90 Degree Street Elbow, Spigot x Slip PVC Schedule 40 2" (409-020)

This 2" Schedule 40 PVC 90 Degree Street Elbow provides a right-angle directional change in a single all-cement fitting that combines a 2" spigot end with a 2" female slip socket — allowing the spigot end to insert directly into the female socket of an adjacent fitting while the slip socket outlet receives solvent-cemented PVC pipe at the 90° turn. Both connections are permanent, chemically fused solvent-cemented joints; no threaded interface is present at either end of the fitting.

The "street" designation identifies the defining functional characteristic of this elbow. A standard Slip × Slip 90° elbow (406-series) requires a section of PVC pipe on both sides — pipe enters one socket, the elbow changes direction, and pipe exits the other socket. The street elbow's spigot end changes this dynamic on the inlet side: the spigot — a male plain end whose outer diameter matches standard 2" PVC pipe — inserts directly into the female socket of any adjacent fitting without a pipe section between them. When a tee branch socket, a coupling socket, a cross port, a female adapter socket, or any other fitting presenting a female slip opening is the upstream connection, the street elbow's spigot inserts directly into that socket and changes direction immediately at the face of the fitting. This direct fitting-to-fitting connection eliminates the short pipe stub or nipple that a standard elbow would require between the upstream socket and the elbow body.

The all-cement Spigot × Slip configuration distinguishes the 409-020 from its street elbow counterpart the 410-020 (MPT × Slip, previously written). Both are street elbows at the same 2" size and schedule — both accomplish direct fitting-to-fitting connection at the inlet and continue into solvent-welded pipe at the outlet. The distinction is the male end type: the 409-020 spigot end inserts into and cements within a slip socket; the 410-020 MPT end threads into a female-threaded FPT port. When the upstream connection is a female slip socket opening — the most common fitting connection type in a solvent-welded PVC system — the 409-020 is the correct street elbow selection. When the upstream port is female-threaded, the 410-020 applies. Both eliminate the intermediate pipe stub; the upstream connection type is the sole selection criterion between them.

The compact-assembly advantage is the primary application driver for the street elbow in any PVC system. At 2", this advantage is most pronounced at fitting clusters, equipment connection assemblies, and tight piping layouts where achieving a 90° direction change immediately at the face of a tee branch, coupling, or adapter socket eliminates an otherwise unavoidable pipe section between the fitting body and the elbow. In constrained mechanical spaces — pump pads, equipment rooms, filter station piping clusters — removing even a short pipe stub from the assembly reduces the overall fitting cluster footprint and simplifies the layout. In systems where the direction change must occur at the exact position of an upstream socket — such as a tee branch outlet that must immediately route the branch pipe at 90° to clear an obstruction — the street elbow is the only single-fitting solution that accomplishes both the branch connection and the direction change simultaneously.

At 2", this elbow serves applications where the pipe size carries meaningful flow volume — irrigation submain branches, pump station outlet routing, filter station connections, commercial plumbing distribution branches, and pool and spa recirculation system connections. At each of these 2" fitting cluster positions where a 90° direction change is required at a slip socket face, the 409-020 provides the most compact, lowest-joint-count solution available.

Manufactured in white Schedule 40 PVC, this elbow delivers reliable performance across residential, commercial, and light industrial piping applications. PVC's resistance to acids, bases, salts, chlorine, and common process fluids provides long service life where metal street elbows would corrode or scale. NSF/ANSI 61 and NSF/ANSI 14 listings confirm suitability for potable water contact.

Rated to 280 psi at 73°F, this fitting handles standard pressure service across irrigation, commercial plumbing, pool and spa, and process piping applications at 2". For installation, the spigot end must be inserted and cemented into the receiving upstream socket before the downstream slip socket pipe joint is made — this sequence preserves rotational freedom to align the spigot in the correct angular orientation before committing the joint. Clean and dry the spigot exterior and receiving socket interior thoroughly before the upstream joint; apply purple PVC primer to both surfaces; apply medium-body Schedule 40 PVC solvent cement to both the spigot exterior and socket interior and insert with a slight quarter-turn twist, holding firmly for 30 seconds. Before cementing the upstream joint, confirm the 90° outlet socket is correctly oriented toward the downstream pipe run — this spatial orientation is set permanently at the upstream joint and cannot be adjusted once the cement cures. Then make the downstream slip socket pipe joint following the same primer-and-cement procedure. Allow full cure time per the cement manufacturer's temperature and humidity guidelines before pressurizing the system. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Fitting Cluster & Compact Piping Assemblies — Inserts directly into the female slip socket of an upstream tee branch outlet, coupling socket, cross port, or female adapter socket and simultaneously routes the connected pipe run through a 90° turn at the fitting face — the defining application for the all-cement spigot street elbow wherever a direction change must occur immediately at a slip socket position without an intermediate pipe section in congested 2" Schedule 40 PVC piping assemblies
• Irrigation & Agriculture — Provides a compact direction change at 2" slip socket positions on tee branch outlets, mainline coupling sockets, and distribution fitting ports in commercial and agricultural irrigation systems where the branch or main run must change direction immediately at the slip socket face — eliminating the pipe stub between the upstream socket fitting and the standard elbow in tight above-grade and buried piping layouts
• Pump Station & Equipment Routing — Inserts into a 2" female adapter socket or coupling socket at pump discharge or suction piping connections and routes the pipe run through a 90° turn at the socket face in compact pump station outlet assemblies where the direction change must occur at the equipment connection fitting without axial extension from an intermediate pipe section
• Commercial Plumbing — Changes direction immediately at 2" slip socket positions on tee branches, couplings, and distribution fittings in mechanical room and building water supply systems where the compact fitting-to-fitting geometry of the spigot street elbow preserves clearance and reduces assembly footprint at right-angle routing transitions in constrained piping spaces
• Filter Station Piping — Connects directly into 2" slip socket inlet and outlet ports on filter vessel adapters, backwash fitting sockets, and chemical treatment connection sockets while simultaneously routing the connected pipe at 90° in filter station piping assemblies where compact layouts at the filter vessel connections benefit from the elimination of nipple-and-standard-elbow assemblies at direction change points
• Pool, Spa & Aquaculture — Inserts into 2" female slip socket positions on pump discharge adapters, filter head socket ports, valve body sockets, and manifold fitting sockets while routing the connected pipe run through a 90° turn at the socket face in pool and spa equipment connection assemblies and aquatic facility recirculation system piping where mechanical pad space constraints make direct socket-to-elbow connections preferable to standard elbow and pipe stub assemblies
• Water & Wastewater Treatment — Provides a compact 90° direction change at 2" slip socket positions on distribution tee branches, process header coupling sockets, and equipment connection adapter ports in water treatment facility piping where the all-cement construction maintains full solvent-welded system integrity through the direction change and the spigot end eliminates the short pipe stub at the upstream socket fitting
