W-PB-4 Powder Bulb

Dry Method Magnetic Particles are applied by the inspector with a Powder Bulb.  Western’s W-PB-4 has been custom designed for this application.  This is the best development in Dry MPI Powder Application in 20 years!

The W-PB-4 has an easy to remove rolled aluminum end cap with an extra large mouth to easily fill with powder.  The W-PB-4-M is equipped with an adjustable magnet for overhead work. 

The W-PB-4 is manufactured with Silicon Rubber, so its characteristics are not affected by cold or hot weather.  The Silicon Rubber will not harden with age, or crack due to age or cold weather.
