Product illustrationFlat Metal Gasket
Made entirely of metal, for joints that call for a metal seal
A flat metal gasket is made from a single metal or alloy, typically as a flat ring or a custom profile. It relies on high contact stress and well-matched flange surfaces to form a seal. It is intended for specific joints where soft gaskets cannot meet the structural, temperature, or chemical compatibility requirements.
- Solid metalDimensionally stable and resists extrusion
- Made to drawingShape, thickness and tolerances as drawn
- Flange requirementsNeeds good sealing faces and sufficient seating load
Features
- Solid metal construction provides dimensional stability and resistance to extrusion.
- Profiles and dimensions are manufactured to equipment drawings, with thickness and tolerances controlled to the specified requirements.
- A range of materials is available to suit particular media and temperatures.
- Surface finish, machining tolerances and material condition selected for the equipment; soft covering layers available as a separate configuration.
Materials & configurations
| Component / Item | Material Options and Specification Details |
|---|---|
| Gasket body — common materials | Soft iron, carbon steel, stainless steel, and copper |

| Material and design specification | Grade, material condition, hardness, thickness and surface finish selected for the required sealing load |
| Configurations | Ring, full-face, and custom-profile gaskets made to customer requirements |
| Key properties | Material hardness, thickness, flatness, surface condition, and edge quality |
Standards & supply options
- Made to equipment drawings, with selectable material hardness, dimensions, thickness, tolerances and surface condition.
Typical applications
- Flange joints in high-temperature equipment, special chemical service, or applications requiring high contact stress.
- Metal sealing locations in machinery, valves, pumps, and pressure components.
- Industrial components requiring custom profiles, thicknesses, or materials.
Selection & service notes
Suited to joints that sustain the required contact stress. Flat metal gaskets have relatively low compressibility; selection includes chemical compatibility, flange flatness, surface finish, rigidity and bolt load.
Dimensions & specifications
Detailed specification tables are being prepared. Include dimensions, thickness, mating flange, materials and service conditions in your enquiry.
