Kraloy 078573 4" Schedule 40 PVC Standard Radius 30° Elbow, Plain End (SPxSP)
The Kraloy 078573 4" Schedule 40 PVC Standard Radius 30° Elbow is designed for electrical conduit systems that require a controlled, gradual change in direction without the sharper turn of a long-radius or 90° fitting. Manufactured from Schedule 40 PVC, this standard radius elbow features plain end (SPxSP) spigot connections on both ends, allowing for solvent-weld (cemented) joints that create a permanent, corrosion-resistant seal. As a non-metallic conduit fitting, it is well suited to underground, wet, and corrosive environments where metallic fittings may be prone to rust or degradation. The 4" trade size and 30-degree bend angle make this elbow a practical solution for routing rigid PVC conduit runs around obstructions while maintaining a smooth interior bore for wire and cable pulling.
Key Features
- Trade Size: 4" sizing designed to mate directly with 4" Schedule 40 PVC conduit and fittings.
- 30-Degree Standard Radius Bend: Delivers a gradual 30° directional change that reduces strain on conductors during wire pulling compared to sharper-angle fittings.
- Plain End (SPxSP) Spigot Connections: Both ends are plain/spigot style, ready for solvent-weld cementing to Schedule 40 PVC conduit without the need for threading or additional hardware.
- Schedule 40 PVC Construction: Rigid PVC material provides corrosion and chemical resistance for long-term performance in above-ground, underground, and direct-burial applications.
- Non-Metallic, Non-Conductive Material: PVC construction eliminates the risk of corrosion associated with metallic conduit fittings in damp or corrosive environments.
- Model 40STD4030: Standard radius elbow configuration engineered to Schedule 40 dimensional specifications for a consistent, reliable fit.

Why Kraloy?
Kraloy manufactures Schedule 40 PVC conduit fittings, including this 4" standard radius 30° elbow, to consistent Schedule 40 dimensional standards for a dependable, code-compatible fit with rigid PVC conduit systems. The plain end (SPxSP) spigot design simplifies installation through solvent-weld cementing, while the rigid PVC construction resists corrosion, moisture, and chemical exposure far better than comparable metallic fittings. For electrical contractors seeking a reliable, non-conductive elbow fitting for demanding conduit routing applications, the Kraloy 078573 offers consistent quality and Schedule 40 compatibility.

Kraloy 078625 – Frequently Asked Questions
1) What trade sizes does the Kraloy Schedule 40 PVC standard radius elbow come in?
Three trade sizes: 2 inch, 3-1/2 inch, and 4 inch. The MPNs are 078625 for the 2 inch, 078548 for the 3-1/2 inch, and 078573 for the 4 inch. Each is sized to mate directly with Schedule 40 PVC conduit of the same trade size, so pick the size that matches the run you are already pulling.
2) Do I need glue for these Kraloy PVC elbows, or do they thread on?
They glue. Both ends are plain end (SPxSP) spigot, meant for solvent-weld cementing to Schedule 40 PVC conduit. There is no threading and no clamps or set screws involved, so you will need PVC conduit cement and primer on the truck. The cemented joint is permanent once it sets, so dry-fit the run first.
3) What is the difference between the Kraloy 078548 Schedule 40 PVC elbow and the Carlon UA7AL-CAR elbow?
Both are Schedule 40 PVC plain-end elbows that solvent-weld to rigid PVC conduit, but they differ in bend angle and trade size. The Kraloy standard radius elbow is a plain end SPxSP fitting offered in 2 inch, 3-1/2 inch and 4 inch trade sizes. The Thomas & Betts UA7AL-CAR is a 3 inch Schedule 40 PVC 45 degree plain-end elbow in gray, from the Carlon series. Choose by the turn the run needs and the conduit size it has to mate with.
4) I need a 3-inch PVC conduit elbow - will the Kraloy 078548 work?
No. The Kraloy 078548 is a 3-1/2 inch Schedule 40 PVC elbow, and the related sizes are 2 inch and 4 inch, so none of them will solvent-weld to 3 inch conduit. For a 3 inch run, the Thomas & Betts UA7AL-CAR is a 3 inch Schedule 40 PVC plain-end elbow, though it turns 45 degrees rather than 90.
5) Can this Kraloy PVC elbow be direct buried or used in a wet location?
Yes. The elbow is rigid Schedule 40 PVC, non-metallic and non-conductive, and the description calls out above-ground, underground, and direct-burial use along with wet, damp, and corrosive environments. That is the main reason crews choose it over a metal elbow, which can rust in those conditions.
6) Will a Schedule 40 PVC elbow fit Schedule 80 conduit of the same trade size?
Yes, on the outside diameter. Schedule 40 and Schedule 80 PVC conduit share the same OD at a given trade size, so a Schedule 40 socket or spigot fitting joins either. Schedule 80 has a thicker wall and a smaller bore, so where the spec calls for Schedule 80 because the conduit is exposed to physical damage, use a Schedule 80 fitting to stay consistent with the drawing.
7) Will a standard radius PVC elbow work for pulling large cable, or do I need a long sweep?
A standard radius elbow is the tighter of the two options and is used for routing around obstructions in a rigid PVC run. For long pulls or large stiff conductors, a long radius (sweep) elbow of the same trade size gives you a gentler bend and less sidewall pressure on the cable. If the pull calculation is marginal, go to the sweep rather than the standard radius.
8) Can a 45 degree PVC elbow be used in place of a 90 degree elbow on a conduit run?
Only if the geometry of the run allows it. The Kraloy 078548 is a 90 degree standard radius Schedule 40 PVC elbow, which makes the full quarter turn in one fitting. The Thomas & Betts UA7AL-CAR is a 45 degree Schedule 40 PVC plain-end elbow, so a quarter turn takes two of them plus a short nipple between, which adds joints and changes the bend allowance accounting for the pull. Both use plain-end solvent-weld connections to rigid PVC conduit.
9) Is a PVC elbow OK where conduit comes out of the ground into a panel?
Rigid Schedule 40 PVC handles the buried portion fine, and these plain-end elbows are made for underground and direct-burial runs. Where the conduit emerges and is exposed to physical damage, many specs call for a Schedule 80 PVC or metal sweep for that section instead. Check what the drawing calls for at the stub-up before committing the run.
