High Quality, Perfect fit.
High quality, perfect fit. Mine went in a WJ: 2001 Jeep Grand Cherokee 4x4 4.0. It doesn’t come with the rubber grommet because that is a separate part that lasts much longer than a check valve. If you already ripped your grommet out of your brake booster, order that, too. If your grommet looks worn, cracked, or warped, order it! The hose fitting is also spot on correct. If your hose is loose, trim the stretched end. If it’s still loose, it needs to be replaced. If you just replaced it & it doesn’t fit, the hose is the wrong size. This little valve is the center of a team that manages your air pressure in your brakes. Brakes are important. Doing this repair wrong can kill you & other people on the road. If this is a struggle for you, this part is not to blame. Hunt down the real problem or get a certified mechanic!

Butt…It got the job done…
So far it got the job done , not the best quality..but like I said it got the job done. Felt like it was recently 3d printed… buttt it got the job done. Fit well, easy to use , long term functionality is to be determined though. These things should not cost as much as they do in all honesty… just make sure you get the right part and you should be okay.

Ok, but you may need to buy a separate grommet.
It works, but the large end is slightly smaller than the OEM, so it was slightly loose in the grommet. They should have provided the appropriate grommet with it.

Doesn't work for 2005 expedition. Eddie bauer
The hose from a 2005 expedition Eddie Bauer is too big to fit on this. It's too bad because the OEM part is near impossible to find apart from wreckers
