Raybestos CV89022 Professional Grade Brake Power Booster Check Valve

The media could not be loaded.  Fits my 1985 corvette perfectly, used lithium grease and a little bit of persuasion to pop it in. Seals perfectly to preexisting brake booster!

I don't think the missing grommet is Raybestos fault, think people are abusing the amazon return policy. Taking the grommet and returning the vavle to get their money back, thats what I think.Update: second one arrive, again no grommet. When you call the Raybestos customer support number privided by Amazon, it says the number can't go through.Update: ordered a 3rd one, this time it came with the grommet

Brake booster check valve installed and worked perfectly.

This is a rare part as far as vacuum valves go. Came in great shape and worked well on my odd and rare 65 impala brake booster.

First one arrived and grommet was missing. Returned it and luckily the replacement did include the grommet. Works great. Taking off 1 star due to the hassle.

It's not exactly the same as one I was replacing on a 35 year old car, but it fit. Works just fine.

My original valve sealed tightly when you tried to blow through it. I've bought two of these now and they don't actually close properly to hold the vacuum in. They do fit the booster for the Corvette properly, so I'm basically using it as a fitting and attaching a working check valve on the hose in front of it

Photo show grommet with check valve. I bought one when I opened the box there was no grommet. I tried to contact Raybestos but number was no good. I sent it back and ordered another one. The second one came with out the grommet also. Photo is misleading.

Only the valve showed up, in a raybestos box, but no rubber grommet.Lucky I only needed the valve, but don't buy this if you need the rubber part.
