NAPA Ploy Coated Line Flaring

Good morning HAMBers!

I have a quick question, since searching came up dry. I'm going to fab up a fuel line for my 61 GMC this weekend using that poly-coated brake line from NAPA.

My question is: do you have to remove the poly-coat from the end that's going to get flared? If so, how would you remove it? I was thinking a quick pass on my wire wheel would do the trick. Also, would the poly coat allow it to slip in the flare tool?

Thanks!

 

with a good flaring tool you dont need to remove it.

 

I usually clean the area where the flare is going to be. never had a problem with it slipping in the tool.just wire wheel about a 1/2 inch

 

I have the Eastwood one. Cost a pretty penny, but it rules!!!

Cool, will do. Thanks!!!

 

just flare it with a quality tool it will be fine.

 

Ditto. Cut and flared some a couple of days ago. Worked fine. Nobody asked, but I just can't get used to seeing a coating other than zinc on brake line tubing. Maybe that's just me.

I'll just give it a quick touch on the wire wheel.

My first thought was that the poly coat would have a "gasket" effect on the sealing surface, but over time it could suffer from creep effect and cause a leak. I'll feel better with steel-steel sealing surface contact.

Thanks again guys!

 

never had one leak because of the coating on the flare. I have had them leak because some incompetent ass running the flaring tool.

I work alone...............

 

Never had any problems flaring or with leaks after flaring them on any size line.

 

Alright, looks like I'm going to just cut & flare without screwing with the coating. If it leaks, I'll kiss it on the wire wheel.

Thanks again for the replies!
