How to Choose Klingerit® and Klingersil® Gaskets According to Industrial Standards (EN, DIN, ASME)

When selecting industrial gaskets, it is not only the composition that matters but also compliance with international standards. Engineers and maintenance managers need to ensure that every gasket installed meets the requirements for safety, tightness, and chemical compatibility.
In this article, we explain the regulatory contexts where Klingerit® and Klingersil® gaskets are accepted or mandatory, and which certifications support their use in highly regulated industries.

Klingerit® Gaskets: Tradition and Applicable Standards

Klingerit® gaskets (based on fibers and rubber) have historically been used in demanding thermal and mechanical applications.

• Applicable standards: mainly DIN and EN standards for flanges and fittings, especially in steam and pressurized fluid systems.

• Current limitations: due to environmental restrictions (mineral fibers), their use has been gradually replaced by modern materials such as Klingersil®, except in older facilities or where the regulation still allows it.

• Context: still used in plants where a full replacement of installations is not feasible and where compatibility with older DIN standards is required.

Klingersil® Gaskets: The Current Compliance Standard

Klingersil® gaskets, made from synthetic fibers and high-performance rubber, represent the evolution of Klingerit® and comply with a broad range of international regulations:

• EN 13555: defines chemical resistance and tightness parameters for flange gaskets.

• TA Luft / VDI 2440: German leakage certification, mandatory in chemical and petrochemical industries to ensure low fugitive emissions.

• API / ASME: compliance with American standards for flanges in pressure and temperature applications.

• DIN / EN 1514: standardized dimensions and tolerances for flat gaskets.

These certifications make Klingersil® the preferred option in:

• Chemical and petrochemical plants.

• High-pressure steam and gas installations.

• Sectors where compliance with strict safety and environmental regulations is essential.

Conclusion: Compliance as the Key Selection Criterion

When choosing between Klingerit® and Klingersil® gaskets, the key factor is not only mechanical or chemical resistance but also compliance with the required standards.

• Klingerit® still has a place in legacy installations governed by older regulations or in specific replacements.

• Klingersil®, on the other hand, ensures compatibility with current European and American standards, making it the recommended choice for new projects and highly regulated industries.

Rubber gaskets are critical components in ensuring airtight sealing in industrial HVAC systems. Over time, they can degrade due to heat, chemicals or pressure. A single worn gasket can lead to system failure or downtime, so regular maintenance is essential.

Here’s a practical 10-point checklist to help you inspect and maintain rubber gaskets effectively.

10-step checklist for rubber gasket maintenance

Step	Recommended action	Suggested frequency
1	Check for cracks or surface hardening	Quarterly
2	Look for swelling or deformation	Quarterly
3	Ensure mating surfaces are clean	Each inspection
4	Review pressure rating and chemical compatibility	Annually or after changes
5	Apply compatible grease if needed	As required
6	Replace any visibly worn or stiff gaskets	Immediately
7	Confirm resistance to temperature and humidity	Each audit
8	Store spare gaskets in dry, dark conditions	Ongoing
9	Log gasket lifespan for each application	Continuously
10	Contact supplier for custom parts or doubts	Whenever needed

Thermiculite®: The Sealing Material for High-Temperature and Critical Industrial Applications

Thermiculite® is an advanced gasket material known for its outstanding performance in extreme temperature and pressure conditions. At Manufactures Cusell, we use it to produce high-performance gaskets for demanding sectors such as petrochemical, nuclear, and automotive industries.

What is Thermiculite®?

Thermiculite® is a mineral-based mica material enhanced through a patented process by Flexitallic. It is an asbestos-free sealing solution, designed as a superior alternative to graphite, especially in oxidizing and high-temperature environments.

Key advantages of Thermiculite®

• Withstands temperatures up to 1000 °C without degradation.

• Excellent chemical and oxidation resistance.

• Performs well under high pressures and thermal cycling.

• Asbestos-free and compliant with strict environmental standards.

• High compressibility and recovery for effective sealing.

• Long-term stability, even in steam or hot gas applications.

Common applications

• Petrochemical industry: heat exchanger, flange, and valve gaskets.

• Power generation and nuclear: sealing components in reactors and turbines.

• Automotive and engines: exhaust and manifold gaskets.

• Pharmaceutical and food sectors: ideal for steam cleaning and hygiene requirements.

Thermiculite® vs Graphite

Unlike graphite, Thermiculite® does not oxidize or break down under high temperatures in the presence of oxygen. This makes it a superior choice for sealing in oxidizing atmospheres and applications where durability is critical.
