1/2″ to 6″  Plastic Non-Metallic Threaded Bushings for Rigid / IMC Conduit (PIB Series)

When Your Projects Can’t Settle for 2nd Best, AMFICO Insulated Bushings Keep You Safe & Secure
NPT Threads, Thread onto Conduit to Ensure Retention During Wire Pulls


AMFICO’s non-metallic insulated bushing with trade sizes of 1/2″ to 6″  provides female NPT threaded connection for s tight secure fit. 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 rigid/IMC conduits.    

Our PIB 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.

Certified Made in the USA

Female NPT threads avoids cross-threading or NPS issues.

Cut threads lock in place on the conduit enabling wires to be pulled without incident

Rounded corners and burr less and no flash on an ultra-smooth interior protect wires from the sharp edges.

The strength, durability, and resilience of Polyproplene will not allow the bushing to crack or warp.
