Water pressure reducing valve

[olefin32]

I have a Watts 25AUB 3/4 inch valve and need the repair kit.

Haven't been able to find one at local plumbing supply stores. They all want to sell me a new valve but all I need is the rubber disk.
Part number 0864943

Thanks

My boyfriend may be able to help you out with this. I will talk to him and get back to you.
