Hey Jon, happy to help.
Yes, I was able to find the replacement parts to # BM44YR. The 90 degree angle # BM99RR and the check valve # BM98GR have 1/2" MPT fitting that connect directly to your B&B RV Water Center. So no worries about compatibility or leaks due to wrong fitment.
What caused the need for those those replacement parts?

Just went through a hard time trying to fix dripping leaks in my Nautilus water system on my 5th wheel. The 90degree elbow can develop leaks in the threads! Pin hole leaks can occur and are nearly impossible to locate. This would cause water to escape out of the thread connection and not the swivel connector side. Also the cone washers you can buy at the local hardware store are a little taller and extend past the end of the nipple. This may cause the cone not to seat properly when being tightened. I discovered this after comparing the old to the new cones I purchased. I took a razor blade and cut off the top of the cone that extended past the nipple...........leak stopped immediately.
