Multi-layer steel (MLS) cylinder-head gaskets – innovative sealing solutions for new engine designs.

Increasing torque and performance with decreasing consumption and emissions. The development goals in engine construction determine the requirements of modern gasket systems. As a leader in technology, an original equipment manufacturer transfers all of his expertise, experience and quality into the replacement parts business. With a broad product palette, Glaser^® supplies cylinder head gaskets for all conventional passenger car and commercial vehicle engines.

Cylinder-head bolts

Cylinder-head bolts guarantee a secure and releasable joint. However, this does not mean that the same bolt can be reused for the same application. When reassembling a cylinder head, always make sure to use new head bolts. The result will be a high sealing pressure for a reliable and tight joint.

Make sure to use head bolts exclusively from quality manufacturers. Glaser^® cylinder-head bolts comply with all manufacturer specifications, and are matched perfectly to our head gasket sets. Of course, the torquing guidelines are always supplied – available in 12 languages.

Oil seals

The most important types of dynamic seals are oil seals for use on rotating shafts, and valve stem seals for reducing the flow of oil through the cylinder-head into the combustion chamber.
In addition to simple oil seals and integrated radial oil seals, Glaser^® offers a new generation of PTFE radial oil seals.

Valve stem seals

As with shaft seals, Glaser^® offers the entire line of valve stem seals from single valve stem seals designed as sleeves in a wide range of materials to integrated valve stem seals. With this design, the seal and valve spring seat are combined into a single component. After installation, the valve stem seal is easily and securely fixed in the engine by the valve spring.

Valve Cover Gaskets

Cylinder head cover gaskets withstand high and low temperatures to provide a reliable seal with minimal tightening. Dana only uses high-quality rubbers to satisfy the tough demands.

Cylinder head cover gaskets are increasingly produced with profiles and not flat; that is, the gasket surface is provided with beads or lips. Now, instead of the entire gasket surface, only the profile needs to be pressed, that is, the sealing bead or sealing lip, and just a slight amount of bolting force produces sufficient deformation and adaptation.

Manifold Gaskets

Modern sealing systems have to deal with more aggressive media, higher temperatures, lower component strength and higher deformation under mechanical stress. This is why primarily elastomer gaskets made of high quality rubber are used in the intake area.
