Good result
Used on the thread of a plastic end of steel tap in kitchen. Spread over threads of both male and female threads. Allowed to cure for 24hrs and so far plastic end of tap is remaining in place whereas previously it would fall off with water force.

Great product thank you loctite
For sealing threaded joints between metal and plastic pipe fittings. There is nothing better and it's WRAS approved for when dealing with potable water. Simple perfect.
