Overview
The Bridgeport 325 plastic bushing is a 1-1/2″ trade-size conduit fitting engineered for terminating threaded rigid and IMC (intermediate metal conduit) at electrical boxes and enclosures. Each bushing is temperature rated to 105°C and constructed from durable plastic material that resists corrosion and chemical degradation. Sold in convenient boxes of 100 units, this product is ideal for bulk electrical construction, panel building, and industrial maintenance applications where code-compliant conductor protection is essential.
