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.

I live in Canada which makes getting parts more difficult due to shipping and availability. I decided to try late model restoration out as they are Canada shipping friendly. The order went smoothly and the parts arrived, and were exactly as i expected. Then a problem arose with one item. Now being in Canada this usually makes this a very painful experience to deal with due to the cost of shipping products back and forth across the border. Most of the time it is just easier and cheaper to just order a new one and cut the loses. Not in this case. I sent out an email with the issue and by the time I went outside to take a picture i already had a response. A new product was shipped out immediately. I could not believe how good the customer service was. This will be where i will get what i need for now on. Anyone can sell a product but it is nice to have a company stand behind what they sell. Thanks again.
