Street Elbow, 45 Degree, Spigot x Slip PVC Schedule 40 2" (423-020)

This 2" Schedule 40 PVC 45 Degree Street Elbow (Spigot x Slip) provides a compact, all solvent-cement 45-degree directional offset that connects directly off an existing 2" 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 gradual 45-degree offset is required immediately at a socket fitting port in an all-cemented assembly — producing a lower-profile, more compact angled transition than a standard Slip x Slip 45 degree elbow while eliminating the additional joint that a separate nipple would introduce at the fitting hub.

The spigot (male plain end) inlet is sized to insert directly into the hub of any standard 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 2" PVC pipe end for a permanent solvent-cement bond on the downstream direction-change leg, redirecting the pipe run 45 degrees from the hub face. This Spigot x Slip configuration applies the street elbow concept to a 45-degree offset — where the 409 series (90 Degree Spigot x Slip Street Elbow) produces a compact right-angle turn directly at a socket hub, the 423 series produces a compact gentle offset at the same hub location; both eliminate the intermediate pipe section at the inlet end and both are appropriate wherever directional transitions must occur immediately at socket fitting ports with minimum projection beyond the fitting face. The 45-degree offset is the correct choice over the 90-degree street elbow wherever a gradual pipe run redirection, diagonal routing around a structural element, or angled equipment connection approach is required — as opposed to the hard perpendicular corner suited to the 409 series. At 2", this fitting is commonly specified on pump discharge headers, large-diameter mainline offset sections, equipment connection approaches, and any 2" all-socket PVC assembly where a gradual directional change must originate immediately at a fitting hub.

Rated to approximately 280 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 2" socket hub per ASTM D2564 procedures, inserting fully and holding briefly for initial set. Apply solvent cement separately to the 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. Because the 45-degree offset establishes a diagonal pipe run direction off the hub face, plan both the spigot insertion orientation and the slip outlet direction before cementing either joint — both are fixed permanently once cement cures and the 45-degree angle means that downstream pipe alignment requires careful pre-planning relative to the upstream fitting hub orientation. Allow adequate cure time before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Provides a compact 45-degree offset directly off 2" socket-end tee branches, cross ports, coupling ends, and mainline fitting hubs in large-diameter agricultural and municipal irrigation systems where gradual directional offsets at fitting port locations allow diagonal routing around structural elements, grade changes, and equipment obstructions without the abrupt directional change of a 90-degree elbow
• Commercial Plumbing — Produces a tight 45-degree offset at socket fitting hubs, pump discharge connections, and distribution manifold ports in commercial building water distribution systems where angled pipe run approaches to equipment connections, wall penetrations, and structural constraints require a gentle directional change at the fitting hub face with minimum projection beyond the hub
• Pump Station Assemblies — Used on 2" pump discharge headers, bypass line offset connections, and equipment approach runs where a gradual 45-degree directional change must originate immediately at a socket fitting hub — a common requirement on pump discharge piping where the outlet orientation must angle away from the pump body toward the distribution header at a fixed offset angle without an intermediate nipple at the fitting connection point
• Industrial Process Piping — Provides a compact all-socket 45-degree offset at tee branches, manifold ports, and equipment connections on 2" process water distribution headers in water treatment, chemical processing, and manufacturing facilities where diagonal pipe routing, equipment approach angles, and close-quarters installation constraints require a gradual directional change directly at socket fitting hub faces
• Water Treatment & Aquaculture — Used at filter manifold offset connections, pump discharge angled approaches, and tank distribution assembly branch offsets where a 2" socket fitting must supply a diagonally routed pipe run with a 45-degree offset originating at the fitting hub face and NSF/ANSI 61 compliance is required throughout the all-socket assembly
• HVAC & Mechanical Systems — Produces compact 45-degree directional offsets directly off 2" socket fitting hubs on cooling tower supply headers, chilled water distribution assemblies, and chemically treated water system pipe runs within the Schedule 40 pressure class where gradual angled transitions at fitting hub locations are preferred over abrupt 90-degree turns for flow efficiency or spatial routing requirements
