Product Details

Reducing rod coupling from TPMC is designed to adapt and join hanger rod of different diameter, or to transition expansion anchor to larger hanger rod. It delivers precise alignment and reliable load transfer while effectively resisting upward thrust, vibration, and thermal movement.
By simplifying installation and ensuring long-term pipe stability, it is a trusted component for fire sprinkler and mechanical piping systems.
