When installing LPG valves on a gas tank<\/strong>, a reliable thread sealant<\/strong> is essential.
We are often asked: Is Loctite 55 suitable?<\/em> Or: What do you use at LPG Techniek Van Meenen?<\/em><\/p>\n\n\n\n

Let us clarify.<\/p>\n\n\n\n

What do we use?<\/h3>\n\n\n\n

For sealing threads on LPG tanks, we use a professional anaerobic liquid sealant from Berner<\/strong>.
\ud83d\udc49 It cures in contact with metal and in the absence of oxygen, creating a gas-tight and vibration-resistant<\/strong> connection.<\/p>\n\n\n\n

Loctite alternative?<\/h3>\n\n\n\n

A comparable product from Loctite is Loctite 577<\/strong>.
\ud83d\udc49 This is also an anaerobic liquid sealant<\/strong>, specially designed for metal threads in gas and fluid systems.<\/p>\n\n\n\n

And Loctite 55?<\/h3>\n\n\n\n

Loctite 55<\/strong>, a Teflon sealing cord<\/strong>, is also approved for LPG applications<\/strong>.
It is wrapped mechanically around the thread and provides a solid seal.
\ud83d\udc49 However, for permanent installation<\/strong> of LPG valves, we prefer a liquid sealant like Berner 4270 or Loctite 577<\/strong>, because it cures and offers better resistance to vibrations and temperature changes<\/strong>.<\/p>\n\n\n\n
