Very easy to apply. Keeps connections from leaking. Good quality. Performing very well. Definitely get value for your money, this will last any homeowner a lifetime.

Seals as intended. Brush isn’t very precision oriented, but works fine.

I installed a tankless water heater. It needs to be flushed at least once a year. There are 2 valves to install in the hot and cold water lines. One valve each. These have ports and gates in them so it makes it easy to hook short washing machine type hoses to a flushing kit. The kit is a 5 gallon bucket that comes with a sump pump and hoses. One hose hooks to the cold water side of the hot water heater and to the exit port on the sump pump. The pump sucks cleaning agent and water out of the bucket and into the hot water heater. The cleaning fluid exits the HW heater into the exit hose and back into the bucket. I run it for an hour. The aforementioned hookups have house water shutoff gates that isolate the cleaning system from the house system. Those gate hook to the house system had leaks in the connections until I used the Monster caned plumbers past and the Monster tape on the threads. I wrap the threads with 3 wraps of tape each. Professional plumbers use both and I now see why. No more leaks. The cleaning valve system remains in place so it is important that they don't leak. The tankless system is now set for another year. Very easy to flush the system every year now. Turn the house valves off, hook up the hoses to the flushing kit pump and bucket. Turn off the house valves. Turn on the flushing system valves. pour in the flushing liquid and a gallon of water. Plug in the pump and go get a cup of tea. Wait and hour. Do the above in reverse and look like a hero. No leaks. No mess. I recommend Monster tape and sealer.

Blue Monster is twice the price of the competition but you get what you pay for

Plumber friend says Blue Monster does the job. Having a tough time stopping a leak (pool 10-psi-pressure water) on new check valve (excellent price, but threads probably not cut rightly). Suspect threads on check valve (cpvc) are 2-inch National Pipe Straight. Trying to mate it with 2-inch NPT National Pipe Tapered male black polypropylene fittings. Bought check valve online (starts with a, ends with zon) product probably made youknowwhere-starts with c ends with hina. Good ball check, suspicious of threads. On 3rd try at assembly, used Blue Monster thread dope on male and female threads, with 5 wraps of Blue Monster tape over dope on male threads. Messy, but it works.

Used this product to seal threads between pvc and brass fittings. It’s thick! This is not a glue.

Great pool sealant
