Carlon E952 Schedule 40 PVC Swedge Reducer, 4" x 3-1/2" Male x Male Gray Conduit Fitting

The Carlon E952 Gray PVC Schedule 40 Swedge Reducer provides reliable conduit size transition from 4" to 3-1/2" with male x male connections on both ends. Manufactured from durable Schedule 40 PVC material in a professional gray finish, this fabricated swedge reducer delivers dependable performance for electrical conduit systems that require a precise size reduction and a secure, code-compliant connection. Fabricated in the United States, the Carlon E952 is built for professional electrical contractors and facility maintenance crews who need a dependable transition fitting for mixed-size conduit runs. Its smooth internal swedge design keeps wire-pulling resistance low while maintaining the structural integrity expected from Schedule 40 PVC conduit fittings, making it a practical solution wherever a larger conduit run must transition down to a smaller trade size without sacrificing mechanical strength or long-term weather resistance. This fitting is well suited for both new installations and retrofit work where conduit runs shift from 4" down to 3-1/2" trade size, giving installers a single, purpose-built part instead of stacking multiple couplings and adapters. The E952 ships in minimum order quantities of 15 pieces, making it a practical stocking item for contractors managing multiple conduit runs on commercial or industrial jobsites, and its consistent Schedule 40 wall thickness supports the same mechanical protection and durability that installers expect from standard PVC conduit runs.

Carlon E952NM – Frequently Asked Questions

1) What sizes does the Carlon E952 PVC swedge reducer come in?
The E952 male x male swedge reducer covers seven trade size steps: 2-1/2" x 2" (E952KJ), 3" x 2" (E952LJ), 3" x 2-1/2" (E952LK), 4" x 3" (E952NL), 4" x 3-1/2" (E952NM), 5" x 4" (E952PN), and 6" x 5" (E952RP). The first number is the large end, the second the reduced end, so pick by the run you are coming out of.
2) Is the Carlon E952 male on both ends, and what does that mean for how I glue it in?
Both ends of the E952 are male, so it spigots into the sockets of two couplings, bell ends, or fittings rather than accepting conduit directly. If you are joining plain conduit to plain conduit, you need a female socket on each side (a coupling or a belled length) for the reducer to solvent weld into. Trying to slide raw conduit onto either end will not work.
3) Can I use a PVC swedge reducer to step 4 inch conduit down to 3-1/2 inch on a wire pull?
Yes. The swedge design tapers the wall from the 4 inch end to the 3-1/2 inch end (E952NM) instead of shouldering abruptly, so conductors ride over the transition rather than catching on a lip. That is the difference between a swedge reducer and a bushing style reduction: the swedge keeps the bore continuous, which matters on long pulls where every snag adds tension.
4) Is the Carlon E952 reducer Schedule 40 or Schedule 80?
Schedule 40 gray PVC. Match it to Schedule 40 conduit on both ends. If your spec calls for Schedule 80 because the run is exposed to physical damage, this is not the fitting for that section, though Schedule 40 and Schedule 80 share the same trade size ODs so a Schedule 80 run can still terminate into Schedule 40 fittings where the spec permits it.
5) How many Carlon E952 reducers do I have to buy at once?
The E952 sells in a 15 piece minimum. It is a fabricated fitting, not a stocked-by-the-one item, so order the whole run's worth in a single go rather than expecting to add one later.
6) Can Carlon E952 PVC reducers go in a concrete encased or direct burial duct bank?
Gray Schedule 40 PVC is the standard material for underground and concrete encased electrical duct, and the E952 is solvent welded PVC throughout, so the joint is as watertight as the rest of the run once cemented. Use the same PVC cement you are using on the conduit and let it set before the pour.
7) What is the difference between a swedge reducer and a reducer bushing for PVC conduit?
A reducer bushing threads or presses into the larger fitting and leaves an internal shoulder at the size change. The E952 swedge reducer is a length of PVC formed down from the large trade size to the small one, male on both ends, so the reduction happens over a taper in the pipe itself. Use the swedge where conductors have to pass through the transition; a bushing is for terminating into a box or enclosure, not for mid-run pulls.
8) Does a gray PVC conduit reducer hold up outdoors in sunlight?
The gray PVC used on the E952 is sunlight resistant compound, which is why exposed risers and above-grade sections of PVC duct are run in it. It is the same material family as the conduit it joins, so the reducer weathers at the same rate as the rest of the system rather than becoming the weak point.
9) Where is Carlon E952 conduit fitting made?
United States. On public and federally funded jobs with domestic sourcing language in the spec, that is the answer the submittal needs.
