Shall I use this for air circuit breaker fixed and moving contact
July 6, 2018
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.

Q: The Dow Corning DC-4 Compound used for oil filter gaskets? Part # 09-27700
Yes, Dow Corning DC-4 is commonly on the rubber gasket on an oil filter for a new installation.
Q: Can you use DC-4 on o rings used in avgas fuel systems?
It is not recommended. Parker O-Lube, our p/n 05-00773 would be a better choice.
Q: What size is this Dow Corning DC-4 compound in ounces?
Part # 09-27700 is priced and sold as a 5.3 oz tube.
Q: Can I use DC-4 on hydraulic brake master cylinder o-rings that use the red milspec hydraulic fluid?
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.
Q: May the DOW Corning DC-4 be used on silicone rocker arm cover gaskets to aid in sealing?
It is most commonly used as a dielectric grease, we do not believe it would be the correct material for that application.
Q: Can this DOW CORNING #4 be used on Engine Spark Plug wires at the spark plug and at the Distributor Cap?
Yes but you would want to look at your maintenance manual to see if it is called for.
