Metal gaskets

Extreme tightness in critical conditions

Definition and main characteristics

The metal gaskets are sealing elements made entirely of metal, designed to work in the following conditions extreme conditions of pressure, vacuum and temperature. Unlike elastomeric seals, metallic seals offer a higher superior resistance against deformation, corrosion and fatigue, making them the ideal solution for applications where reliability is critical.

Key features of metal gaskets

Suitable for high pressures.
Efficient operation in a very wide temperature range, from cryogenic applications to environments of more than 1,000 ºC.
Compatible with aggressive chemical environments and gaseous media.
Designed to achieve the metal-to-metal contact, to ensure the required level of watertightness.
Available in multiple geometries, materials and coatings.

Sealing solutions for demanding environments

At Epidor, we offer metal gaskets specifically designed for static sealing in extreme conditions, where conventional elastomer gaskets cannot guarantee a reliable seal. These gaskets are suitable for use in environments of:

High pressure
Extreme temperatures (high or cryogenic)
Ultra high vacuum

They are especially used in sectors such as energy, chemical industry, cryogenic sector, and applications where safety and sealing reliability are critical.

Types of metal gaskets available from Epidor

At Epidor, We have different variants of metal gaskets, each one adapted to specific sealing needs:

Annular metal gaskets (RTJ)

Designs with circular sections, oval, octagonal with or without compensating hole.
High mechanical resistance.
Requieren very precise and complex assemblies.

Corrugated metal gaskets

Flat gaskets with slight undulations or corrugations.
Contact metal-metal between the corrugations and the flange faces.
Revoseal Revolutioncombination of a corrugated gasket profile and a flexible filler material to achieve a triple sealed effective.

Hollow metal gaskets

Sections circular or special (as type C).
Inside they may contain a pressurized gas or a spring (energized).
The ideal solution when a high elasticity combined with high tightness.

Materials and finishes available

In order to guarantee resistance in aggressive environments and extend the life of the part, our metal gaskets can be manufactured in:

Stainless steels of various grades
Nickel-based alloys (Hastelloy, Inconel, Incoloy)
Other materials such as Elgiloy®, aluminum, tantalum, etc...

We can also apply surface coatings as:

Gold, silver, copper, tin, nickel or PTFE depending on the application.

All our gaskets are manufactured with specific surface finishes, adapted to the type of application and the level of demand of the environment.

FAQ's about metal gaskets

When should I use a metal gasket?

When the application requires working with high pressures, extreme temperatures or vacuum, and elastomers are not suitable.

What is the difference between a solid and a hollow gasket?

Solid gaskets are stronger and require higher tightening. Hollow gaskets are more elastic, require less tightening and can be energized to improve sealing.

Can I order a custom metal gasket?

Yes, in Epidor We design customized metal gaskets according to the pressure, temperature, geometry and chemical compatibility requirements of each application.
