Reducing Elbow, 90 Degree, Slip x Slip PVC Schedule 40 1-1/2" x 1" (406-211)

This 1-1/2" x 1" Schedule 40 PVC 90 Degree Reducing Elbow (Slip x Slip) combines a right-angle direction change and an inline pipe size reduction into a single solvent-cement fitting, eliminating the need for a separate standard elbow and reducer coupling in the same assembly location. Constructed in white Schedule 40 PVC, it offers reliable performance in commercial plumbing, irrigation, and light industrial piping applications where a compact, corrosion-resistant combination fitting reduces overall fitting count and minimizes potential leak points in the completed system.

The 1-1/2" slip socket on the larger inlet end and the 1" slip socket on the smaller outlet end each accept their respective PVC pipe sizes for permanent solvent-cement bonds. The 90-degree body geometry redirects flow perpendicular to the incoming pipe run while simultaneously stepping down pipe diameter — a configuration well-suited to pump outlets transitioning to smaller branch distribution lines, equipment connections where a 1-1/2" supply main feeds a dedicated 1" service run, and space-constrained installations where combining two functions into one fitting preserves clearance and simplifies the assembly. The 1-1/2" to 1" step-down is a modest 1.5:1 reduction that preserves substantial flow capacity through the outlet, making this elbow a practical choice wherever a 1-1/2" socket main must turn 90 degrees and connect to a 1" downstream run at the same assembly point — delivering both the direction change and the diameter reduction without the additional joint, pipe section, and fitting space that a standard elbow plus separate reducer coupling would require.

Rated to 330 psi at 73°F (governed by the 1-1/2" inlet end), 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 on each side 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. Allow adequate cure time before pressurizing the system, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Irrigation & Water Distribution — Transitions 1-1/2" PVC supply mains around corners while simultaneously stepping down to 1" lateral branch lines at zone headers, pump discharge assemblies, and field distribution points in agricultural and municipal irrigation systems where a moderate direction-change-and-reduction combination fitting reduces assembly complexity at high-frequency branch turn locations
• Commercial Plumbing — Redirects and reduces 1-1/2" supply mains to 1" branch service lines at equipment connections, riser transitions, and fixture supply points in commercial building water distribution systems where combining the direction change and size reduction into a single fitting simplifies assembly in congested mechanical spaces
• Industrial Process Piping — Combines direction change and diameter reduction at pump outlets, equipment inlets, and process water distribution headers in water treatment, chemical processing, and manufacturing facilities where fitting count and assembly footprint are design constraints at 1-1/2"-to-1" transition points
• Water Treatment & Aquaculture — Used at pump discharge connections, filter feed transitions, and recirculating system headers where a 90-degree turn and a moderate pipe size reduction occur at the same assembly point and a single combination fitting is preferred over a standard elbow and separate reducer coupling
• Chemical Handling — Provides a corrosion-resistant, combined direction-change and size-reduction fitting in systems conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings, particularly in compact equipment enclosures and chemical distribution assemblies where minimizing fitting count at 1-1/2"-to-1" turn-and-reduce locations is advantageous
• HVAC & Mechanical Systems — Redirects and reduces 1-1/2" pipe runs to 1" branch connections at equipment feed points, panel penetrations, and distribution header turns on cooling tower supply assemblies, chilled water branch lines, and chemically treated water systems within the Schedule 40 pressure class
