Flare wrenches without inside bevel?

[bshusted]

I was replacing the front brake lines on my Audi yesterday and found that the fittings are mounted through a flat surface. Most flare wrenches that I have seen, including the Craftsman that I own, have a deep bevel inside before the hex portion. This meant that at best the actual flats were contacting 50% of of the fitting. Does anyone know where I can find a set of metric flare wrenches that are flat and have no inner bevel? Even the Snap-On ones seem to have the bevel. There are plenty of crows feet that are flat, but I haven't found any wrenches.

If the one you have is of decent quality, grind down the bevel so that there is only a very little left, to assist when using it.
Most brake fittings have the hex part proud of the brake part several mm´s.
Maybe mot a problem after all?

My older Macs are flat...like these:

I have a set of mac with a flare nut on one end and an open end on the other end that is smooth. If you google mac flare nut wrenckes and go to images you can see them.

I gave up on useing flare nut wrenches on bleeders esp on wheel cylinders that are reassessed. Ive found that 1/4 drive 6point semi deep sockets work better

Thanks! I've got a set of the MAC wrenches on order. They look exactly like what I'm looking for. I thought about grinding it down, but thought that there must be a better way. I agree on using the 6pt socket for breaking loose the bleeders, but not possible to get a socket on the line fittings.

This meant that at best the actual flats were contacting 50% of of the fitting. Even the Snap-On ones seem to have the bevel. There are plenty of crows feet that are flat, but I haven't found any wrenches.

So you think this minor bevel is 50% loss of contact? That bevel is to ease in using the wrench and the loss of a flat is so minor your will never notice it.

Bob, As I mentioned, the fitting goes through a hole and the hex portion of the fitting is at the surface. If the hex portion of the fitting is only 4mm tall and the bevel is 2mm deep, I think this presents a problem. Take your wrench in the picture and imagine trying to turn a low-profile nut resting on a table.

I'll see if I have time tonight to pull a wheel for you to check out what I'm talking about.

It seems if you're up against a flat surface, go flare nut crowsfoot for flatness.

If you're working in a bore, some brands of flare nut socket will tend to have less material surrounding the hex and allow deeper access. Also, the bevel will probably be a lot shallower than on a wrench. That may provide enough material contact to address everything you're wanting.
