Loctite Help

[Gen2Boost]

Hey guys. Hope all is well. Question for anyone that’s dealt with removing nuts installed with loctite. I need to replace the check valve hose on my Hornblasters spare tire delete horn kit mounted underneath my Gen 2. Steel braided hose runs from the compressor to the air tank. Both ends attached with a fixed hex nut and threaded in with loctite (picture attached). Is a blowtorch my best bet? I spent two hours at it today with hand tools and stopped as it would end with me stripping the Jesus out of the nuts. WD-40 didn’t do a thing. Should have been a quick swap which wasn’t quite what happened. Thanks in advance.

TBC: you mean the stainless fitting into the brass fitting? Brass one is teflon taped into the tank, right?

if so, Loctite blue should be all that ’s needed and it shouldn’t be that difficult. Red Loctite may need a little heat, but it shouldn’t need much at all. Purple, I understand is a bit more heat resistant.

Honestly, I’ve never had any Loctite resist me beyond hand tools, are those pics stock pictures, or actual from your truck?

I’d start with heat, but keep in mind you have brass in there which is going to expand at lower temp so don’t go too far. It looks like you have room to get a line wrench on the brass fitting, which might help.

Thanks! The attached picture is the hose that’s threaded in there where they used the loctite on both ends installed year and a half ago. I’ll try a small blowtorch carefully as Loctite recommends “localized heat and remove while hot”. The brass ones are indeed Teflon taped into the tank and they put loctite 545 onto the threading on the ends of the hose which on one end plumbs into the Teflon taped brass tank fittings while the other into the compressor. Also found a view videos suggesting brake cleaner as an option but I’ll have to look up if that’s corrosive as the valve is surrounded by the air lines for the actual horns. Thanks for the input. Will give it a go in the morning.

Did you loosen the swivel fitting first? Pipe fittings need pipe wrenches, just me though.

Yeah I’m thinking hardware store will be the first stop in the morning.

I would think a heat gun (HD hair dryer) would get hot enough to do whatever it is going to need.
If soaking them I would try acetone before WD-40 if taking any finish off of stuff in the area isn't a concern.

A micro torch will be sufficient heat after being applied for a approximately 30 seconds on a fitting like that if red loctite was used which is overkill IMO.

I work with loctite on a daily basis. Heat is about the only thing that works well. Especially on the green loctite !

Thanks guys! Heat indeed did the trick. Mini torch + locking pliers and both ends of the hose said fml and gave in. Owe you all a beer or stronger. Lmk when and where. Much appreciated
