Elbow, 90 Degree Street, Spigot x Slip PVC Schedule 40 1" (409-010)

This 1" 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, fire suppression, and light industrial applications where a tight, low-profile 90-degree turn is required directly at a 1" 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" socket-end fitting — tee branch outlet, cross port, coupling end, elbow outlet, side outlet elbow port, 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" 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 highest-demand nominal 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", this elbow is the highest-demand entry in the 409 series, appearing throughout irrigation grid manifold assemblies, fire suppression branch header turns, commercial plumbing branch supply corner connections, and any 1" all-socket PVC installation where compact 90-degree turns must occur immediately at socket fitting hubs throughout the distribution network. It should not be confused with the 412-010 (MPT x FPT, all-threaded street elbow at 1"), 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 on both sides.

Rated to approximately 450 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" 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 compact 90-degree direction changes directly off tee branch outlets, cross ports, side outlet elbow ports, and manifold socket hubs in residential and light commercial irrigation grid assemblies where 1" is the standard lateral distribution and branch header diameter and fitting-hub-direct turns minimize projection and assembly footprint at every corner and branch turn throughout the grid layout
• Fire Suppression Systems — Creates compact right-angle direction changes directly off tee branches, cross ports, and header socket hubs in light-hazard and residential Schedule 40 PVC fire suppression systems where 1" is the dominant branch header and drop diameter and compact hub-direct turns reduce projection in tight ceiling plenum and wall cavity installations throughout the grid
• Commercial Plumbing — Provides tight, low-profile 90-degree turns 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 assembly projection beyond fitting hub faces at constrained 1" branch supply connection points
• Industrial Process Piping — Provides compact all-socket direction changes at tee branch outlets, manifold ports, and equipment socket connections in water treatment, chemical processing, and manufacturing facilities where close-quarters 1" socket fitting assemblies require 90-degree turns directly at fitting hub faces without intermediate pipe sections throughout the distribution layout
• Water Treatment & Aquaculture — Used at filter housing socket outlets, pump connection tee branches, recirculating system manifold ports, and distribution header 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 tight mechanical spaces requiring NSF/ANSI 61 compliance 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
