Solid adapter
So I had to get this in conjunction with a pressurized brake bleeder for our 1995 Toyota pickup. Fit perfectly on master cylinder, works excellent. Bled brakes without issue. Easy to use. I had to install a larger adapter for my bleeder but the value for the money is excellent nonetheless!

Worked well for my use. 2020 Rav4 XLE Premium
Purchased to perform power bleed on 2020 Rav4 XLE premium. Performed well for this price point. The seal occurs on inside wall of reservoir (O ring on adapter). Collar used to secure adapter to reservoir. I was able to push 3 bottles of Toyota DOT 3 fluid using this adapter for all four wheels. Held 10 psi of pressure out of the box, no adjustments or corrections needed. In order to push 3 bottles of brake fluid I had to remove this adapter 9 times to refill reservoir with new brake fluid. After each reinstall, 10 psi was held, no issues. The pin and chain (used to secure collar) can be a bit of pain. Be patient. Pin, in fully inserted position, binds and can be difficult to remove. If pulling on chain to remove pin, one can distort the chain ring and can elongate, chain and pin can detach. I used 90 degree pick tool, and from the underside used to push pin upward. Worked well. Overall, for price point, I am happy. I will retain this adapter for future use.

Fits and works after modifications and cleaning for me (GX460)
This product did fit my GX460 brake reservoir with a good seal, where all the adapters that came with my different brand bleeder kit did not. However, I ran into two issues. The main being the quick connector adapter was made of steel, where the rest of the body is aluminum, so the mismatched metals had corroded significantly on mine, even new out of the box. However, the seller contacted me quickly and resolved the issue. Also note this is not a standard disconnect adapter that most other air lines use for example, but the tip can be swapped out if needed.

Works great
I use this with a power bleeder. I did modify this with a nicer NPT fitting and I had to buy an additional NPT fitting and hose to connect it to my bleeder. Not a big deal. It snaps onto the factory master cylinder reservoir with ease and it held 15psi with no leaks at all. Perfect addition to my tool chest. It is pricey, but still cheaper than having a shop do it. You will be more likely to change the fluid more often simply because you CAN.

A great tool after a little work
This adapter worked amazing after some modifying. The included male plug is a poor design and will not hold in any couplers I had. I immediately replaced it with one that worked better. The finish on the cast elbow is really rough. The main body was pitted and the threaded end that holds it to the blue cap is extremely poorly cast. It worked just enough to keep the nut on. Once the air hose plug was sealed, the cap was tested and it held pressure perfectly. It held 15psi for over an hour. By the end of the flush there was no sign of fluid that leaked out.
