The item received properly packed.
DC-4 has so many uses from electrical to lubing oil filter seals. Great product.
Shall I use this for air circuit breaker fixed and moving contact
The best grease that I have ever found to coat spin on oil filter gaskets. They absolutely will not seize on to the housing when is greece is applied to the gasket surface.

Yes, Dow Corning DC-4 is commonly on the rubber gasket on an oil filter for a new installation.
It is not recommended. Parker O-Lube, our p/n 05-00773 would be a better choice.
Part # 09-27700 is priced and sold as a 5.3 oz tube.
A silicone base grease is recommended for o-rings in brake systems. We offer Dow Corning 55, our p/n 08-13684, which is listed in Cleveland's maintenance manual to lubricate cylinder o-rings. The information I found on DC4 does not indicate it can be used for hydraulic systems.
It is most commonly used as a dielectric grease, we do not believe it would be the correct material for that application.
Yes but you would want to look at your maintenance manual to see if it is called for.
Molykote 4 is used as a replacement for DC-4. We have added the TDS to the web page which lists the referntial specs that are available.
