Street Elbow, 90 Degree, Spigot x Slip PVC Schedule 40 1-1/2" (409-015)

This 1-1/2" Schedule 40 PVC 90 Degree Street Elbow (Spigot x Slip) provides a compact, all solvent-cement right-angle direction change that connects directly off an existing socket fitting hub without requiring an intermediate pipe section or nipple between the upstream fitting and the elbow inlet. Constructed in white Schedule 40 PVC, it offers reliable performance in commercial plumbing, irrigation, and light industrial applications where a tight, low-profile 90-degree turn is required directly at a socket fitting port in an all-cemented assembly — producing a more compact corner assembly than a standard Slip x Slip elbow, which requires a pipe section on both sides.

The spigot (male plain end) inlet is sized to insert directly into the hub of any standard 1-1/2" socket-end fitting — tee branch outlet, cross port, coupling end, elbow outlet, or valve body — and is solvent-cemented in place to form a permanent, leak-free joint at the outer face of the hub. The slip socket outlet accepts a 1-1/2" PVC pipe end for a permanent solvent-cement bond on the downstream direction-change leg, redirecting the pipe run 90 degrees from the hub face. This Spigot x Slip configuration is the all-socket counterpart to the threaded street elbow concept — where the MPT x FPT street elbow (412 series) threads directly into a female-threaded port without a nipple, the 409 series cements directly into a socket fitting hub without an intermediate pipe section; the result is the same space-saving compact corner assembly applied to all-cemented socket PVC systems. This elbow is the correct choice wherever a direction change must occur immediately at a socket fitting hub with minimum projection beyond the fitting face — at tee branch outlets requiring an immediate turn, in panel-mounted assemblies where projecting nipples would exceed clearances, and in any close-quarters layout where eliminating the pipe section between a fitting hub and a standard elbow meaningfully reduces the assembly footprint.

Rated to approximately 330 psi at 73°F, this elbow is suited for standard commercial and light industrial pressure service. Its PVC composition provides excellent resistance to corrosion, scale, chlorinated water, and a broad range of chemical exposures, making it a reliable long-term alternative to metal fittings in moisture-prone or chemically active environments. NSF/ANSI 61 listing confirms suitability for potable water contact.

Apply solvent cement to the spigot exterior and the interior of the receiving socket hub per ASTM D2564 procedures, inserting fully and holding briefly for initial set. Apply solvent cement separately to the 1-1/2" pipe end exterior and the fitting's slip socket interior before inserting the pipe fully and maintaining a quarter-turn during assembly for even cement distribution. Plan the outlet direction of the elbow before cementing the spigot into the upstream fitting hub — the downstream slip socket outlet direction is fixed once the spigot joint is cemented and cannot be adjusted after cure. Allow adequate cure time before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Produces a compact 90-degree direction change directly off tee branch outlets, cross ports, and manifold socket hubs in agricultural and municipal irrigation systems where space constraints at fitting hub locations preclude the use of a standard Slip x Slip elbow with an intermediate pipe section between the upstream fitting and the direction change
• Commercial Plumbing — Provides a tight, low-profile right-angle turn at socket fitting hubs, valve body socket outlets, and panel penetration fitting ports in commercial building water distribution systems where the compact spigot-direct-to-socket assembly reduces projection beyond the fitting face at constrained installation points
• Fire Suppression Systems — Creates compact direction changes directly off tee branch outlets and cross ports in Schedule 40 PVC fire suppression distribution systems where branch drops and header turns must occur with minimum projection beyond fitting hub faces in tight ceiling and wall plenum installations
• Industrial Process Piping — Provides a compact all-socket direction change at tee branch outlets, manifold ports, and equipment socket connections in water treatment, chemical processing, and manufacturing facilities where close-quarters fitting assemblies require direction changes directly at socket hub faces without intermediate pipe sections
• Water Treatment & Aquaculture — Used at filter housing socket outlets, pump connection tee branches, and recirculating system manifold ports where a 90-degree turn must occur immediately at the socket fitting hub face with minimum projection in compact equipment enclosures and tight mechanical spaces where NSF/ANSI 61 compliance is required throughout the all-socket assembly
• HVAC & Mechanical Systems — Produces compact 90-degree direction changes directly off socket fitting hubs on cooling tower supply headers, chilled water distribution tee branches, and chemically treated water system manifold ports within the Schedule 40 pressure class where tight spatial clearances at fitting hub locations favor the spigot street elbow over a standard slip elbow plus intermediate pipe section
