When Your Projects Can’t Settle for 2nd Best, AMFICO Insulated Bushings Keep You Safe & Secure
Simple Snap-On Design Will Not Pull Off During Wire Pulls


AMFICO’s non-metallic insulated bushing with trade sizes of 1/2″ to 4″  provides a tight secure fit on EMT. It has plastic construction to resist corrosion for longer service life. The bushing has reinforced ribs for added grip and impact-resistant plastic insulation to protect wires from damage. Provide an EZ Pull ever for large diameter wire. Material, as molded, is able to withstand temperature up to 105 ° C.  This insulated bushing is suitable for use with all EMT conduit. 2-1/2″ thru 4″ suitable for use with Rigid/IMC Conduit.

Our EIB EMT insulated bushings are manufactured from polypropylene a  thermoplastic polymer. Its characteristics are chemical resistance, high strength, and durability maintains elasticity fatigue-resistant and is non-deforming under load or heat. It has been rated for chemical safety and is one of the safest polymers for humans.

Since plastic insulated bushings are safety components in your electrical project, avoid the “off-shore” knockoffs where material and reliability are not a given.
