The best leak prevention on swimming pool fittings
Having tried using Loctite 55 on a swimming pool MPV and having the valve still leak at the threaded joints, I opted to try out this liquid sealant. I put the liquid on both the make and female joints and easily screwed them in by hand. I waited 24hr before I turned on the pump & when I did, there were no leaks from any of the joints. I’ve bought another tube as backup, I’ll be using this stuff instead of PTFE Tape and silicone from now on.

Zuverlässige und vielseitige Gewindedichtung
Anwendung: LOCTITE SI 5331 wird vor dem Zusammenschrauben der Rohrgewinde auf die Gewindegänge aufgetragen. Die Dichtmasse härtet bei Luftkontakt aus und bildet eine elastische Dichtung, die die Verbindung gegen Wasser, Gas und andere Medien abdichtet. Tipp: Für optimale Ergebnisse sollten die Gewinde sauber und trocken sein. Fazit: LOCTITE SI 5331 ist eine zuverlässige und vielseitige Gewindedichtung, die sich für eine Vielzahl von Anwendungen eignet. Sie ist einfach anzuwenden, dicht und sicher und bietet eine lange Lebensdauer. Empfehlung: Ich kann LOCTITE SI 5331 allen empfehlen, die eine sichere und dauerhafte Abdichtung von Rohrgewindeverbindungen suchen.
