    Flare fittings

    Curious about what you guys think. We see it more in refrigeration than AC, so do you guys use the sweat adapters, that is a flare nut premade that you sweat on, do you flare, or do you double-flare? I use the adaptors under certain circumstancesa) Too lazy to get the flare kit out or (b) tight spaces
    I can't remember the last time I made a flare that was NOT a double flare. Don't trust a single flare..made by me anyway...

    use the yellow jacket tool.. never used a flaring block since.. only time a flare leaks for me just just tighten it abit.

    ive seen the sweat on adapters (tubing with a flare on it) im sure it would be nice if you needed a flare but didn't have the room to make one

    i live by the yellow jacket flareblock which swivels while flaring and CLICKS when the flare is done. for me dummy proof add a little oil then tighten , job done. for really tight spots then maybe ya the sweat type or take my chances on the a normal type flareblock

    The best flaring tool had a fluted cone

    But I forget the brand right now. Really excellent flares every time.

    I always run a swaging bit in until it juuuust bells the copper. Then I switch to the flaring cone. The feel of the cone lever changes when the flare is right. It kind of 'gives' a little.

    Flaring a dryer in eliminates cutting it out later.

    Think thats the Imperial one that I use PHM

    404 when I see the premade ones that's the first place I leak check

    The Y/J head is offset and rolls around the pipe instead of compressing the whole surface at one time like the others.

    Stupid question, what's a double flare?

    I'll use the premade sweat-on flares if I'm close to a parts house and know I'll need one beforehand, otherwise I use a flaring block.

    the adapters have a really strong point that i like and that is the flare, its extra thick and factory machined , almost impossible to overtighten , great and reliable time saver plus neat work and as stated much more practical for small driers, regards stan

    I use copper flare gaskets

    But only on brass-to-brass flares.

    What is the gain in using them inside a regular copper end-flare?

    Double flares are when you use the double flare tool and it 'bowls"(is that a term?? haha) the copper in ward then you put the 45 degree flare cone over in it which makes the flare twice as thick, so basically the flare seat has 2 layers of copper instead of one. When done properly they make nice joints.

    I like it because it makes the flare twice as thick and I feel like i get a better bond plus i dont know how to make a double flare with my flare yoke and block.

    IU can't say I agree with that, it's like saying using a washer makes a bolt thicker.

    a double flare makes the flare thicker, well the part that matters anyway
