Seals

A seal may seem like a small part of your installation, but its impact on safety, emissions, and operational reliability is significant. The right choice of seal prevents leaks, unplanned downtime, and unnecessary maintenance costs.

At KLINGER Belgium, you choose certainty. We work with high-quality sealing materials such as KLINGER Top-Sil ML1, KLINGER QUANTUM, and KLINGER TOPCHEM, combined with in-depth technical expertise. Thanks to our wide range, in-house cutting and production workshop and +130 years in sealing technology, we support customers in almost every industrial sector.

Our industrial seals

 

KLINGER Belgium supplies a complete range of industrial seals for both standard applications and the most critical process conditions.

 

1. Rubber seals

Rubber seals are used in drinking water installations, gas networks, HVAC systems, and general industrial applications. . Thanks to their high flexibility and good compression properties, they provide a reliable solution for low to medium pressure applications.

Available in various elastomers, including:

• NBR
• EPDM
• FKM (Viton®)
• Hypalon® / CSM
• silicone
• special compounds for drinking water, gas, and industrial applications

Suitable for applications where flexibility, easy assembly, and chemical compatibility are central.

 

2. Soft fiber gaskets

Rubber-bonded fiber materials remain one of the most versatile sealing solutions in the industry.

Our range includes, among others:

• KLINGER top-sil ML1
• KLINGER Quantum
• Klingersil C4400
• Klingersil C4430plus

These materials combine:

• high mechanical strength
• excellent leak-tightness
• good chemical resistance
• reliable performance under varying loads

They are widely used in general industry, utilities, OEM, and process installations.

 

3. PTFE seals

For highly chemically aggressive media, PTFE offers exceptional chemical resistance across a very wide range of applications.

Our offering includes:

• virgin PTFE
• expanded PTFE
• KLINGER top-chem high-performance PTFE materials
• PTFE tape and custom sealing solutions

PTFE seals are particularly suitable for:

• acids
• alkalis
• solvents
• oxidative chemicals
• pharma
• food
• ultrapure processes

When chemical compatibility is decisive, PTFE is often the safest choice.

 

4. Graphite gaskets

Graphite gaskets are designed for applications where high temperature, steam, and low emissions are central. Due to their excellent thermal stability and strong compression/recovery properties, they offer a reliable seal under heavy thermal loads. They are used in power plants, petrochemical installations and other processes where low emissions and high thermal stability are required.

 

5. Semi-metallic gaskets

 

When higher pressure, temperature, or mechanical load require extra structural strength, semi-metallic gaskets offer an excellent solution.

Our range includes:

• spiral wound gaskets
• kammprofile gaskets
• corrugated gaskets
• metal jacketed gaskets
• engineered multilayer sealing concepts

These solutions combine:

• high mechanical strength
• excellent leak-tightness
• high blow-out resistance
• low emissions
• high temperature resistance
• reliable performance under thermal cycles and flange rotation

Many applications comply with TA-Luft, Fire Safe and feature EN 13555 gasket parameters.

 

6. Metal seals

For extreme process conditions where maximum mechanical strength and absolute sealing certainty are required, KLINGER offers fully metallic sealing solutions.

Including:

• RTJ (Ring Type Joints)
• oval and octagonal ring joints
• lens rings
• weld ring / seal solutions

These are used in:

• offshore
• high-pressure gas systems
• refining
• petrochemical high-pressure installations
• critical safety applications

 

7. Gland packings

Braided gland packings are used for sealing pumps, valves, and rotating applications. They are suitable for static and dynamic applications, at varying temperatures, pressures, and media.

Available in various constructions based on:

• graphite
• PTFE
• aramid
• carbon
• hybrid fibers

Always selected based on medium, temperature, pressure, and movement profile.
