Multi Fittings 78366 Reducer Bushing 3x2.5 in Pvc

Product Description

The MULTI FITTINGS 78366 is a PVC reducer bushing designed to transition a 3-inch trade-size conduit opening down to a 2.5-inch trade-size opening within a rigid PVC conduit system. This insulating bushing is manufactured from nonconductive PVC, which eliminates the risk of a dangerous second point of contact and removes the need for metallic bonding at the fitting. Weighing 0.295 pounds, it is lightweight enough for overhead and confined-space installations. The material provides strong resistance to a broad range of acids, alkalis, and salt solutions, making it well suited for corrosive or chemically active environments. Licensed electricians typically install this fitting as part of a complete nonmetallic conduit assembly.

This reducer bushing is used in rigid PVC conduit systems where a larger conduit or enclosure knockout must be reduced to accept a smaller conduit run. Common applications include industrial, commercial, and residential electrical installations where corrosion resistance or nonmetallic construction is required — such as wastewater facilities, chemical plants, coastal construction, and underground raceway systems. The Kraloy Rigid PVC Fittings product line, of which this part is a member, includes a full range of adapters, couplings, elbows, access fittings, and expansion fittings designed to work together as a complete conduit system.

Key Features

• Transitions 3-inch trade-size to 2.5-inch trade-size in a rigid PVC conduit system
• Nonconductive PVC construction eliminates dangerous second point of contact
• Resistant to a wide range of acids, alkalis, and salt solutions
• Corrosion resistant for reduced maintenance and extended service life
• Lightweight at 0.295 pounds for easy handling in overhead or confined installations
• High impact and tensile strength despite low weight

Compatibility

Designed as an OEM-style replacement or new-installation component for rigid PVC conduit systems requiring a 3-inch to 2.5-inch trade-size reducer bushing.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements for nonmetallic conduit systems. De-energize all circuits and verify with a meter before working in the conduit system. PVC conduit solvent cement is typically used to secure rigid PVC fittings; follow the cement and primer manufacturer's instructions for cure time before pulling wire. Do not over-ream or force-fit the bushing, as this can compromise the mechanical integrity of the joint.
