Technical Poly-Armour PVF Coated Steel Brake Line

I have used Poly-Armour PVF Coated Steel Brake Lines before-but I do not think that I ever tried cutting and flaring it. I broke the handle off of my flaring cone, smashed my double flaring adaptor, and the clamp bar left extreme clamp marks. The flare itself is lopsided, I think it should seal without leaking (I will be the first to know if it leaks.) Can Poly-Armour PVF Coated Steel Brake Lines be flared, or do I need to go back to the older style steel brake lines?

 

The coating should be removed before flaring. Also, only flare on straight tubing, not bent or curved.

 

Not sure if You've heard of nicop, But it's a Lot easier to work with, an no rust...

 

Used it once cut the coating to flare; slid over inner glue coated heat shrink first. After installation cut the heat shrink for a tight fit to the nut. Looked nice and finished. A lot of trouble…

 

What kind of flaring tool were you attempting to use?

 

It’s normal steel so a standard flaring tool will work. An Eastwood type needs more bare tubing showing..

 

I recently fought with this stuff. Wasn't happy with any of the flares, using old school imperial bar clamp. Switched over to NiCop line and flared beautifully.
Not sure what steel they used in that coated line but it ****s for hand working.

 

This stuff didn't work well with my Old Forge hand flaring set, but flared nicely using a S.U.R.&R flaring tool. I'll never go back to the old flaring set after using the new tool...

 

I use good old plain brake line from NAPA, the new stuff has some green (anti rust?) coating, but flares well, no drama.

 

Not a fan at all! Even with my good RIGID flaring tool (one that can do stainless) I had trouble flaring that type. Slips through the block when you try to flare it. Removing the coating is an option, I guess, but defeats the purpose of using it!

 

Now it's time to put the flare nut on...

 

@warbird1 : are you using the vise mount (FT351) or handheld (HFT50) SUR&R?
I've heard there is a newer handheld that works damn good but haven't looked hard enough to find it...

 

@Beanscoot ... Forgetting the nut is traditional...

 

I hate the stuff , never had any luck trying to flare it . Ended up takin about someone’s Mom dealing with it .

 

?

 

Bought in 1989

 

I bought the same set at a garage sale ten years ago (however it was under a different brand name...probably the original manufacturer) for $10, it is less than perfect but I've used it to brake lines on four cars.

 

Looks like the Blackhawk tool I bought used back in '72. Used it for many stretch & shorten jobs on big trucks back when they still had juice brakes along with a many hot rods since. Worked good then and still does now.

 

I bought the vise mount tool. Cost a little bit of money, but was tired of fighting with the worn out Old Forge tool I've had for close to 50 years. Life is getting too short for me to waste time re-doing flares that look like **** and won't seal...
