ARP 100-9904 Thread Sealer is a premium grade thread sealer that is designed for use on all wet deck cylinder block applications in order to prevent coolant leakage past the head bolt or head stud threads, while duplicating the recommended installation pre-loads associated with all ARP cylinder head bolts and studs. ARP thread sealer can also be used on pipe plugs, pipe fittings, fuel line fittings or any fitting that requires a flexible leak proof seal & is good up to 10,000 psi & -30° to 550°F. ARP thread sealer is designed for use on aluminum, steel, stainless steel and plastic materials against coolants, water, gasoline, oil, natural gas and LPG.
I bought this to coat the head bolts that run through the water jacket of the motor. Make sure you are using gloves and have cleaned the threads of any debris or oil. Cleaning is a snap. There is enough to build more than one motor. I am completely satisfied.
Yes, I would recommend this item to a friend!

I used this on my ARP head studs on the bolts that enter the water jacket. Its much thicker than the Permatex high temp thread sealant I usually use, thus providing a better seal.

Everytime I have delt with LateModel, it seems to get better and better. I have had all positive experiences which is much more than i can say about Summit, or American Muscle. I like the mom and pop shop feel i get when i deal with LateModel. We had a family buisness turning wrenches and a huge part of our success was customer service. Specifically treating every single female as how we would want our sister of mother treated when going to a buisness. We were always more than fair, accommodating and made sure to make all of our customers leave with a smile. And it worked. 30 years later my brother is still in buisness. Yesterday, I got that same type of treatment by Ian. Thank you Ian, you really went above and beyond like this was your personal buisness. Late Model, you just def locked in another lifelong customer thanks to Ian. Semper Fi
