Hi !

I'm hoping to improve my high-quality tool supply, and I'd appreciate your help.

What are the must-have sizes for flare wrenches for the 928?

So far, I've found fittings requiring 10mm, 16mm, and 19mm... but I'd like to set up a wish list of needed sizes...

It's interesting that most of the 'wrench sets' for sale have all but one of the three sizes above, they usually lack either the 10 or the 19 LOL

Thanks !

11mm Brake line fitting

15mm and 17mm along with 19 mm for fuel regulator/dampener removal/replacement

Got this GearWrench 6 wrench pivoting combo on Amazon. So far it has everything needed for $70. Two sizes per wrench, 9 - 11, 10 -12, 13 - 14, 15 - 17, 16 -18, 19 - 21. They work beautifully in light use so far.

Definitely!!! Most sets don't come with an 11mm. I had to get mine separately.

I'd just run the whole range from 5-high 20's.

Some of the A/C lines are pretty big.

I got lost, trying to figure out what fitting is 16mm on a 928....

Still lost.

I've never found a 16mm fitting on a 928 either.

Daniel, can you enlighten us, please?

Daniel5691

Sure ! At work now but will look at my list when I get home. If she lets me back in the house.

Me too.

Ooo. I need me a set of those. The 'ridged' flare wrenches I have are awkward for a couple of things.

Sorry for the delay, here is the information for the 16mm line fitting.
These are at the junction of the hard A/C line. I used a Williams combo wrench in one of the pictures, and then I threw on my calipers. There are 2 16mm fittings on this line.

My fittings look this gnarly because I paid a "welder" (LOL) 20 bucks to do the silver soldering for me for my new A/C flexible line replacement and this is what I got back. Along with my 20 dollars needless to say. Oh well, yet another job to re-repair. This gets old. Dan.

I see your confusion. Those ends are actually American sized "AN" fittings (which are 5/8" American wrench size) that someone silver soldered onto the German tubing.

16mm is very close to 5/8" and will work fine (actually a bit tighter than 16mm.)

I've never seen a 16mm fitting on a stock 928.

Porsche uses lots of both 16mm and 18mm wrench sizes, starting with the Boxsters and the 996 (or when the Japanese were hired to make Porsche more profitable and when Porsches turned into "plastic toasters".)

Note: For those who have not heard my "plastic toaster" analogy, here it is:

When I grew up in the late 50's and '60's, my family had this 2 slot toaster that sat near the kitchen table. It had incredibly thick and beautiful chrome. It had a round woolen cord, which rubbed through the outer cloth covering, every 10 years, or so, which needed to be replaced for safety's sake. Super simple. Chrome outer housing, heating coils, bake lite bottom with legs. One could turn a small rotary dial, which most likely controlled the current going directly to the heating coils, which made lighter or darker toast. Once properly adjusted, you never touched that rotary ****.
This toaster worked flawlessly every day...making perfect toast.

At some point in time, we needed a toaster with more "slots"....or wider "slots" needed to properly toast muffins or baggles, and of course....that culinary delight of the time...Eggos.

The chrome, wonderful, toaster was moved to a series of trailers and motorhomes, in the late '60's. Eventually, it found its way to a second vacation home.

I have no idea where it is, today....possibly hidden in a box in the top of my mom's garage (doubtful....she probably threw it out.)

Today, we have a plastic toaster. One year warranty. Doesn't matter the brand, they will last one year and a couple of months. Will never fail under warranty, but there is absolutely no way it will make it two years!

There's a zillion separate pieces. Impossible to fix, if they even sold the pieces (which they don't.)

My wife dropped one on the kitchen floor a few years ago....and came and brought me to the scene of the disaster. What wasn't a tiny separate dedicated piece was a larger piece broken into multiple pieces. Minimal hardware....the darn thing looked like it might have been "snapped" together...bit every "snap together" male piece was sheared off in the female part. Looked like someone had dumped a 100 piece mechanical jigsaw puzzle on the kitchen floor. All I could do was laugh!

So, back to the analogy....

928s and air cooled 911s are the "chrome toasters". Just replace the cord every once in a while and they will last forever.

Everything built after the Japanese arrived at Porsche are "plastic toasters". Lord help you if you own one after the warranty is over.

Thanks for sharing your time to explain this. Very helpful and informative !
