Elbow, 90 Degree, Slip x Slip PVC Schedule 40 1-1/4" (406-012)

This 1-1/4" Schedule 40 PVC 90 Degree Elbow (Slip x Slip) provides a full-size right-angle direction change in all-socket PVC piping systems, accepting 1-1/4" PVC pipe at both socket ends for permanent solvent-cement bonds while maintaining full mainline diameter through the elbow body. Constructed in white Schedule 40 PVC, it offers reliable performance in commercial plumbing, irrigation, pump station assemblies, and light industrial applications where a corrosion-resistant, all solvent-cement right-angle turn is required along a 1-1/4" socket pipe run without reducing flow capacity or introducing threaded interfaces at the direction change point.

Both 1-1/4" slip socket ends accept 1-1/4" PVC pipe for permanent solvent-cement bonds, redirecting the pipe run 90 degrees between the inlet and outlet socket axes while preserving the full 1-1/4" interior diameter throughout the elbow body. This full-size configuration should not be confused with the reducing 406 series variants at larger inlet sizes confirmed in this catalog session — the 406-012 maintains a consistent 1-1/4" socket on both sides for contractors who need a full-capacity right-angle turn along a 1-1/4" mainline run without any reduction at the elbow. At 1-1/4", this elbow is a widely specified intermediate direction change fitting in the Schedule 40 PVC catalog — appearing throughout irrigation mainline and sub-main routing assemblies, pump station discharge and suction piping, commercial plumbing distribution headers, process water assemblies, and light industrial fluid handling systems where 1-1/4" pipe runs must change direction at right angles while maintaining the full intermediate mainline flow capacity through the turn. At this intermediate diameter, the 406-012 is particularly common in secondary distribution headers and sub-main routing assemblies that branch off 1-1/2" or 2" primary mains and require direction changes throughout their routed layout.

Rated to approximately 370 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 elbows in moisture-prone or chemically active environments. NSF/ANSI 61 listing confirms suitability for potable water contact, including use in drinking water distribution and treatment systems.

Apply solvent cement to both the pipe end and fitting socket at each port per ASTM D2564 procedures, using a primer appropriate for the pipe and fitting schedule. Insert pipe fully into each socket and maintain a quarter-turn during assembly for even cement distribution across the joint surface. Plan the outlet direction of the elbow before cementing the first joint — the downstream pipe run alignment is established when the inlet 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 — Changes direction on 1-1/4" PVC socket sub-main and secondary distribution runs around grade changes, structural obstructions, equipment layouts, and header routing transitions in agricultural and municipal irrigation systems where all-socket construction is maintained throughout and full intermediate mainline flow capacity must be preserved through the right-angle turn at each direction change point along the 1-1/4" sub-main assembly
• Commercial Plumbing — Redirects 1-1/4" socket PVC distribution mains at wall penetrations, structural transitions, equipment connection approaches, and riser offsets in commercial building water distribution systems where all-socket PVC construction is specified and a full-size right-angle turn maintains complete intermediate mainline flow capacity at the direction change point
• Pump Station Assemblies — Provides right-angle direction changes on 1-1/4" pump discharge headers, suction line approaches, and bypass line routing in pump station installations where 90-degree turns at full 1-1/4" diameter are required along all-socket Schedule 40 PVC assemblies at pump body connections, valve clusters, and header routing transitions
• Chemical Handling — Performs reliably at right-angle direction change points in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, providing full-size 90-degree turns within all-socket PVC chemical distribution, dosing, and feed assemblies at 1-1/4" line sizes where the intermediate diameter serves dedicated chemical distribution and feed runs
• Water Treatment & Aquaculture — Used at full-size 90-degree direction change points on 1-1/4" socket distribution headers, filter feed mains, pump suction approach lines, and recirculating system pipe routing where NSF/ANSI 61 compliance and full-diameter flow capacity through the elbow are required throughout the all-socket assembly
• HVAC & Mechanical Systems — Redirects 1-1/4" PVC socket pipe runs at 90-degree direction change points on cooling tower supply headers, chilled water distribution mains, and chemically treated water system pipe routing within the Schedule 40 pressure class where all-socket construction is preferred and full intermediate mainline diameter must be maintained through each direction change
