bending fuel oil line

How do you bend coated fuel line? so far I gotten away with bending around a piece of pipe or a can etc. So I figured I would up my game and picked up a Kline roll bender "Klein-Tools-51006-3-in-1-Tubing-Bender"

The plastic gets beat up a bit and it just one radius.

    the groove needs to match the od of the tubing and coating. there are also internal and external bending springs. how many radii do you need? you just bend it until you get the angle of the new direction that you need.

    That's the kind of bender I use on small tubing. If you are having scuffing, try spraying the tubing with silicone spray before bending. Make sure the silicone spray is suitable for rubber and plastics, not all are.

    Unless you need a tight 90, bend it by hand, working it up and down the bend a little. Otherwise use the size bender for the outside diameter of the tubing with the jacket.

    "the groove needs to match the od of the tubing and coating." yes, but who makes this?

    refrigeration 1/2”.
    plenty of electrical lube

    Try not to slide the tool but walk it.

    a little bit bigger is probably ok. a little small is going to tear up the plastic which its probably just a cosmetic issue.

    you can also fill the part you want to bend with water and freeze it. it won't burst if it is a short section. both have issues with getting the line clean enough for fuel afterword.

    and you won't need a second mortgage for the r22 like Ed's method.

    I can't see using a bender on contained oil line ? A boot works in the corners ..

    For bright work I like ratchet type , looks like a cross bow . You would need try the larger size

    I use the 1/2" block to bend 3/8" coated oil line. I have this mostly for refrigerant piping.

    I have that set @HVACNUT but the bending forms are all black plastic like the clamp die. I like your pretty colors!

    After you make that expensive repair and you still have the same problem, What will you check next?

    @HVACNUT thanks, we have a bender like that for refrigerant in the "big/installation" van. Its awkward in tight spaces but good to know coated 3/8 oil line fits a refrigerant line Die>

    I know REMS , and maybe the other German benders have metric sized heads available. Measure the OD and see how it converts to metric sized

    Its only 3/8" I would just bend it by hand.

    i watched a video of someone using foam in a can without gloves the other day. there are lots of things that i don't wear gloves for and lot of other things i sometimes wear gloves for because it is easier than scrubbing my hands in gojo or paint thinner but latex or nitryl gloves are great for foam in a can because more or less nothing takes that stuff off.
