Cantex 5133591 5 Series PVC Expansion Coupling

The Cantex 5 Series PVC Expansion Coupling family, which includes model 5133591, is engineered to join sections of PVC conduit while accommodating linear movement caused by thermal expansion and contraction. This listing covers multiple model numbers within the Cantex 5 Series expansion coupling line, each sized to match a corresponding standard PVC conduit trade size, so installers can select the model that matches the conduit run they are working with. Manufactured from rigid PVC across the entire family, these expansion couplings allow electrical contractors and installers to maintain a continuous, protected raceway across structures, slabs, and long straight runs where temperature-driven length changes must be absorbed without stressing the conduit system or the coupling joint itself. As part of the Cantex 5 Series family, these expansion couplings are built to complement other Cantex PVC conduit, fittings, elbows, and couplings, giving installers a consistent, compatible system of components sourced from a single manufacturer. Expansion couplings like these are a standard requirement on many PVC conduit installations where local code or engineering practice calls for expansion fittings at defined intervals, particularly in exposed or above-grade runs subject to temperature swings. The lightweight PVC construction shared across every model in the family makes these couplings easy to handle and install using standard solvent-weld techniques common to PVC conduit systems, while the PVC composition also offers corrosion resistance compared to metallic conduit fittings, making them a practical choice for a wide range of installation environments.

Key Features

  • Model Selection: Available across 12 model numbers in the Cantex 5 Series expansion coupling line, each corresponding to a specific PVC conduit trade size.

Cantex 5133736 – Frequently Asked Questions

1) What does a PVC expansion coupling actually do on a conduit run, and do I need one?
A Cantex 5 Series expansion coupling joins two sections of PVC conduit while letting the run change length as temperature rises and falls. The sliding joint absorbs that linear movement so the conduit and the glued joints aren't stressed. You need one where local code or the engineer's detail calls for expansion fittings at set intervals, which is most common on exposed or above-grade runs that see real temperature swings. A fully buried run at stable ground temperature usually doesn't move enough to require one.
2) How does the Cantex 5 Series expansion coupling connect to the conduit, glue or threads?
Solvent-weld. Both ends are plain PVC sockets you prime and cement the same way you'd glue any PVC conduit coupling, so no threading, no tape, no special tooling. If your run is threaded rigid metal conduit, this is the wrong fitting, you'd need a PVC terminal adapter or threaded transition to get onto the PVC side first.
3) How do I pick the right model number in the Cantex 5133591 expansion coupling family?
Each model in the family corresponds to one standard PVC conduit trade size, so you match the model to the conduit you're running rather than ordering a universal part. There are 12 models across the line: 5133591, 5133695, 5133696, 5133733, 5133734, 5133736, 5133742, 5140046, 5144032, 5144034, 5144035 and 5240102. Order by the model that matches your trade size.
4) Will a Cantex 5 Series expansion coupling fit conduit from another manufacturer?
The 5 Series couplings are built to pair with Cantex PVC conduit, elbows and fittings for consistent sizing across the raceway. They're solvent-weld sockets sized to standard PVC conduit trade sizes, so staying within one manufacturer's system is the surest way to keep the socket fit and sizing consistent across the job.
5) Can I use this expansion coupling as a plain conduit coupling to join two pieces of PVC?
You can glue it in like a coupling, but it isn't a substitute for one. An expansion coupling has a sliding joint whose whole purpose is to take up movement, so using it where no expansion is needed is wasted cost and extra length in the run. For a straight joint with no movement to absorb, use a standard Cantex 5 Series solvent-weld coupling instead and save the expansion fittings for the intervals the code or drawing specifies.
6) Is a PVC expansion coupling a good choice for a corrosive or wet environment versus a metal fitting?
Rigid PVC is the reason a lot of specifiers go this route. It resists corrosion where a metallic conduit fitting would attack, and it's lighter to handle on a long overhead run. The trade-off is the one that drives the whole product: PVC moves more with temperature than metal, which is exactly why an expansion fitting belongs in the run.
7) Where in a run should the expansion coupling go on an exposed above-grade PVC installation?
Typical practice is at the intervals the engineer's detail or local code sets for the run length and expected temperature swing, and at points where the conduit crosses from one structure to another or passes a building expansion joint. The 5 Series couplings are intended for commercial and industrial runs, long straight runs needing expansion accommodation, and above-grade or exposed installations, which is where the movement shows up.
