Graphite gaskets
Graphite sheet gaskets are high-quality gaskets used in demanding industrial applications.
These gaskets consist of a combination of graphite and a metal carrier, usually sheet metal.
Graphite offers excellent sealing properties, is temperature-resistant and resistant to chemical influences.
The metal carrier gives the gasket additional mechanical strength and stability.
This makes graphite sheet metal gaskets particularly suitable for use in high-temperature environments and in areas where aggressive chemicals are present, such as in the petrochemical, power plant and chemical processing industries.
They ensure a reliable seal, even under extreme conditions, and contribute to the safety and efficiency of systems.
Our standard delivery program includes Sigraflex gaskets
– SIGRAFLEX® Universal
– SIGRAFLEX® UniversalPro
– SIGRAFLEX® High Pressure, HDpro
Graphite gaskets can also be supplied with inner and/or outer flanges
Standard/standard gaskets are available by overnight delivery service or 48h / 72h appointments!
Rubber-steel seals
Rubber-steel gaskets are robust and reliable sealing materials consisting of a combination of elastic rubber and solid steel.
This design combines the flexibility and adaptability of rubber with the strength and pressure resistance of steel, making it a preferred choice for many industrial applications.
The rubber component provides an effective seal by adapting to uneven surfaces and compensating for vibration and movement.
The steel core also provides the gasket with the necessary structural strength and prevents excessive deformation or failure under high pressure conditions.
Rubber-steel gaskets are often used in the automotive, mechanical engineering and oil and gas industries.
Our standard product range includes the following elastomer materials
- NBR
- EPDM (drinking water compliant)
- FKM
Standard/standard gaskets are available by overnight delivery service or 48h / 72h appointments!
Comb profile gaskets
Comb profile gaskets are high-quality gaskets that have been specially developed for demanding applications in the chemical, petrochemical and power generation industries.
They consist of a metallic base body with concentric combs and a soft sealing layer made of materials such as graphite, PTFE or mica.
This combination enables the gasket to withstand high pressures and temperatures as well as chemical attack.
One of the main advantages of the comb profile gasket is its excellent adaptability to unevenness and surface roughness of the flanges, resulting in an extremely reliable seal.
Our range of comb profile gaskets includes the following materials
Our range of comb profile gaskets includes the following materials
- Base body made of 1.4301, 1.4404, 1.4541, 1.4571, 1.5415 or soft iron

Lens seals
Lens seals, also known as sealing lenses or high-pressure lenses, are fully metallic turned seals which, thanks to their special shape, are protected against overloads as the sealing surface increases under heavy loads.
This means that the surface pressure only increases at a disproportionately low rate.
Lens seals are used in high-pressure areas, preferably in pipelines.
- Standard materials: 1.0460, 1.0352, 1.4571, 1.4541

O-rings DIN 3771 Form N ISO 3601
O-rings are closed ring seals with a round cross-section and are made of elastomers and plastics (FKM, EPDM, NBR, SILICONE, FFKM, PTFE, PEEK, PUR).
O-rings can be used to seal axially and/or radially.
The sealing effect is achieved by the elastic deformation of its cross-section.
ITS GmbH offers O-rings in the versions “molded” and “vulcanized together”.
- Version A: molded – DIN 3771 Form N
Tolerances according to EN: DIN ISO 3601-1 - Version B: vulcanized together – for static operating conditions

O-rings FFKM
Highest elastomer class | Highest chemical resistance
FFKM O-rings are elastomer seals made from the high-performance material perfluoro rubber (known as FFKM or abbreviated as FFPM).
This material combines the elasticity and sealing force of a pure elastomer with the chemical resistance of PTFE.
Due to their special material properties, FFKM O-rings are primarily used in the chemical industry, semiconductor industry, vacuum technology, bioanalytics, oil and gas industry and also in the food industry, cosmetics and pharmaceuticals.
O-rings made of FFKM meet the highest requirements for sealing performance and at the same time offer exceptional chemical resistance and thermal stability.
FFKM O-rings are resistant to almost all chemicals and can be used at temperatures of up to + 330 °C (depending on the type of FFKM used).
FFPM is primarily used in critical areas with extreme conditions where other materials are no longer fit for purpose after a short time.
Where conventional materials fail, perfluoroelastomers (FFKM/FFPM) are the most cost-effective and reliable long-term solution.
The advantages of FFKM O-rings at a glance
- Highest chemical resistance of all elastomer materials
- High temperature resistant up to +330 °C, depending on the FFKM type used
- Operating temperature -15 to + 330°C (special FFKM types also from -45°C)
- Resistant to hot water and steam
- Optimum vacuum behavior
- Very low compression set
- Fulfillment of high safety and cleanliness requirements
- Application-oriented and available in many different types
- Different approvals available
Our product range includes a wide range of FFKM types, depending on the individual application.
We supply FFKM O-rings with FDA or USP VI approval and Norsok M 710 / NACE 0207 conformity.
Good to know!
FFKM was launched on the market under the brand name Kalrez® by the company DuPont.
However, the latest generation of materials are at least comparable to the original Kalrez® materials.
In the meantime, other manufacturers (brands) have established themselves on the market alongside Kalrez®.
Kalrez® is a registered trademark of DuPont Dow Elastomers

PTFE seals
Polytetrafluoroethylene (PTFE) gaskets are versatile and high-performance sealing materials that are widely used due to their outstanding chemical resistance, high temperature resistance and excellent sliding and non-stick properties.
PTFE, known by the brand name Teflon, is a fluorinated polymer used in a wide range of industrial applications.
PTFE seals are inert to almost all chemicals and are highly resistant to solvents, acids and bases, making them ideal for use in aggressive chemical environments.
They can withstand temperatures from -200 °C to +260 °C without losing their physical properties and are therefore also suitable for extreme temperature conditions.
Our standard delivery program includes the following PTFE material:
- Gylon (3501,3504,3510)
- Dyneon (TFM4105)
- Klingertopchem (2003,2005,2006)

Spiral wound gaskets
Spiral wound gaskets are high-performance gaskets that are often used in demanding applications, such as in the chemical industry, petrochemical industry and power plants.
They consist of a metallic spiral winding combined with a flexible filler material such as graphite, PTFE or mica.
This design enables the seal to withstand high temperatures, pressures and chemical influences.
A key advantage of spiral wound gaskets is their ability to adapt to unevenness in the sealing surfaces, ensuring an excellent seal.
They are particularly suitable for applications where extreme conditions prevail, such as flange connections in piping systems or the sealing of valves and pumps.
Thanks to their robust design and versatility, spiral wound gaskets offer a reliable and durable solution for a wide range of industrial sealing requirements.

Corrugated ring seals
Shaft seals, also known as oil seals, are a special type of seal used in machines and systems to seal rotating shafts.
They prevent lubricants from escaping and dirt, dust and moisture from entering the machine components.
These seals are typically made of an elastic material such as rubber or silicone and often have a reinforcing metal reinforcement.
A key component is the sealing lip, which lies closely against the shaft and forms an effective seal due to the contact pressure.
