Thomas & Betts E950NL 4" x 3" Non-Metallic Schedule 40/80 PVC Reducer Bushing

The Thomas & Betts E950NL is a 4" x 3" Schedule 40/80 PVC reducer bushing designed to transition between two conduit trade sizes within a non-metallic conduit system. Manufactured from durable, non-metallic PVC as part of the Carlon family of conduit fittings offered under the Thomas & Betts brand, this reducer bushing provides a corrosion-resistant connection point for stepping down from a 4" conduit run to 3" conduit. Reducer bushings like the E950NL are a common solution when a larger conduit run needs to connect to smaller conduit, equipment, or enclosures without switching to a full reducing coupling. The PVC construction suits Schedule 40 and Schedule 80 PVC conduit systems that call for lightweight, corrosion-resistant components throughout the raceway.

Key Features

  • Trade Size: 4" x 3" reducer bushing sized to transition a 4" conduit opening down to 3" conduit.
  • Durable Construction: Non-metallic PVC material resists corrosion, making it well suited to conduit environments where metallic fittings may degrade over time.
  • Schedule 40/80 Compatibility: Designed for use with Schedule 40 and Schedule 80 PVC conduit systems, supporting consistent fitment across common PVC raceway installations.
  • Non-Metallic Design: Eliminates the corrosion concerns associated with metallic reducer fittings, helping maintain a consistent non-metallic conduit system from run to run.
  • Reducing Function: Allows a transition from larger 4" conduit to smaller 3" conduit without changing the type of conduit material used in the run.
  • Carlon Fitting Family: Manufactured as part of the Carlon line of non-metallic conduit fittings offered under the Thomas & Betts brand, a recognized name in conduit and raceway components.
  • Lightweight Fitting: PVC construction keeps the reducer bushing lightweight relative to metallic alternatives, simplifying handling and installation.

Thomas & Betts TBE950NL – Frequently Asked Questions

1) What size conduit transition does the Thomas & Betts E950NL reducer bushing make?
The E950NL steps a 4 inch conduit opening down to 3 inch conduit. It is a 4" x 3" reducer bushing, so the larger side seats in the 4 inch hub or opening and the 3 inch conduit lands in the reduced side. If you need to go from 4 inch straight to a smaller size than 3 inch, this is not the bushing for that step.
2) Will the E950NL work with both Schedule 40 and Schedule 80 PVC conduit?
Yes. The Carlon E950NL is built for Schedule 40 and Schedule 80 PVC conduit systems, so it fits either wall type on a 4 inch to 3 inch step. That matters on jobs where the run changes schedule, such as Schedule 80 above grade for physical protection and Schedule 40 below, since one fitting covers both.
3) Should I use a reducer bushing or a reducing coupling to go from 4 inch to 3 inch PVC?
A reducer bushing like the E950NL drops into an existing 4 inch opening, hub, or fitting and gives you a 3 inch landing, which is the quick fix when the larger size is already prepped at a panel, enclosure, or junction point. A reducing coupling is the choice when you are joining two lengths of conduit mid-run and need a fitting with sockets on both ends. If the 4 inch hole or hub is already there, the bushing is the simpler part.
4) Is a non-metallic bushing a good idea for an underground or corrosive conduit run?
PVC is the usual answer in those conditions. The E950NL is non-metallic PVC, so it does not corrode the way a steel or aluminum reducer will in wet, buried, or chemically aggressive locations, and it keeps the raceway all-PVC instead of mixing a metal fitting into a plastic run. It is also lighter to handle than a metal reducer at the 4 inch size.
5) What part number do I order for the 4 inch to 3 inch Carlon PVC reducer bushing?
Order Thomas & Betts E950NL. That is the manufacturer part number for the 4" x 3" non-metallic PVC reducer bushing in the Carlon fitting line, and the model is sold as a single configuration, so there are no finish or schedule variants to specify.
6) What color is the Carlon E950NL PVC reducer bushing?
Gray, which is the standard color for Carlon Schedule 40 and 80 electrical PVC, so it blends with the rest of a gray PVC raceway rather than standing out at the transition point.
