Shell Size 12 Fit and Compatibility
The RM12BPG-B(71): The shell size 12 dimension is the critical fit parameter — this bushing mates with RM series circular connectors that share the same shell size. It is designed for use with RM series products, so confirm your connector body and backshell are also size 12 before ordering. The black color aids visual identification on the assembly bench or in a field repair kit.
