Kraloy 78624 Schedule 80 PVC 90° Standard Elbow, Spigot x Spigot
The Kraloy 78624, also referenced as model 80STD1590, is a Schedule 80 PVC 90° standard radius elbow engineered for rigid, solvent-weld conduit systems. Sized at 1-1/2" trade size, this one-piece molded PVC fitting features spigot x spigot (SPxSP) ends that solvent-weld directly into couplings, terminations, or other Schedule 80 PVC conduit fittings. The 90° standard sweep delivers a smooth, code-compliant direction change for conduit runs while preserving a generous bend radius that eases conductor and cable pulling. Built from heavy-wall Schedule 80 PVC, the 78624 elbow is designed for installations that call for the added wall thickness and mechanical protection Schedule 80 provides over lighter-duty Schedule 40 fittings.
Key Features
- Trade Size: 1-1/2" sizing for compatibility with standard 1-1/2" Schedule 80 PVC conduit runs.
- Durable Schedule 80 PVC Construction: heavier wall thickness than Schedule 40 PVC for applications requiring added mechanical protection.
- 90° Standard Radius: provides a smooth, standard-radius direction change that eases conductor and cable pulling through the conduit run.
- Spigot x Spigot (SPxSP) Ends: both ends are plain spigot ends designed for solvent-weld (glued) connection into couplings, terminations, or other PVC conduit fittings.
- One-Piece Molded Design: molded PVC construction with a smooth interior bore to help reduce friction during wire and cable pulls.
- Corrosion-Resistant Material: PVC construction resists corrosion, chemicals, and moisture common in raceway environments.
- Model Reference: identified by Kraloy model 78624 / 80STD1590 for accurate cross-reference and ordering.

Kraloy 78624 – Frequently Asked Questions
1) What trade sizes does the Kraloy Schedule 80 PVC 90-degree standard elbow come in?
Two trade sizes: 1-1/2 inch, ordered as Kraloy 78624, and 2-1/2 inch, ordered as Kraloy 78626. Pick the elbow to match the trade size of the conduit run it is going into, since the spigot ends are sized for that same trade size of Schedule 80 PVC conduit.
2) How do the spigot x spigot ends on this Kraloy PVC elbow connect, and do I need couplings?
Both ends are plain spigot ends, so they solvent-weld (glue) into a female socket. That means you need a coupling, a bell-end conduit, or a fitting hub on each side to take the spigot. It does not have its own belled sockets, so you cannot push plain-end conduit straight into it. Budget PVC cement and a coupling per end when you order.
3) Is a 2-1/2 inch Kraloy 78626 elbow the same as a 2-1/2 inch Schedule 80 female-end (belled) elbow?
No. The 78626 is spigot x spigot, meaning both ends are male plain ends that slip into a socket. A belled or female-end elbow accepts conduit directly into its own sockets. If your plan was to glue conduit straight into the elbow, you need the belled version or you need to add a coupling at each end of the 78626.
4) What should I use instead of the Kraloy 78624 elbow if the conduit run needs a 45 degree turn rather than a 90?
The Kraloy 78624 and 78626 are 90 degree standard radius elbows, so they only produce a square direction change. For a shallower offset, the Thomas & Betts UA7AL-CAR is a 3-inch Schedule 40 PVC 45 degree plain-end elbow in gray from the Carlon series. Note the two differ in more than angle: the Kraloy elbows are Schedule 80 heavy-wall PVC in 1-1/2 inch and 2-1/2 inch trade sizes, while the UA7AL-CAR is Schedule 40 in 3-inch trade size, so it suits a larger raceway built from Schedule 40 conduit.
5) Is a Carlon Schedule 40 PVC elbow an acceptable substitute for a Kraloy Schedule 80 elbow?
Not where the drawing calls out Schedule 80. The Kraloy 78624 and 78626 are molded from heavy-wall Schedule 80 PVC, which carries more wall thickness and mechanical protection than Schedule 40 fittings. The Thomas & Betts UA7AL-CAR is a Schedule 40 PVC elbow, so it belongs on Schedule 40 runs rather than in a Schedule 80 raceway specified for added physical protection. The bend angle differs as well: the Kraloy elbows are 90 degree, and the UA7AL-CAR is a 45 degree.
6) Can I use a Schedule 80 PVC elbow on a Schedule 40 conduit run?
Yes. Schedule 40 and Schedule 80 PVC conduit share the same outside diameter and socket dimensions at a given trade size, so a Schedule 80 elbow solvent-welds into Schedule 40 couplings and bell ends. The difference is wall thickness: Schedule 80 is the heavier wall, which is what you want where the raceway is exposed to physical damage. Inside bore is slightly smaller, so check your conduit fill if you are at the limit.
7) Is a standard radius 90 elbow enough for pulling large conductors, or do I need a long sweep?
The Kraloy 78624 and 78626 are standard radius 90-degree elbows, which handle normal direction changes and ease conductor pulling compared with a tight fitting bend. For heavy feeders, long pulls, or service laterals where pulling tension is the concern, a long sweep or special radius 90 is the better choice. Standard radius is the usual pick for branch and feeder runs on commercial and industrial work.
8) Can this PVC elbow be used underground and in direct burial duct runs?
Yes. Kraloy lists these Schedule 80 elbows for both underground and exposed PVC conduit installations, and the PVC resists corrosion, chemicals, and moisture. Solvent-welded joints are what make the run watertight, so cement both spigot ends properly on buried work.
9) Will a PVC elbow work where the conduit is exposed to physical damage?
That is the case for Schedule 80 specifically. The Kraloy Schedule 80 elbows use heavier wall construction than Schedule 40 for applications requiring added mechanical protection, which is why Schedule 80 is the usual spec for exposed PVC risers and areas subject to damage. Keep the whole run Schedule 80, not just the fitting.
10) Will this Kraloy elbow match the rest of my PVC conduit system for cross-reference and ordering?
The 1-1/2 inch is Kraloy 78624, also carried under the model reference 80STD1590, and the 2-1/2 inch is Kraloy 78626. Material is PVC throughout, one-piece molded with a smooth bore. Using the Kraloy model numbers on the order avoids mixing a Schedule 40 fitting into a Schedule 80 run.
11) Do plain-end and spigot x spigot elbows join the same way?
Both are solvent-weld style ends with no bell, so they glue into couplings, terminations, or other PVC fittings rather than receiving conduit directly. The Kraloy 78624 and 78626 have spigot x spigot ends on a 90 degree standard radius body, and the Thomas & Betts UA7AL-CAR is described as a plain-end elbow. The practical difference on the job is schedule and size compatibility, not the joining method: match the fitting's schedule and trade size to the conduit and coupling you are welding into.
