Conduit Bushing 1-1/2 in Threaded
The L.H. DOTTIE PB150 is a plain thermoplastic conduit bushing with a 1-1/2 inch threaded connection. It provides a smooth entry point for cables passing through conduit ends or enclosures. Electricians and maintenance technicians use it to protect wire insulation from sharp edges during pulls. The fitting suits residential, commercial and light industrial raceway systems.
Thermoplastic Construction Benefits
The moulded thermoplastic body resists corrosion, moisture and many common chemicals found on job sites. Its non-metallic material eliminates the need for separate grounding of the bushing itself. The plain surface allows cables to slide freely without snagging on threads or burrs. Threaded design secures firmly to compatible conduit or hub openings.
Verify Thread Compatibility Before Ordering
Confirm that the conduit or enclosure has matching 1-1/2 inch threads before purchase. Check that the cable bundle diameter fits through the bushing bore without exceeding fill limits. Ensure the ambient temperature range suits thermoplastic ratings for the installation environment. Orders of 75 or more qualify for manufacturer direct shipping.

Questions about this item
Will the 1-1/2 in threaded thermoplastic bushing need replacement after prolonged exposure to UV or chemicals?
The PB150 is moulded from thermoplastic rated for standard conduit use; inspect periodically for cracking or discolouration and replace if the threads no longer seal tightly.
What is the first limit reached when the bushing protects cables pulled continuously through a 1-1/2 in raceway?
Friction and heat from sustained cable pulling will degrade the plain thermoplastic surface before the threads strip, so lubricate pulls and monitor for groove wear.
Does the DOTTIE PB150 generate noticeable heat or noise when conduit runs carry heavy loads all day?
As a passive threaded fitting it produces no noise and negligible heat; the thermoplastic body simply insulates the cables without adding thermal load.
