What's the shelf life of brake fluid? Asking about fluid in a previously opened container but the fluid isn't used, and brand new in a sealed unopened container. If I check the moisture is that a good enough indicator that it's good or not?

Not sure how useful my experience/perspective is, but...

All my brake fluid is SRF (thank-you, FCP Euro), which is is supposedly less hygroscopic than many fluids, and even its wet boiling point is still high enough for street use. So, for the Mazda, I'll use unsealed but unused brake fluid as long as my brake fluid test pen shows no moisture. I know pens are not super trustworthy, but SRF is such hilarious overkill that I figure I'm okay using it as long as the pen reads zero moisture on all its modes.

...But for the M3, I'll still only use fluid from sealed, unopened containers (largely because occasional track time).

Unopened and sealed is good forever. If opened for more than a year (and I write the date I opened it on the bottle) it gets pitched.

I used a PVC pipe fitting, although it was a special fitting I got from a store I used to work at that sold hot tubs. It was a repair fitting so you won't find it locally but here are some pictures and a part #.

I see I sanded it around the permiter slightly for a better fit. My memory is terrible but I'm almost positive I used this.

Edit: You may be able to get this locally, it slips over a 2" fitting, we sold them as well as another shop in our small Nebraska town.
