90 Degree Street Elbow, MPT x Slip PVC Schedule 40 2" (410-020)

This 2" Schedule 40 PVC 90 Degree Street Elbow provides a right-angle directional change in a single fitting that combines a 2" male NPT threaded end with a 2" female slip socket — allowing one end to thread directly into a female-threaded port while the other receives solvent-cemented PVC pipe at the elbow outlet. The MPT end threads into any compatible 2" FPT port without an intermediate nipple or pipe section, while the slip socket end accepts standard 2" PVC pipe for solvent cement joining at the 90° outlet.

The "street" designation is the defining characteristic of this elbow and the primary reason it is specified over a standard slip × slip elbow in the applications it serves. A standard slip × slip elbow requires a pipe section or nipple on both sides of the fitting — pipe on the inlet, pipe on the outlet. The street elbow's 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 an FPT opening — eliminating the short nipple or pipe stub that a standard elbow would require between the two fittings. This direct fitting-to-fitting connection is the practical advantage: it shortens the assembly, reduces the total fitting and joint count, and allows a 90° direction change to be made at the exact face of the upstream threaded fitting without adding axial length to the assembly.

This geometry makes the street elbow particularly valuable in constrained installations where there is insufficient clearance for a nipple between two fittings, at valve outlets where the direction change must occur immediately at the valve body, and in compact pump and equipment connections where minimizing the overall footprint of the piping assembly is a design priority. At 2", these compact-assembly applications appear regularly at pump station outlet routing, valve body directional changes, filter station connection piping, and irrigation mainline equipment connections where the 2" pipe size carries substantial flow volume and space efficiency at the fitting cluster is a practical consideration.

The mixed MPT × Slip construction places the 410-020 in a distinct position among Schedule 40 90° elbows at 2". The 406-series all-socket elbow serves fully solvent-welded pipe systems where both sides of the turn are cemented pipe ends. The 408-series all-threaded elbow serves fully threaded systems where both sides receive nipples or MPT fittings. The 410-020 street elbow bridges the two — the MPT end interfaces with the threaded portion of a hybrid assembly or a threaded upstream fitting, while the slip socket end continues into the solvent-welded pipe system at the elbow outlet. This mixed construction makes it the natural fitting at the transition point between a threaded component and a solvent-welded pipe run that must also change direction at the same point — accomplishing both the thread-to-socket transition and the 90° directional change in a single compact fitting.

Manufactured in white Schedule 40 PVC, this elbow delivers reliable performance across residential, commercial, and light industrial piping applications at this large-bore pipe size. PVC's resistance to acids, bases, salts, chlorine, and common process fluids provides long service life in environments where metal street elbows would corrode, seize on threads, or require replacement from corrosion-driven joint degradation. NSF/ANSI 61 and NSF/ANSI 14 listings confirm suitability for potable water contact.

For the MPT end, apply PTFE tape or compatible thread sealant to the male 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 medium-body Schedule 40 PVC solvent cement to both the pipe end and socket interior before joining. Insert the pipe with a slight quarter-turn twist and hold firmly for 30 seconds. Note that the MPT end must be fully made up into the receiving FPT port before cementing the slip socket end — cementing the socket end first constrains the ability to thread and align the MPT end properly. 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 temperature and humidity guidelines before pressurizing. Apply published pressure derating factors for service temperatures above 73°F.

Industries & Applications:

• Pump Station & Equipment Outlet Routing — Threads directly into a 2" FPT pump discharge port, valve outlet, or equipment nozzle and simultaneously routes the connected pipe run through a 90° turn at the fitting face — eliminating the nipple that a standard slip × slip elbow would require between the pump port and the elbow body in compact pump station outlet assemblies where space at the equipment connection is limited
• Irrigation & Agriculture — Provides a direct fitting-to-fitting 90° direction change at 2" FPT valve outlet ports, filter station connection bodies, and mainline equipment connections in commercial and agricultural irrigation systems where the street elbow's ability to thread into the valve or fitting and immediately change direction reduces the assembly footprint at major equipment connection points
• Commercial Plumbing — Changes direction immediately at a 2" FPT female adapter, valve outlet, or threaded coupling without an intermediate nipple in commercial building water supply, mechanical room equipment connections, and utility chase piping where clearance constraints or assembly compactness requirements make the standard slip × slip elbow with a nipple impractical at the direction change point
• Filter Station Piping — Connects directly to 2" FPT filter vessel inlet and outlet ports, backwash valve bodies, and chemical treatment connection ports while simultaneously routing the connected pipe run through a 90° turn in filter station inlet and outlet assemblies where compact piping layouts at the filter vessel connections benefit from the street elbow's direct port-to-elbow connection
• Valve & Fitting Direct Connections — Used wherever a 90° direction change must be made immediately at the face of a female-threaded fitting — eliminating the short nipple between the fitting and the elbow that a standard slip × slip elbow requires; particularly valuable in retrofit and repair situations where insufficient clearance exists for a nipple between the upstream FPT fitting and the direction change point
• Pool, Spa & Aquaculture — Connects directly to 2" FPT pump discharge ports, filter head inlets, heater connection bodies, and valve outlets while routing the pipe run through a 90° turn in pool, spa, and aquatic facility equipment connection assemblies where compact mechanical pad layouts make direct fitting-to-fitting connections preferable to nipple-and-elbow assemblies
• Water & Wastewater Treatment — Provides a compact direction change at 2" FPT equipment connection ports, process valve outlets, chemical treatment vessel connections, and pump flange adapters in water treatment facility piping where the MPT end threads into the equipment fitting and the slip socket routes the downstream pipe at 90° in a single compact component
