577 Thread Sealant 50 mL Tube

Used this on a recent solar panel install on a van and so far have been quite happy. Seems to have sealed all of the rivets and bolts used in the install. Even in the blazing sun, have plenty of time to work with this stuff. Application is easy once you get the bottle open; you have to pull the nozzle away from the body to open it. There is some significant extra run off once you close it again, so take that into consideration when applying.

You have to shake it a lot to mix it if it's been sitting at all. I keep it in the refrigerator hoping that will preserve its shelf life which isn't listed as that long for a non-professional. I usually use teflon tape or the liquid teflon even more. However, you still need to max torque on the fittings and some of the Chinese SS & Brass fittings still leak. If you've got elbows or tees that need a particular alignment, best fitting torque often puts me 180-270 deg. out of alignment. This stuff works great to seal (I was using less than 80 psi) water fittings with a mild snug fit and yet without excess force, is removable. Leaves a lot to clean up on the threads but an easy job. Now my go-to sealant for pipe threads I would typically glue or solder or epoxy. Hope it stores well in the refrig.

product worked as expected though quite spendy

Great pipe thread sealant!

I've been fooling around with various tapes, teflons, sealants, puttys for years. Sometimes your leak free, but often you have a redo. This stuff has a chemical metamorphosis in the joint and doesn't allow a leak.

Used this to seal straight threads in a hydronic system. Held up to 100 psi of air no problems.

Some people were saying it’s a small size. This is gonna take me years to finish.No complaints

Purchased this product before and its great but order recently and received almost empty container and it was not sealed.
