Questions & Answers

can it be used on propane

Answer This Question

This product is specifically formulated for refrigerant lines. You would not use it on fuel lines. For propane, natural gas and oil I specifically use Gasoila brand pipe dope as it is particularly resistant to breaking down when exposed to solvents.

    I guess it worked well, I used it on a mini split install and had no leaks.
