Ipex Scepter 078104 PVC Bushing
The Ipex Scepter 078104 PVC Bushing is an economical PVC solution that excels in corrosion resistance and low upfront cost for non-metallic conduit systems. It’s the most budget-friendly option here and performs well in wet or chemically aggressive environments compared with metal alternatives like the IBERVILLE EB75-10 and Bridgeport grounding bushing, though it does not provide grounding continuity. For buyers specifying conduit bushings on a tight budget or in plastic-pipe systems, its low material cost and chemical resilience make it a practical selection.
Rustproof PVC — no flakes
Flexible lip — bend friendly
