## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Works great on PVC, SS, and Brass
  

*by M***K on Reviewed in the United States on 27 October 2023*

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.

    Sealed with a kiss
  

*by K***E on Reviewed in Canada on 17 July 2021*

Used this to seal the annoying dripping threads on my shower head arm where Teflon tape wouldn’t seal. Worked perfectly

### ⭐⭐ 







  
  
    Receiving as almost empty pack !
  

*by V***I on Reviewed in Canada on 9 September 2019*

It was only less than one third full. It seems almost whole pack is empty.
