Why Choose the DUO40MR-BR Conduit Fitting?
The DUO40MR-BR is a Sealcon DUO Ms conduit fitting that combines strain relief and conduit connection in one nickel plated brass body. It uses a M40 x 1.5 thread, accepts .79" - 1.02" (20 - 26 mm) cable O.D., and fits nominal conduit size 29.
The partially rotatable design helps align conduit routing during installation, while the included O-ring supports sealed entry points. It is a practical option for machine wiring, panel cable entry, automation equipment, and conduit runs that need both grip and protection.
