Product Description

Around 1988, Volvo started using chemical gasket sealant in place of many gaskets in a variety of places on engine and drive train parts. Later models use it almost exclusively (paper style gaskets aren't available for many parts.)

This is an anaerobic sealer just like the factory Volvo sealer.

Use on (aluminum) oil pans, camshaft covers, timing covers, etc.  Anywhere that you are mating two flat machined surfaces together.

It is ideal for sealing torsion-resistant metal parts that have flat surfaces. 

Use by applying a thin, even film to the flat surfaces being mated and bolt/attach together.

*Please note: depending on the specific job you're doing you may need 2 tubes, or the larger bottle of Genuine Volvo or Victor-Reinz gasket maker in suggested products below. For example replacing a head on a whiteblock will typically require 2 bottles. 

Additional Technical Information

This anaerobic sealant does not require oxygen to cure, and is pressure-activated when squeezed between two flat metal surfaces. Do not use between a surface and a rubber, paper, or cork gasket, such as with water pump, valve cover, or oil pan gaskets; if there's a gasket between the mating surfaces, use silicone RTV instead.

About Mahle

Mahle has been manufacturing high quality products since 1920.  Mahle is one of the largest manufacturer of filtration products in the world.  Many OEMs including Volvo use Mahle for many of their OE products.  For example, in many cases, the filter you buy in a blue Volvo box will have Mahle branding on it.  Mahle offers the same quality products to the aftermarket that is does to the OEMs.  In addition to filtration, Mahle also produces engine parts such as pistons and engine gasket sets.  Mahle recently acquired Behr which expands their coverage in to other high quality products such as thermostats and heating and cooling system parts.
