Elbow, 90 Degree, Slip x Slip PVC Schedule 40 3/4" (406-007)

This 3/4" Schedule 40 PVC 90 Degree Elbow (Slip x Slip) provides a right-angle direction change in all-socket PVC piping systems, accepting 3/4" PVC pipe at both socket ends for permanent solvent-cement bonds while redirecting the pipe run 90 degrees from the inlet axis. Constructed in white Schedule 40 PVC, it is the highest-demand full-size entry in the 406 series — the standard all-socket corner fitting at the dominant residential irrigation and light commercial distribution grid diameter — offering reliable performance at every direction change point throughout 3/4" irrigation mainline and lateral distribution assemblies, fire suppression grid headers, commercial plumbing branch supply headers, and light industrial process water socket runs wherever a full right-angle turn is required in an all-socket cemented PVC assembly.

Both 3/4" slip socket ends accept 3/4" PVC pipe for permanent solvent-cement bonds, redirecting the pipe run 90 degrees between the inlet and outlet socket axes while preserving the full 3/4" interior diameter through the elbow body. This full-size configuration — both ports at 3/4" with no size reduction at the turn — is the standard all-socket 90-degree elbow at this diameter and is distinct from the confirmed 406-101 (3/4" x 1/2" Reducing 90° Elbow), which shares the same 3/4" slip inlet but simultaneously reduces the pipe diameter to 1/2" at the outlet; 406-007 is the correct choice when the downstream pipe run must continue at the full 3/4" diameter rather than stepping down at the direction change point. At 3/4", this elbow appears at every corner, wall penetration, grade transition, and routing turn throughout residential landscape irrigation mainline and lateral distribution assemblies; in commercial irrigation sub-main routing around site features and structural elements; in fire suppression grid header routing around structural members and ceiling penetrations; and in commercial plumbing 3/4" branch supply header routing at wall penetrations and equipment approach turns — making this fitting the single most widely installed all-socket direction change component at the dominant residential and light commercial PVC assembly diameter.

Rated to approximately 480 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. Plan the outlet direction of the elbow before cementing the inlet 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 — Provides standard 90-degree direction changes at every corner, routing turn, wall penetration, grade transition, and obstacle navigation point throughout 3/4" all-socket irrigation mainline and lateral distribution assemblies in residential, light commercial, and agricultural irrigation systems — the highest-demand all-socket direction change fitting at the dominant residential irrigation grid diameter where corner turns are among the most frequent assembly requirements throughout the distribution layout
• Landscape Irrigation — Navigates 3/4" socket irrigation mainline and lateral runs around foundation corners, planting bed boundaries, paved surface edges, utility crossings, and grade transitions at full right-angle turns throughout residential and light commercial landscape irrigation grid assemblies where maintaining the full 3/4" pipe diameter through the direction change is required and no size reduction at the turn point is specified
• Fire Suppression Systems — Provides 90-degree direction changes on 3/4" socket grid branch lines, cross-main approach runs, and distribution header routing assemblies in light-hazard and commercial Schedule 40 PVC fire suppression systems where all-cemented construction is maintained at every direction change point throughout the 3/4" socket grid layout
• Commercial Plumbing — Redirects 3/4" socket PVC distribution mains and branch supply headers at wall penetrations, structural transitions, equipment connection approach points, and routing corners in commercial building water distribution systems where all-socket cemented construction is maintained throughout and the full 3/4" pipe diameter is preserved through each direction change point
• Industrial Process Piping — Provides 90-degree routing turns on 3/4" socket process water distribution runs, equipment feed approach lines, and service manifold supply pipe routing around equipment layouts, structural members, and installation constraints in water treatment, chemical processing, and manufacturing facilities where all-socket cemented construction is maintained at every direction change throughout the system
• Water Treatment & Aquaculture — Used at 90-degree direction change points on 3/4" socket distribution headers, filter approach lines, pump station suction and discharge routing, and recirculating system pipe routing where NSF/ANSI 61 compliance and a full right-angle direction change are required throughout the all-cemented assembly
