Elbow, 90 Degree Street, MPT x Slip PVC Schedule 40 1" (410-010)

This 1" Schedule 40 PVC MPT × Slip 90 Degree Street Elbow provides a right-angle directional change in a single mixed-connection fitting that combines a 1" male NPT threaded end with a 1" female slip socket — allowing the MPT end to thread directly into a female-threaded port while the slip socket outlet receives solvent-cemented PVC pipe at the 90° turn. The MPT end threads into any compatible 1" FPT port without an intermediate nipple or pipe section, while the slip socket end accepts standard 1" PVC pipe for solvent cement joining at the elbow outlet.

The "street" designation identifies the defining functional characteristic of this elbow. The MPT end can thread directly into an adjacent female-threaded fitting — a valve outlet, a female adapter, a threaded coupling, a tee branch port, or any fitting presenting a 1" FPT opening — eliminating the short nipple or pipe stub that a standard Slip × Slip elbow would require between the upstream threaded fitting and the elbow body. This direct fitting-to-fitting connection shortens the assembly, reduces total joint and component count, and allows a 90° direction change to occur at the exact face of the upstream threaded fitting without adding axial length between the fitting and the elbow.

The mixed MPT × Slip construction distinguishes the 410-010 from two related fittings at the same 1" Schedule 40 size. The 409-series Spigot × Slip 90° street elbow (previously written at 409-020 at 2") accomplishes the same direct fitting-to-fitting connection advantage — but at the slip socket upstream connection type rather than at a threaded port; the 409-series spigot inserts into an upstream socket rather than threading into an upstream FPT port. When the upstream connection is a 1" FPT port, the 410-010 MPT end is correct. When it is a 1" slip socket, the 409-series applies. The 406-series all-socket Slip × Slip 90° elbow requires a pipe section on both sides — it cannot make the direct fitting-to-fitting connection that the street elbow configuration provides at either a threaded or socket upstream connection.

At 1", the 410-010 serves the most prevalent commercial and residential pipe size across Schedule 40 systems. One-inch NPT threaded ports appear on the broadest range of standard irrigation control valve bodies, pool and spa pump discharge ports, commercial plumbing backflow preventer outlets, strainer body discharges, valve body outlets, and equipment nozzles in residential and commercial facilities. Wherever any of these 1" FPT-ported components must simultaneously transition to a solvent-cemented pipe run AND change direction at 90° at the component outlet, the 410-010 provides the most compact single-fitting solution — the MPT end threads into the component port and the slip socket routes the cemented downstream pipe at 90° without an intermediate nipple, coupling, or standard elbow in between.

The 410-010 differs from the 410-020 (2" MPT × Slip, previously written) in pipe size and the application contexts that come with it. The 410-020 serves the large-bore 2" pump station, irrigation mainline, and commercial plumbing primary distribution contexts where a compact direction change at a 2" FPT connection is required. The 410-010 serves the much broader and higher-frequency population of 1" FPT connections across residential and commercial system types — irrigation valve stations, pool and spa equipment pad connections, commercial plumbing valve assemblies, and compact pump and equipment connection clusters where 1" is the standard connection size.

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 seize. 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, pool and spa, commercial plumbing, water treatment, and light industrial applications at 1". Apply PTFE tape or compatible thread sealant to the MPT threads before engaging any FPT port. Hand-tighten plus one to two turns — do not over-torque into PVC or metal female threads. For the slip socket end, clean and dry the pipe end and socket interior before application. Apply purple PVC primer to both mating surfaces, then apply a uniform coat of Schedule 40 PVC solvent cement to both before inserting the pipe with a slight quarter-turn twist, holding firmly for 30 seconds. The MPT end must be fully made up into the receiving FPT port before cementing the slip socket end — making up the threaded end first preserves rotational freedom to align the slip socket outlet direction before committing the cemented joint. Confirm the 90° turn direction and the slip socket outlet orientation before making up either joint. Allow full cure time per the cement manufacturer's guidelines before pressurizing. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Irrigation Control Valve & Filter Station Connections — The defining and highest-frequency application for the 1" Schedule 40 MPT × Slip 90° street elbow: threads directly into a 1" FPT irrigation control valve outlet, filter station FPT discharge, or backflow preventer FPT connection and simultaneously routes the downstream cemented pipe run at 90° — eliminating the nipple between the valve outlet and a standard 90° elbow in irrigation valve box and pump station assemblies where compact outlet piping is a practical design requirement at the most prevalent 1" control component connection size
• Pool, Spa & Aquaculture Equipment Connections — Threads into a 1" FPT pump discharge port, filter head outlet, heater FPT connection, or valve body outlet and simultaneously routes the cemented pipe run at 90° in pool and spa equipment pad piping where compact outlet geometry at 1" FPT equipment ports reduces the equipment pad footprint and minimizes the fitting assembly between the equipment port and the downstream cemented pipe run
• Commercial Plumbing Valve & Backflow Preventer Connections — Provides a direct 90° routing change at 1" FPT valve outlet connections, backflow preventer FPT outlets, pressure reducing valve outlets, and pressure gauge supply branches in commercial building water distribution and mechanical room systems where the 1" cemented downstream pipe must change direction immediately at the threaded component face without an intermediate nipple
• Pump Station & Equipment Outlet Routing — Threads into a 1" FPT pump discharge connection, equipment nozzle, or strainer body outlet and routes the downstream 1" cemented pipe at 90° in residential and commercial pump station outlet assemblies and mechanical equipment pad connections where the compact direct-port-to-elbow geometry reduces the outlet piping assembly length and fitting count
• Water & Wastewater Treatment — Routes 1" Schedule 40 PVC solvent-welded secondary distribution and equipment approach piping through 90° turns while threading directly into female-threaded pump ports, valve outlets, and equipment nozzle connections in light-duty municipal and industrial water treatment facilities where the compact street elbow geometry reduces fitting count at 1" FPT port connection and direction change positions
• Commercial & Residential Irrigation — Manifold & Zone Header Connections — Threads into 1" FPT manifold outlet ports, zone header valve connections, and filter station discharge fittings while simultaneously routing the downstream cemented lateral or zone supply pipe at 90° in residential and commercial irrigation manifold assemblies where compact connection geometry within valve boxes and manifold enclosures benefits from the direct-port-to-elbow connection of the MPT street elbow
• Light Industrial Process Piping — Provides a 90° directional change and threaded-to-cemented system transition at 1" FPT process valve outlets, equipment nozzle connections, and strainer body discharge ports in light industrial and chemical handling Schedule 40 systems where the downstream 1" cemented pipe must simultaneously change direction and transition from the threaded component interface to the solvent-welded pipe system at the same fitting position
