bendix power disc brake check valve

What does the correct power disc brake check valve look like. The one on my RR has three fittings on it with only one being used going to the intake. The plastic has dried out and cracked which is causing a leak now. I'd like to get the correct one to put in there and rather not have to put some generic one that looks like garbage in its place.

Thanks for the help.

Three fittings? That's interesting, the most I've ever seen have been two. I'm no expert but I believe '69 was the first year for the push in 90 degree style check valve versus the screw in style. I've seen a number of cars with the two fitting version where the second small fitting was either capped or fed the cruise control servo. I'm guessing this would be the correct one for you.

Booster Check Valve

yes, thats what I meant by a three fitting. One of the fittings goes into the booster.
