Elbow, 45 Degree, Slip x Slip PVC Schedule 40 1" (417-010)

This 1" Schedule 40 PVC 45 Degree Elbow (Slip x Slip) provides a gradual 45-degree angular offset in all-socket PVC piping systems, accepting 1" 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, and light industrial applications where a shallower directional offset is preferred over a sharp 90-degree turn — producing lower flow resistance, reduced turbulence, and a more gradual pipe routing transition along 1" all-socket runs.

Both 1" slip socket ends accept 1" PVC pipe for permanent solvent-cement bonds, redirecting the pipe run 45 degrees between the inlet and outlet socket axes while preserving the full 1" interior diameter throughout the elbow body. The 45-degree geometry provides a less abrupt direction change than the 90-degree elbow (406 series) — making it the preferred choice wherever a pipe run must change direction gradually around a corner, grade change, obstacle, or routing constraint rather than making a sharp right-angle turn; the shallower turn reduces flow resistance and hydraulic losses at the elbow location, an advantage in high-flow irrigation mainlines, pump station piping, and process water headers where minimizing pressure drop at each direction change point contributes to overall system efficiency. Two 45-degree elbows can also be combined to produce an offset assembly that routes a pipe run around an obstacle while preserving the original pipe run orientation — a configuration that a single 90-degree elbow cannot replicate. At 1", this elbow is the highest-demand entry in the 417 series — appearing throughout irrigation mainline and sub-main routing assemblies, pump station discharge approach piping, commercial plumbing distribution header routing, and process water assembly pipe runs where 1" is the most widely specified all-socket PVC distribution diameter and gradual directional offsets are routinely needed at grade transitions, structural obstructions, and equipment approach routing points throughout the system layout. It should not be confused with the 406 series (90 Degree Slip x Slip Elbow at 1"), which produces a sharp right-angle turn, or with the 465 series (22-1/2 Degree Slip Elbow, confirmed at 1-1/2" in this catalog session), which provides an even shallower correction angle for minor routing adjustments.

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, 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 — Routes 1" PVC socket mainline and sub-main pipe runs around grade changes, structural obstructions, equipment layouts, and header routing transitions in agricultural and municipal irrigation systems where a gradual 45-degree angular offset preserves higher flow efficiency than a sharp 90-degree turn at each direction change point along the 1" all-socket distribution assembly
• Commercial Plumbing — Offsets 1" socket PVC distribution mains around wall structural elements, floor penetrations, and equipment approach obstructions in commercial building water distribution systems where a 45-degree transition produces a lower-profile, more gradual pipe routing adjustment than a right-angle turn at the direction change point
• Pump Station Assemblies — Provides gradual 45-degree approach transitions on 1" pump discharge headers, suction line routing, and bypass line assemblies in pump station installations where shallower turn angles reduce turbulence and pressure drop at each direction change point along the all-socket Schedule 40 PVC assembly
• Industrial Process Piping — Routes 1" socket process water distribution pipe runs, chemical feed lines, and equipment approach piping at gradual 45-degree offsets in water treatment, chemical processing, and manufacturing facilities where reducing hydraulic losses and turbulence at direction change points is a design priority throughout the all-socket assembly layout
• Water Treatment & Aquaculture — Used at gradual direction change points on 1" socket distribution headers, filter feed approach runs, pump suction routing, and recirculating system pipe layouts where NSF/ANSI 61 compliance and reduced hydraulic loss through shallow-angle direction changes are required throughout the all-socket assembly
• HVAC & Mechanical Systems — Routes 1" PVC socket pipe runs at 45-degree gradual offsets on cooling tower supply headers, chilled water distribution mains, and chemically treated water system pipe routing within the Schedule 40 pressure class where shallower turn angles reduce flow resistance and support more gradual pipe routing transitions at structural and equipment obstructions
