Elbow, 90 Degree, Slip x Slip PVC Schedule 40 1" (406-010)

This 1" Schedule 40 PVC 90 Degree Elbow (Slip x Slip) provides a full right-angle direction change in all-socket PVC piping systems, accepting 1" PVC pipe at both socket ends for permanent solvent-cement bonds while redirecting the pipe run 90 degrees without reducing the inline diameter. Constructed in white Schedule 40 PVC, it offers reliable performance in irrigation mainline routing, fire suppression grid assemblies, commercial plumbing branch supply distribution, and light industrial process water socket systems where a right-angle turn is required along a 1" all-socket pipe run without a simultaneous size reduction at the direction change point.

Both 1" slip socket ends accept 1" 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" interior diameter throughout the elbow body. The full-size configuration — both ends 1" slip, same diameter throughout — is the correct choice when the upstream and downstream pipe run must both remain at 1" at the direction change point; it should not be confused with the 406-130 (1" x 1/2" Reducing 90 Degree Elbow, confirmed in this catalog session), which shares the same 1" slip inlet but simultaneously steps the outlet down to 1/2" while changing direction — the correct choice only when both a 90-degree turn and a size reduction from 1" to 1/2" must occur at the same fitting location. At 1", the full-size 90 degree elbow is among the highest-demand direction change fittings in the catalog — appearing throughout residential and commercial irrigation mainline routing assemblies where 1" socket pipe runs must navigate foundation corners, grade transitions, buried service obstructions, and routing changes throughout the mainline layout; in fire suppression grid header assemblies where 1" branch lines must turn at structural elements and coverage boundaries; in commercial plumbing branch supply headers where 1" socket runs must change direction at wall penetrations and structural transitions; and in light industrial process water socket distribution assemblies where 1" pipe runs must navigate equipment layouts and installation constraints. The complete 1" direction change elbow family in this catalog session spans the full-size 406-010 (no size reduction, turn only) and the reducing 406-130 (simultaneous 1" to 1/2" size reduction and 90-degree turn) — together covering both direction-change-only and turn-and-reduce applications at the 1" inlet size throughout all-socket PVC assemblies.

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 elbows in moisture-prone or chemically active environments. NSF/ANSI 61 listing confirms suitability for potable water contact.

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 — Navigates 1" PVC socket mainline and lateral distribution runs around foundation corners, grade transitions, buried service conflicts, and routing obstacles in residential and commercial landscape irrigation systems where a full right-angle direction change at the 1" mainline or primary lateral diameter is required without a simultaneous size reduction at the elbow location throughout the all-socket mainline routing layout
• Fire Suppression Systems — Provides full right-angle direction changes on 1" socket branch lines, grid headers, and lateral distribution runs at structural elements, ceiling penetrations, coverage boundaries, and routing constraints in light-hazard and residential Schedule 40 PVC fire suppression systems where the 1" grid header diameter must be maintained through the elbow without reduction
• Commercial Plumbing — Redirects 1" socket PVC distribution mains and branch supply headers at wall penetrations, structural transitions, panel approach routes, and equipment connection offsets in commercial building water distribution systems where a full 90-degree turn at the 1" branch supply diameter is required without size reduction at the direction change point
• Industrial Process Piping — Navigates 1" socket process water distribution runs, equipment feed approach lines, and service manifold supply headers around equipment layouts, structural members, and installation constraints in water treatment, chemical processing, and manufacturing facilities where a full right-angle direction change at the 1" distribution diameter is required without reducing the pipe run at the elbow location
• Pump Station Assemblies — Changes direction on 1" socket pump station discharge headers, suction line approach runs, and bypass line pipe sections at compact routing turns, structural constraints, and equipment connection approach points where a full 90-degree direction change at the 1" socket pipe diameter must occur without size reduction throughout the pump station piping layout
• Water Treatment & Aquaculture — Used at 90-degree routing transition points on 1" all-socket distribution headers, filter approach lines, and recirculating system pipe runs where NSF/ANSI 61 compliance and a full right-angle direction change at the 1" distribution diameter are required without size reduction at the elbow location throughout the all-cemented assembly
