PVC Conduit End Caps & Riser Caps
Conduit caps close the open end of a conduit to keep water, dirt, and debris out — end caps for a plain seal, riser caps for a seal that still lets you tie off mule tape or a pull-line.
Innovative Plastics molds both styles in high-impact PVC and offers them in sizes that fit Schedule 40 and Schedule 80, plus EB and DB conduit, for encased and direct-burial applications. Both install in seconds with no tools and resist warping in the ground.
PVC end caps give a clean, secure closure on stored or stubbed-out conduit. Riser caps — also called rope-tie or mule-tape caps — add an underside loop so a pull-line can be tied off and left in the conduit for future cable pulls, closing the opening without losing access.
Choose an end cap when you simply need to seal a conduit, or a riser cap when you need to seal it and preserve a pull-line. The two product families are below; our Schedule 40 vs. Schedule 80 guide explains how to match a cap to your conduit.

Three product families cover the underground conduit lifecycle: sealing devices protect open conduit, duct spacers align conduit during the pour, and caps close conduit ends.
| Family | Primary purpose | Material | Size range |
|---|---|---|---|
| Sealing Devices | Seal and protect open conduit, ducts, and innerduct | Low-density polyethylene (LDPE) | 1"–8" |
| Duct Spacers | Hold conduit in alignment during trenching and backfill | High-impact polymer / ABS resin | 1"–8" duct, 1.5"–3" separation |
| Caps (this page) | Close conduit ends; riser caps add a rope-tie loop for mule tape | High-impact PVC | ½"–6" |
FAQ
Frequently asked questions
- What conduit do PVC end caps fit?
- Innovative Plastics PVC end caps fit Schedule 40 and Schedule 80 conduit as well as EB and DB conduit, for both encased and direct-burial applications. Match the cap to the conduit trade size using the size table on the product page.
- What is the difference between an end cap and a riser cap?
- An end cap is a plain closure that seals an open conduit. A riser cap seals the conduit but adds an underside rope-tie loop, so mule tape or a pull-line can be tied off and left in place for a future cable pull.
- Do conduit caps require tools or glue to install?
- No. Both end caps and riser caps push on by hand in seconds — no tools and no solvent cement required — and their high-impact PVC resists warping underground.

- Riser Caps and Mule Tape: Seal a Conduit and Keep the Pull-Line How riser caps close an open conduit while tying off a mule tape or pull-line inside, so the next crew has a ready pull string months later.
