Rated 4 out of 5 stars.
This Permatex PermaShield kit gives you two 2-ounce tubes of seriously tough gasket dressing and flange sealant.
It’s fuel resistant, so it’s perfect for engine work where gasoline or other fuels might come into contact with the seal.
Whether you’re reassembling a fuel pump, sealing a timing cover, or working on any flange that needs a reliable gasket, this stuff holds up.
It’s brand new and still in its original packaging, so you’re getting fresh sealant that hasn’t dried out.
The part number is 85420-Set2, which is basically a two-pack of the classic 85420 formula.
It’s easy to apply—just squeeze, spread, and assemble.
It stays flexible, so it handles vibration and thermal expansion without cracking.
Plus, it’s Permatex, so you know it’s trusted by mechanics and DIYers alike.
Great to have in your toolbox for those unexpected leaks or when you’re doing a full gasket replacement.
The 4-ounce total quantity means you’ve got enough for multiple jobs or one bigger project.
Fuel systems can be tricky, so using a sealant specifically designed to resist fuel breakdown is a smart move.
Keep a set around for peace of mind—you never know when you’ll need to patch something up or do a full reseal.
