These are awful, spend a couple of pound extra and buy the metal ones. We bought these to do the final drain tests on a project and they failed miserably. They just don't seal the pipes at all, so we've been out and bought the metal version and had no problems. Complete waste of money.

No funciona muy bien. Cuando aprietas un poco para sellar la tubería se desmonta.
