Elbow, 90 Degree Street, Spigot x Slip PVC Schedule 40 1/2" (409-005)

This 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 irrigation, instrument distribution, chemical handling, and light industrial applications where a tight, low-profile 90-degree turn is required directly at a 1/2" 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 1/2" 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 1/2" 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 street elbow concept at the smallest standard socket pipe size in the PVC fitting catalog — where the spigot inlet cements directly into a socket fitting hub without an intermediate pipe section, eliminating one joint, shortening the assembly projection beyond the fitting face, and reducing the overall fitting count at every direction change that originates directly at a socket hub. At 1/2", this elbow is most commonly encountered in small-bore instrument manifold assemblies and distribution systems where close-quarters 90-degree turns off cross and tee fitting hubs must minimize projection; in compact chemical injection and dosing distribution assemblies where 1/2" all-socket construction is maintained throughout and fitting footprint at direction changes is constrained; in micro-irrigation and drip system lateral headers where 1/2" socket pipe runs must change direction compactly at fitting hub locations; and in light industrial process water service assemblies where small-bore 1/2" socket distribution runs require hub-direct 90-degree turns with minimum joint count and assembly length at each direction change point. It should not be confused with the 412-005 (MPT x FPT, all-threaded street elbow at 1/2", confirmed in this catalog session), which threads into a female port rather than cementing into a socket hub, or with the standard Slip x Slip 406 series elbow, which requires a pipe section between the upstream fitting hub and the elbow inlet.

Rated to approximately 600 psi at 73°F — the highest confirmed pressure rating in the 409 series, reflecting the elevated pressure capacity of small-bore Schedule 40 PVC socket fittings — this elbow is suited for standard commercial and light industrial pressure service well within its pressure class. Its PVC composition provides excellent resistance to corrosion, scale, chlorinated water, and a broad range of chemical exposures. 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 1/2" pipe end exterior and the fitting's slip socket interior before inserting the pipe fully and maintaining a quarter-turn during assembly. 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:

• Drip & Micro-Irrigation Systems — Produces compact 90-degree direction changes directly off tee branch outlets, cross ports, and manifold socket hubs in small-bore 1/2" drip irrigation lateral header assemblies and micro-irrigation distribution systems where hub-direct turns minimize projection at each direction change point throughout compact grid-layout and manifold-style drip zone distribution assemblies
• Chemical Handling & Injection — Provides tight, low-profile 90-degree turns directly off socket fitting hubs in 1/2" all-socket chemical dosing manifolds, injection distribution assemblies, and chemical feed lateral headers conveying acids, caustics, fertilizer solutions, and other chemically aggressive fluids where compact hub-direct direction changes reduce fitting count and assembly projection throughout the small-bore all-socket chemical distribution layout
• Instrument & Process Piping — Creates compact all-socket direction changes directly at tee branch outlets, cross ports, and manifold socket hubs in 1/2" instrument supply distribution assemblies, sample system lateral headers, and small-bore process fluid distribution lines in manufacturing, laboratory, and water treatment facilities where close-quarters hub-direct 90-degree turns minimize assembly footprint at each direction change point throughout the small-bore socket layout
• Commercial Plumbing — Provides compact right-angle turns at socket fitting hubs, tee branch outlets, and valve body socket ports in commercial building small-bore water distribution systems where 1/2" all-socket PVC construction is specified and a hub-direct 90-degree turn reduces assembly projection at constrained small-bore direction change points throughout the branch supply layout
• Water Treatment & Aquaculture — Used at filter housing socket outlets, chemical dosing lateral manifold hub ports, recirculating system small-bore distribution fitting hubs, and compact instrument supply assembly direction change points where a 90-degree turn must occur immediately at the socket fitting hub face with minimum projection in compact equipment enclosures and small-bore mechanical assemblies with NSF/ANSI 61 compliance required throughout
• HVAC & Mechanical Systems — Produces compact 90-degree direction changes directly off 1/2" socket fitting hubs on small-bore cooling tower supply laterals, chilled water service branch tee hub outlets, and chemically treated water system small-bore service line socket fitting ports within the Schedule 40 pressure class where tight spatial clearances at 1/2" fitting hub locations favor the spigot street elbow over a standard slip elbow plus intermediate pipe section
