Frequently Asked Questions (FAQs)
1. What is Fel-Pro karropak used for?
Fel-Pro karropak is a chemically-treated fibrous sheet packing used for sealing oil, water, and gasoline applications. It is designed to provide reliable sealing and is trusted by professionals in the aftermarket engine sealing industry.
2. Do you use sealant on Fel-Pro gaskets?
In most cases, Fel-Pro gaskets do not require the use of sealant. However, there are certain instances where sealant may be necessary, such as when mating gaskets or filling gaps. It is recommended to follow the specific instructions provided for each Fel-Pro gasket.
3. Do thicker gaskets seal better?
Thicker gaskets can provide a better seal by accommodating flange irregularities. However, they may also have drawbacks. Thicker gaskets are more susceptible to heat and may experience higher creep relaxation. It is important to consider the specific requirements of your application and consult the manufacturer's recommendations when selecting gasket thickness.
4. What is the strongest type of head gasket?
The strongest type of head gasket is a multi-layer steel (MLS) gasket. These gaskets are made of multiple layers of steel and offer excellent durability and sealing performance. However, they can be more challenging to install compared to other types of gaskets.
5. Should you use gasket sealer with gaskets?
Using gasket sealer can help reinforce the integrity and strength of the joint between gaskets and flanges. While a gasket alone may be sufficient in many cases, engineers often prefer to use sealant as an additional layer of protection.
6. Should I put silicone on my oil pan gasket?
It is recommended to use silicone at the mating points, especially in the corners, when installing an oil pan gasket. Silicone can help prevent leaks in sensitive areas and provide added sealing protection.
7. Do you use RTV with Fel Pro gaskets?
It is not recommended to use RTV (room temperature vulcanizing) sealant with Fel-Pro gaskets that have proprietary rubber or silicone sealing beads. RTV sealant can chemically degrade the rubber sealing beads and cause them to slip out of place, potentially leading to leaks. It is best to follow the manufacturer's instructions and use the recommended sealant, if necessary.
