The 845 is a reduced pressure assembly. This assembly was produced from 1978-1998. It uses the same design as the 825Y except that the body is made of a glass fiber reinforced nylon instead of bronze. The rubber parts are slightly different from the 825Y.
Common repair parts are a very small subset of the 10,000 plus items BAVCO stocks.
