NPT and MG nylon cable glands provide threaded cable entry with a sealing insert, washer and locknut. Select the thread family and cable diameter together, then check the body height, thread length and spanner dimensions against the installation. The NPT and MG dimensional schedules are separate and their thread designations are not interchangeable.
