Elbow, 90 Degree Side Outlet, Slip x Slip x Slip PVC Schedule 40 1" (413-010)

This 1" Schedule 40 PVC 90 Degree Side Outlet Elbow (Slip x Slip x Slip) combines a right-angle direction change and a perpendicular branch outlet into a single three-port solvent-cement fitting, providing a three-dimensional piping junction that cannot be replicated with a standard elbow or tee alone. Constructed in white Schedule 40 PVC, it offers reliable performance in commercial plumbing, irrigation, and light industrial applications where a pipe run must simultaneously change direction and branch off in a third plane — reducing fitting count, minimizing potential leak points, and simplifying assembly in spatially complex piping layouts.

Two of the three 1" slip socket ports form the 90-degree inline turn — functioning identically to a standard elbow along the primary pipe run axis. The third port exits perpendicular to the plane formed by those two turn ends, providing a branch outlet in a direction that neither a standard elbow nor a tee can achieve without additional fittings and nipples. At 1", this fitting is among the most versatile sizes in the 413 series — appearing throughout irrigation manifold corner branch points, fire suppression grid headers, commercial plumbing riser assemblies, and process water distribution layouts where 1" pipe serves as the primary distribution diameter and three-dimensional branching at corner locations is a recurring layout requirement. This three-dimensional geometry makes the side outlet elbow the correct fitting wherever a branch must exit toward a wall, ceiling, or floor simultaneously with a direction change along the main run, consolidating what would otherwise require a corner elbow plus an adjacent tee and connecting nipple into a single compact body.

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 fittings 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. Because this fitting establishes pipe orientation in three planes simultaneously, all downstream pipe runs and fitting alignments must be planned and staged before cementing begins — orientation 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 — Used at grid-layout manifold corners in agricultural and municipal irrigation systems where a 1" supply header must simultaneously turn 90 degrees and branch off in a third direction to serve a lateral zone line or dedicated service connection, replacing a corner elbow and adjacent tee with a single compact fitting body at the most common distribution pipe diameter
• Fire Suppression Systems — Provides a three-dimensional branch point at header corners in Schedule 40 PVC sprinkler systems, allowing a 1" branch drop to exit toward a sprinkler head location simultaneously with a 90-degree turn along the distribution header — a particularly common requirement in grid-layout residential and light commercial fire suppression systems where 1" pipe is the standard branch header diameter
• Commercial Plumbing — Provides a three-plane branch point at structural corners, wall intersections, and equipment enclosure layouts in commercial building water distribution systems where 1" pipe routing constraints require branching in three directions from a single fitting rather than a multi-fitting assembly at corner locations
• Industrial Process Piping — Serves as a three-dimensional junction fitting in 1" process water distribution assemblies, cooling water headers, and rinse station piping layouts in light industrial and manufacturing facilities where spatial constraints at corner locations require simultaneous direction change and perpendicular branching at this common intermediate service diameter
• Water Treatment & Aquaculture — Used in recirculating system manifolds, filter feed headers, and tank distribution assemblies at corner branch points where a 90-degree turn and a perpendicular outlet must occur at the same 1" pipe location and NSF/ANSI 61 compliance is required throughout the system
• HVAC & Mechanical Systems — Provides a three-plane piping junction at header corners and equipment enclosure boundaries on 1" chilled water distribution systems, cooling tower supply lines, and chemically treated water assemblies where Schedule 40 PVC pressure ratings are appropriate and spatial constraints favor a single combination fitting over a multi-piece corner and branch assembly
