Metal-Insert Gaskets
Industrial rubber gaskets reinforced with a metal insert, custom manufactured to technical drawing or sample, for high-pressure applications and intense mechanical loads where a plain rubber gasket would not hold up.
Technical Specifications
Indicative values for metal-insert gaskets. Exact parameters are determined according to the application and the dimensions in the technical drawing.
| Parameter | Value |
| Construction | Elastomer (NBR / EPDM / Silicone) + metal insert |
| Available insert materials | Carbon steel, stainless steel (AISI 304/316), brass |
| Maximum pressure | Up to 400 bar |
| Shape | Custom, to technical drawing |
| Metal insert certification | Inspection certificate per EN 10204 (type 2.2/3.1, on request) |
| Elastomer component testing | Per the standard of the chosen material (SR ISO 37, ISO 48-4) |
Applications
High-pressure hydraulic systems
Flanges, valves and shutoff devices subject to high pressures.
Heavy industrial machinery
Connections subject to intense mechanical loads.
High-demand equipment
Where a standard rubber gasket does not withstand pressure or the risk of blow-out under load.
Frequently Asked Questions
What is a metal-insert gasket and when is it needed?
It is a gasket made of a rubber layer (NBR, EPDM or silicone, chosen according to the application) reinforced with a metal insert — steel, stainless steel or brass — for high-pressure applications or intense mechanical loads, where a plain rubber gasket would not hold up.
What pressures can metal-insert gaskets withstand?
We formulate reinforced gaskets for pressures up to 400 bar, depending on geometry, thickness and the chosen insert material.
What metal insert materials are available?
Carbon steel, stainless steel (AISI 304/316) and brass. The choice depends on the working environment (corrosion, temperature) and the application requirements.
How do I choose the right elastomer for the metal insert?
Depending on the working environment: NBR for oil, EPDM for weathering/steam, silicone for extreme temperatures. We recommend the optimum combination based on the technical drawing and the application.
