for long-term operation in applications where safety and sealing system stability are critical.

Certifications and Approvals for Demanding Applications

The AFG-300 UT® gasket sheet holds a wide range of international certifications enabling its use in demanding or regulated applications:

• DVGW – gas and water applications
• WRAS – drinking water systems
• TA-Luft – emission requirements for flange connections
• BAM – oxygen service applications
• EC 1935/2004 – materials suitable for food contact
• Germanischer Lloyd and ABS – marine applications

These approvals are often decisive when selecting sealing materials for critical technological processes.

Applications Across Various Industrial Sectors

The AFG-300 UT® gasket sheet is mainly used for manufacturing flat gaskets for pipelines, valves, pumps, compressors, and technological equipment. It is widely used in industries such as:

• energy industry
• chemical and petrochemical industry
• mechanical engineering
• food industry
• transportation technologies

The material is suitable for systems handling media such as water, steam, oils, fuels, gases, and technical liquids. Due to its high gas tightness, it is also suitable for gas systems including hydrogen applications, where extremely high sealing performance is required.
