Elbow, 90 Degree, Slip x Slip PVC Schedule 40 1/2" (406-005)

This 1/2" Schedule 40 PVC 90 Degree Elbow (Slip x Slip) provides a right-angle direction change in all-socket PVC piping systems, accepting 1/2" PVC pipe at both socket ends for permanent solvent-cement bonds while redirecting the pipe run 90 degrees — the standard all-socket right-angle turn fitting at the dominant drip emitter lateral, micro-irrigation distribution, and small-bore instrument supply diameter in residential and light commercial PVC systems. Constructed in white Schedule 40 PVC, it is the smallest confirmed full-size entry in the 406 series and the highest-pressure rated — carrying approximately 600 psi at 73°F — making it well-suited for the drip and micro-irrigation lateral routing, instrument supply line direction changes, chemical injection line turns, and compact 1/2" all-socket pipe routing applications that dominate at this standard small-bore service diameter.

Both 1/2" slip socket ends accept 1/2" PVC pipe for permanent solvent-cement bonds, redirecting the pipe run 90 degrees between the inlet and outlet socket axes while preserving the full 1/2" interior diameter through the elbow body. This full-size all-socket configuration provides a right-angle direction change entirely within cemented socket construction — the correct choice when the upstream 1/2" assembly is an all-socket pipe run and the downstream continuation must also proceed as a cemented socket pipe run at 90 degrees. It is distinct from the 407-005 (1/2" Slip x FPT 90 Degree Elbow, confirmed in this catalog session), which provides the same 90-degree direction change but with a female-threaded outlet for a male-threaded downstream component rather than a socket outlet for a continuing cemented pipe run — the correct choice between 406-005 and 407-005 is determined entirely by whether the downstream connection continues as a socket pipe run (406-005) or terminates at a male-threaded component (407-005). It is also distinct from the two confirmed 406 series reducing entries sharing a 1/2" slip outlet — 406-101 (3/4" x 1/2" reducing, confirmed in this session) and 406-130 (1" x 1/2" reducing, confirmed in this session) — both of which simultaneously reduce the pipe diameter while changing direction; 406-005 maintains the same 1/2" diameter on both ends without size reduction. At 1/2", the all-socket 90-degree elbow most commonly appears in drip and micro-irrigation lateral routing assemblies where the 1/2" socket supply run must navigate around planting features, hardscape boundaries, and grade transitions at a full right angle; in instrument supply line assemblies where a 1/2" socket distribution run must change direction at pipe routing corners throughout the distribution layout; in chemical injection line assemblies where a 1/2" socket feed line must make right-angle turns at compact enclosure walls and routing constraints; and in fire suppression grid branch line assemblies where 1/2" socket sprinkler supply runs must turn 90 degrees at structural boundaries and grid corner points.

Rated to approximately 600 psi at 73°F — the highest confirmed pressure rating in the 406 series — this elbow is suited for standard commercial and light industrial pressure service. 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 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, and derate pressure ratings for elevated temperatures per published derating curves.

Industries & Applications:

• Drip & Micro-Irrigation Systems — Redirects 1/2" socket drip emitter supply laterals, micro-irrigation sub-headers, and zone distribution runs at 90-degree routing corners around planting beds, hardscape boundaries, and grade transitions in residential and light commercial drip and micro-irrigation distribution assemblies where all-socket cemented construction is maintained throughout and the pipe run must continue as a socket pipe run after the right-angle turn — the highest-demand right-angle turn application at the standard 1/2" drip lateral and micro-irrigation distribution diameter
• Irrigation & Water Distribution — Provides right-angle direction changes on 1/2" socket lateral distribution runs, zone supply headers, and small-bore service distribution assemblies in residential and light commercial irrigation systems where all-socket cemented construction is maintained throughout and the 1/2" socket pipe run must navigate 90-degree routing corners at landscape features, structural boundaries, and pipe routing constraints throughout the lateral distribution layout
• Instrument & Process Piping — Changes direction on 1/2" socket instrument supply runs, sample distribution line assemblies, and chemical feed pipe routing at 90-degree corners in manufacturing, water treatment, and laboratory facilities where all-cemented construction is maintained throughout the 1/2" socket instrument distribution manifold and the pipe run must continue as a socket run after the right-angle turn at routing constraints and equipment approach corners
• Chemical Handling — Provides right-angle direction changes at 90-degree routing corners in 1/2" socket chemical feed distribution lines, injection system supply pipe routing, and dosing manifold lateral assemblies conveying acids, caustics, fertilizer solutions, and other fluids incompatible with metal fittings where all-socket cemented construction is maintained at every direction change point throughout the distribution layout
• Fire Suppression Systems — Redirects 1/2" socket sprinkler supply drops, branch line distribution runs, and grid lateral pipe sections at 90-degree structural corners and routing constraint points in light-hazard and residential Schedule 40 PVC fire suppression assemblies where all-cemented construction is maintained at every direction change throughout the 1/2" socket grid layout
• Water Treatment & Aquaculture — Used at 90-degree routing corner points on 1/2" socket distribution runs, chemical feed lateral assemblies, and instrument supply pipe routing where NSF/ANSI 61 compliance and all-socket cemented construction are required at every direction change point throughout the small-bore distribution assembly
