LF957(N or Z)RPDA
The Watts LF957NRPDA and LF957ZRPDA are reduced pressure detector assemblies (RPDA). They are available in 2 1/2″-10″ sizes and have been in production since 2013. Their bodies are made of stainless steel. The LF957NRPDA is an “N” shaped device and the LF957ZRPDA is a “Z” shaped device but they share the same parts. Both utilize a 3/4″ LF919 for the bypass assembly. The LF957NRPDA and LF957ZRPDA are private labels of the Ames LFC500N and LFC500Z.
