Cantex 51400 Series PVC Conduit End Cap, 3" Trade Size

The Cantex 51400 Series PVC Conduit End Cap is a purpose-built end closure designed to seal the open end of 3" PVC conduit runs. Molded from durable PVC, this conduit cap provides a clean, weather-resistant termination point for electrical raceway systems, helping keep out moisture, dirt, and debris during storage, staging, or permanent installation. This listing covers the full 51400 Series model lineup — 11 model options (5140031 through 5140042) — all sized to fit standard 3" PVC conduit dimensions for a proper, secure fit without the need for additional adapters. Regardless of which model number is selected, every option in the series shares the same PVC construction, 3" trade size fit, and end-cap function, so buyers can standardize on the 51400 Series across a project while selecting the specific model that matches their supplier or packaging preference.

Cantex 5140033 – Frequently Asked Questions

1) Which Cantex 51400 end cap part number do I order for 2 inch PVC conduit?
For 2 inch trade size, the Cantex 51400 Series end cap is model 5140037. The series runs by trade size: 5140031 (1/2"), 5140032 (3/4"), 5140033 (1"), 5140034 (1-1/4"), 5140035 (1-1/2"), 5140037 (2"), 5140038 (2-1/2"), 5140039 (3"), 5140040 (4"), 5140041 (5"), 5140042 (6"). Order by the conduit trade size you are capping, not by outside diameter.
2) What is the largest conduit size these Cantex PVC end caps cover?
The 51400 Series tops out at 6 inch trade size, model 5140042, with 5 inch (5140041) and 4 inch (5140040) below it. The full span is 1/2 inch through 6 inch across eleven models, so one series covers everything from branch runs to large underground feeders.
3) Do I need an adapter to put a Cantex 51400 cap on my PVC conduit?
No adapter. The 51400 Series caps are molded to standard PVC conduit dimensions for the stated trade size, so the cap goes straight onto the conduit end. Match the cap's trade size to the conduit's trade size and the fit is direct.
4) Are Cantex 51400 end caps suitable for outdoor and underground conduit runs?
Yes. These are molded PVC, which resists corrosion and moisture intrusion, and the series is used on underground and above-grade PVC conduit as well as indoor work. Typical use is sealing an open raceway end against water, dirt, and debris during storage, staging, or a finished run.
5) Is a conduit end cap the right part, or do I need a bushing or a plug?
An end cap closes off the outside of an open conduit end, which is what you want for stubbed-up or staged conduit you are protecting from water and debris until it gets tied in. A bushing is a different job, it lines the inside of a termination to protect conductor insulation where wire exits. The Cantex 51400 is the closure type, not a wire-protection fitting.
6) Will a Cantex 51400 cap work on metal conduit like EMT or rigid steel?
These caps are molded for PVC conduit trade sizes, and PVC conduit outside diameters do not match EMT. For steel raceway you want a cap or plug made for that conduit type. Use the 51400 Series on PVC runs only.
7) Can I standardize on one series of PVC caps across a whole project with mixed conduit sizes?
Yes, that is the practical reason to buy the 51400 Series. Every model shares the same PVC construction and end-cap function, with only the trade size changing, so a contractor or MRO buyer can spec one series from 1/2 inch up to 6 inch and keep fit and finish consistent across the job.
