Metal Eyelet Flat Gaskets

Metal Eyeleted Flat Gaskets
The metal eyeleted flat gaskets offer special protection against blowout for the sealing of critical or dangerous media. The sealing insert is usually made from Flexible Graphite material.
Cut gasket with and without metal eyelet

The simple flat gasket cut from sheet material remains the most widely used method of flange sealing. However, in today ‘s world of environmental awareness and the need for ever tighter control of emissions, those gaskets may not meet all the latest mandatory regulations. Wealson has met these ever increasing demands and laws regarding environmental and safety issues by developing a full range of gaskets reinforced with metal eyelets.

The standard metal jacket is formed with an austenitic stainless steel leaf with a thickness of 0.15 – 0.2 mm U-shaped and pressed in such a way that it becomes a single body with a base seal. The good malleability grade of the austenitic stainless steel gives to the covering excellent mechanical properties and good resistance to erosion, while the well know resistance to heat and to corrosion ensures the long working life of the seal.

Advantages of Metal Eyelet Flat Gaskets

	Blow out protection
	Protection against chemical attack
	Improved sealability due to the local higher stress under eyelet.
	Prime features of eyelets
	Reinforce the gasket surfaces.
	Erosion of expanded graphite material is prevented at high fluid velocities – which also eliminates possible graphite contamination of the fluid media – when eyelet is fitted to inside diameter.
	Blow-out potential is greatly reduced when eyelet is fitted to outside diameter.
	Reduced danger of overcompression at high seating stresses.
	Gasket is easier to handle.
