Straight rod coupling from TPMC is designed to join hanger rod of equal diameter, or to connect expansion anchor directly to 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.
