Kraloy MR4030 4" x 3" PVC Reducing Bushing
The Kraloy MR4030 is a rigid PVC reducing bushing designed to transition electrical conduit runs from a 4" trade size down to a 3" trade size within rigid PVC conduit systems. Molded from rigid PVC, this reducing bushing gives electrical contractors a dependable, corrosion-resistant way to step down conduit diameter at enclosures, boxes, and other transition points without introducing dissimilar materials into an all-PVC raceway. The 4" x 3" reducing configuration is sized to mate cleanly with standard rigid PVC conduit, helping maintain a smooth, continuous pathway for conductors as the conduit run changes size. Kraloy engineers this bushing as part of its broader line of rigid PVC conduit fittings used across commercial, industrial, and residential electrical installations.
