Metal ferrule---an important part of conduit connectors
As we know, zinc plated steel ferrule is an important part of liquid tight metal conduit fittings.
It is used to insulate the sharp cut edge of metallic flexible conduit so that cables passing through the flexible conduit will not be damaged.
Generally speaking, there are two types: split/flared type and screw/threaded type. Size range is from 3/8" to 4", and other sizes are also customized.
Besides the steel ferrule, we can also produce brass or stainless steel ferrule to meet your special requirements.
