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.
